      Changing it more often does no harm.

      When should you change transmission fluid if you do mostly city driving with constant changes of gears?

      In such a case, we recommend to change your ATF even more often.

      You will need the right equipment in order to carry out properly a transmission fluid change:

      • Safety equipment, such as safety goggles and rubber gloves
      • A spanner for the oil drain plug
      • A container for collecting the used oil
      • A funnel and a plastic pipe
      • A jack and jackstands
      • Newspaper (or paper towel) and rags
      • An O-ring if necessary

      How to change automatic transmission fluid?

      The operation is more complicated on automatic gearboxes than on manual gearboxes.

      1. Get your vehicle ready

      To make your engine oil less viscous so that it drains out more easily when changing it, it is advisable to carry out this operation after having used your vehicle for more than 10 minutes. Make sure your vehicle is on a flat and horizontal surface. Turn the engine off and apply the handbrake. 
      There should be enough space under the car for you to be able to access the oil sump. If there isn't, you may use a jack to raise the car, and then stabilise it was jackstands. 
      Never get under the car when it is only held up by the jack – it is very unstable. The purpose of the jackstands is to reduce this instability. Refer to the manufacturer's user manual to find out where to place them.

      2. Check the filling cap

      Before you change your oil, make sure that the filling cap is not jammed and that you will be able to fill your sump once you have changed the oil. If it is jammed, you will need to contact a garage mechanic.

      3. Change the oil in the gearbox housing

      Once you have found the oil reservoir and the drain plug (consult the service manual) under your car, protect the ground's surface by spreading newspaper or paper towel on it. Position your container under the plug and make sure it is big enough to contain all of the oil that needs to be drained. Unscrew the drain plug using the socket spanner. 
      Make sure you do not drop the plug with your gloves. Allow the used oil to drain out for several minutes. You will notice that used oil from an automatic gearbox appears very clean. However, it should still be replaced.

      4. Drain the converter

      Once the reservoir is empty, you need to access the converter. Using your vehicle's service manual, locate the hatch that links the gearbox to the engine.
      If the gearbox and engine are separated by a grill, this will need to be dismantled. Then use your fingers to turn the converter until the drain plug appears.
      Once you have unscrewed it, pour the oil into the container. Use this opportunity to carefully clean the converter's and casing's plugs.
      Once the oil has been poured in, screw the plugs back in. Remember to reassemble the hatch or grill.

      5. Fill your gearbox with new oil

      Before filling your gearbox with oil, refer to the service manual to find out exactly how much is required and what type of oil you should use. Once you have selected your ELF oil, use the plastic pipe and the funnel to fill the gearbox housing, placing the funnel as high up as possible so that the oil flows through the pipe and into the housing.
      Once you have filled it to the maximum level, screw the plug back in, making sure that you have not left any components on the ground.

      6. Dispose of your used oil at an appropriate center

      How much is a transmission fluid change?
      Transmission repairs often cost thousands of dollars.
      How much transmission fluid change?
      An ATF fluid exchange (some people call it an automatic transmission flush) is tens of dollars. It's worth the investment if your fluid is old or showing signs of heat damage.

      The purpose of coolants is to control the temperatures of fluids and various engine parts in all weather conditions. What is a coolant? Coolant is a fluid. Coolant fluid is a special fluid with additives, because it needs to remain liquid at very low temperatures (below 0°C), but must not evaporate at very high-temperatures (above 100°C). Coolant for cars also needs to have anti-corrosive properties in order to protect the metallic surfaces of the engine's various parts.

      Procedure to replace brake fluid:

      You can follow the tips below to change your brake fluid:

      • Remove the old, dirty fluid from the master cylinder reservoir.
        Use a cheap turkey baster for this.
      • Use a lint-free cloth to wipe out the reservoir.
        Do this only if you can get in there.
      • For new brake fluid into the reservoir just until it reaches the “Full” line, replace the cap on the reservoir.
        As you bleed the brakes (which you can find out how to do elsewhere on this site), the new fluid pushes the old fluid out of the system.
        Continue to bleed the brakes until you see clean, clear fluid exiting the bleeder screw.

       

    • During operation, a little oil is always burned – it evaporates off hot surfaces in the combustion chamber.
      We therefore recommend that you keep an eye on your vehicle's oil level and top it up if necessary.

      Why change your oil?

      Engine oil has a tendency to lose its properties over time. It should therefore be replaced on a regular basis in order to ensure that your engine lasts as long as possible. Changing the oil is a straightforward operation that removes all the impurities from the engine.

      There is, however, a technical aspect to it – choosing the right engine oil is essential. Our ELF motorcycle engine oils prevent parts from heating up and getting worn by limiting friction, as well as cleaning the engine and protecting it against corrosion.

      Oil change equipment needed for your motorcycle engine oil change:

      • Oil that is perfectly suited to your engine - of the right grade and in the right quantity. Use ELF motorcycle motor oil to guarantee optimum performance for your engine.
      • Safety equipment, such as safety goggles and rubber gloves.
      • High-quality oil filter – refer to the service manual.
      • A socket spanner for the oil drain plug.
      • A special spanner for the oil filter.
      • A container for collecting the used engine oil, together with a funnel.
      • Newspaper (or paper towel) and rags.
      • An O-ring if necessary.

      There are many types of oil changes, we’ll go through an easy step by step procedure to follow:

      How to change the oil procedure

      1. Get your motorcycle ready:

      To make your engine oil less viscous so that it drains out more easily when changing it, it is advisable to turn on your motorcycle's engine and leave it to run for 1 to 2 minutes. Then make sure your motorcycle is on a stand and place it on a flat and horizontal surface, with the engine switched off.

      2. Motorcycle oil change:

      Once you have found the waste nut (consult the service manual), protect the ground’s surface by spreading newspaper or paper towel on it. Position the container under the nut and make sure it is big enough to contain all of the oil that needs to be drained. Unscrew the waste nut using the socket spanner. Avoid touching it – it may be very hot. 
      Make sure you do not drop the plug. Allow the used oil to drain out for several minutes. Once the reservoir is empty, carefully clean the drain plug and its seal. If the seal appears too worn, replace it with a new one, then screw the drain plug back in correctly.

      3. Remove the used oil filter:

      Refer to the manufacturer's service manual in order to locate the oil filter.
      Make sure that the new filter that you are going to install is the same model as the old one – there are several types. 
      You will therefore need to select the right tool for removing the filter, depending on what type it is. The filter is probably filled with oil – make sure that the tray is close at hand so that any remaining oil can be emptied into it. Then unscrew the oil filter using your filter spanner, taking care to remember how all of the components fit together so you can put it back together again once you have pulled it out.

      4. Install the new filter:

      Before installing the new filter, clean the base of the filter at the point where it fits into the engine. Then apply a small quantity of oil onto the new seal with your finger in order to reduce the risks of leakage. Carefully tighten the new filter, but not too much.

      5. Fill your engine with new oil:

      Before filling your motorcycle oil tank with oil, refer to the service manual to find out exactly how much is required and what type of oil you should use.
      How much oil for oil change? Look in your manual for oil capacity and use the funnel to add about half a quart under full capacity into the fill hole. Stop and check the level. Add or drain oil as necessary to be at about the bottom third between Add and Full. Don't overfill the oil! It adds undue pressure on the seals in your engine and can lessen its life. Once you have filled it, screw the plug back in, making sure that you have not left any components on the ground.

      6. Check the oil level:

      Allow the engine to idle for 5 minutes. Switch off the engine, check the oil level again and then top it up if necessary.

      7. Dispose of your used oil at an appropriate centre:

      Under no circumstances should you dispose of the used oil in your tray by pouring it down the drain or by dumping it into the environment.
      The oil, together with the used filter, may be disposed of (usually completely free of charge) at a service centre or recycling centre.

      Advantages of oil

      Before diving into the benefits of different oil categories, let’s sum-up main oil advantages:

      • Reduction of friction and wear
      • Equipment protection
      • Temperature Control
      • Life Span, efficiency and reliability of engine components

      The benefits of oil change are numerous for your vehicle: it should run more smoothly, and last for much longer.

      Synthetic oil vs regular oil : is synthetic oil better than regular oil?

      1. You’ll discover below the different types of oils:
      2. Mineral oil is most commonly called as regular oil. These oils are produced by untreated mineral refining (Group I)
      3. Semi-synthetic oils or synthetic-based oils are a blend of oils produced by untreated mineral refining (Group I) and composed of oils produced by mineral refining with chemical treatment (Group III)
      4. Using “synthetic oil” terminology can be sometimes confusing as it might concern 2 different categories.
      5. Synthetic technology oils are oils produced by mineral refining with chemical treatment (Group III)
      6. 100% synthetic oils are oils with 100% synthetic molecules (Group IV and V) without any mineral refining

      Is synthetic oil better?

      Why is synthetic oil better ? Compared to regular oil, synthetic oil has many advantages:

      • It flows easier in cold weather, therefore no loss of prime when the oil is cold. Also, it is highly resistant to viscosity breakdown (the ability of the oil to flow easily in all temps) from heat, friction, chemical contaminants.
      • How many miles on synthetic oil ? How often do you change synthetic oil? Synthetic oil change frequency is lower than regular oil change frequency. Indeed, there are longer change intervals for synthetic oils: 7,500 to 10,000 miles between oil changes (compared to 3,000 for mineral oil). How long between synthetic oil changes at most? Synthetic oil change intervals are sometimes said to be up to 25K miles between changes. However, we would not advice going that long! On the other hand, synthetic oil can have as well a few drawbacks.
      • It flows easily, therefore synthetic oil is not recommended for use on high mileage engines and in new engines during the break-in period because it is slippery and it limits the wearing of new mating parts within the engine.

      You understand probably better now why synthetic oil is better. Nevertheless, a synthetic oil change cost is twice as much as conventional oil. However it lasts longer, so the actual cost increase is closer to 50 - 60 percent. Switching to synthetic oil might be more expensive but with a higher return on investment on the long term.

      Synthetic oils benefits:

      Why use synthetic oil? Benefits of synthetic oil are numerous:

      • Better low- and high-temperature viscosity performance at service temperature extremes.
      • Better viscosity index (VI).
      • Better chemical and shear stability.
      • Decreased evaporative loss.
      • Resistance to oxidation, thermal breakdown, and oil sludge problems.
      • Possibility to extended drain intervals, with the environmental benefit of less used oil waste generated.
      • Improved fuel economy in certain engine configurations.
      • Better lubrication during extreme cold weather starts.
      • Possibly a longer engine life.
      • Superior protection against "ash" and other deposit formation in engine hot spots (in particular in turbochargers and superchargers) for less oil burnoff and reduced chances of damaging oil passageway clogging.
      • Increased horsepower and torque due to less initial drag on engine.
      • Last benefit among the advantages of synthetic oil : Improved Fuel Economy (FE).

        While the oil is draining out, loosen the filter using an appropriate spanner (oil filter spanner) and then wait until all of the oil has drained out. Then remove the filter and the seal.
        Clean and then install the new filter, ensuring that the seal is lubricated with some of the new oil. This will ensure that it is oil-tight, while at the same time preventing the seal from becoming worn and corroded.

      If you use cartridges, you only need to unscrew the cover and then pull out the filter. You should then replace the seal by a new, lubricated one and clean the case before inserting the new filter.

      Because brake fluid absorbs moisture over time, it needs to be changed in order to ensure that it retains its properties and to prevent mechanical parts from wearing out.

      Brake fluid types

      There are 3 main types of brake fluids: DOT3 and DOT4 (both absorbing water) and DOT5 (not absorbing water) Most brake fluid that comes in a new car will be rated DOT 3. A few will Use DOT 4, and very few will ever use DOT 5 which is a silicone based product.

      The manufacturer's service manual will tell you what type of brake fluid you should use and will show you where the container is located.

      When to change brake fluid?

      As a general rule, the brake fluid level should be checked every 100 km or every month or so, and it should be changed around every two years.

      How to change brake fluid on a motorcycle/scooter?

      Draining out brake fluid is a risky operation if not carried out properly – air bubbles can get into the circuit. Be careful – brake fluid is a hazardous fluid. It is therefore a good idea to protect the various components which may come into contact with it.

      Before changing brake fluid

      Make sure the engine has been switched off for 15 to 30 minutes so that the oil has returned to the bottom of the sump.
      Put your motorcycle on its stand so that it can be stood up and ensure that it is on a surface that is stable and horizontal. Tilt the handlebars so that the brake fluid container is as horizontal as possible

      Brake fluid change equipment:

      • obtain the recommended brake fluid
      • a container for the used oil
      • a standard set of tools

      Brake fluid change

      • First steps:

      1. Unscrew the screws in order to open the brake fluid container cap (also referred to as the master cylinder reservoir)
      2. Locate the receiver. The receiver has a drain in the high position in order to evacuate air bubbles
      3. Remove the drain’s cap and install a pipe on the drain's screw. Place this pipe in a container in order to retrieve the used liquid
      4. Remove some of the used braking liquid from the master cylinder's reservoir, but make sure that you leave a little so that air does not get into the circuit.

      • Add the oil

      1. Use a syringe to inject a little new liquid into the reservoir.
      2. Squeeze and then release the brake lever 3 consecutive times, then action the brake lever once again and hold it. Slightly unscrew the drain's screw.

      • How to flush brake fluid

      1. Slowly release the brake and watch the fluid leave the pipe.
      2. Then tighten the drain screw before releasing the handle.
      3. Replacing brake fluid - Repeat this action until new fluid appears in the pipe, without any air bubbles.
        Advice on How to drain brake fluid : each time you carry out the operation, remember to put new fluid into the reservoir to ensure that air does not get into it.
      4. Once the process is complete, tighten the drain screw, put new fluid into the master cylinder reservoir without exceeding the marker, then screw the lid back on.

      Remove the radiator pressure cap to allow the rest of the coolant to leave the radiator. Use a wrench to remove the engine block drain plugs. Let the anti-freeze flow from the engine block into the drain pan. Make sure all the coolant has been drained from the radiator and the coolant recovery tank.

      Step 4: How to add antifreeze to car - Refilling Cooling System

      Reinstall the engine block drain plugs and the petcock. Find out how much anti-freeze your car is supposed to have by reading the service repair manual. For example, if the manual says four quarts of anti-freeze, add two quarts of coolant and two quarts of water. Pour the 50-50 mixture of anti-freeze and water slowly into the radiator's filler neck with a funnel.

      Step 5: Changing coolant - Start the Engine

      Turn the engine on and let it idle for a few minutes. Let the engine heat up without the radiator cap on. Turn on the car's heater to the high or hot position. Look into the radiator to see if the coolant is circulating. This means that the thermostat is open. Install the radiator cap and make sure the coolant recovery tank is full. Test the protection level of the coolant and you are done.

    • Checking cars’ oil level helps prevent faults and most importantly avoids mechanical damage which may – in the short-or mid-term – prevent your vehicle from running smoothly.

      Checking cars’ oil level helps prevent faults and most importantly avoids mechanical damage which may – in the short-or mid-term – prevent your vehicle from running smoothly.

      Before you begin:

      • The manufacturer's service manual will tell you how often you should check your engine's oil level, as well as what type of oil you should use.
      • Caution! If you have to top up your engine's oil, it is very important that you use the product recommended in your user guide.
      • The vehicle's manual will show you where the oil gauge is on your engine.
      • Make sure the engine has been switched off for at least 2 minutes so that the oil is "resting" and at the bottom of the sump.
      • Check that your car is on a stable and horizontal surface in order to ensure that you get a good reading.
      • Get a cloth or a roll of paper towel.

      How to check the level:

      • Open the engine’s bonnet and locate the engine oil gauge or dipstick (this is usually a brightly-colored ring or hook).
      • Pull on this hook in order to remove the stem in its entirety. Then wipe it with the cloth and insert it back into the gauge.
      • Pull out the stem once again and look at where the mark left by the oil is. This is your engine's oil level. You should also see the two lines or marks for ensuring that oil levels are between the minimum and maximum levels.
      • Your engine's oil level should be between the "minimum" and the "maximum" lines on the gauge.

      How to put oil in your car?

      Never put more than the "maximum" quantity of oil – doing so may damage your engine and its oil-tight seal.
      Similarly, the level should never be below the "minimum" line so as to ensure optimum lubrication at all times and avoid engine wear.

      • If the level is below the "minimum" line, you must top up your oil immediately.
      • If you think that the level is too close to the "minimum" line, it is advisable (although not obligatory) to top up the oil.

      If you need to top up your oil, refer to your manufacturer's user manual or our website to find out which product is suitable for your engine.

      When to flush coolant?

      Over time, radiator coolant loses its properties. As a general rule, it should be changed every 60,000 km or every 2 to 4 years (refer to your service manual for the manufacturer's recommendations). Please note: radiator fluid is toxic.

      Useful to know before adding coolant:

      Before carrying out any operations, make sure that you have an appropriate receptacle for recycling these liquids and a pair of gloves.

      What is a coolant flush ? It consists in changing the coolant in your cooling system; it is something that you can do yourself if you have a little technical expertise in automotive mechanics. We would recommend, however, that you have this done by your garage mechanic, but if you want to do it yourself, the flushing coolant procedure is as follows:

      How to flush coolant:

      • The coolant should only be changed when the engine is cool – i.e., when it has been switched off for several hours.
      • Refer to your service manual to find out where the cooling circuit and filling cap are located. Also find out where the radiator's drainage tap is. The radiator is usually near the front of the car next to the engine. Clean the metal slats on the front and back of the radiator that allow air to move throughout with soapy water and a nylon brush (brush in the direction of the radiator fins to remove dirt and grim)
      • Open the filling cap over a container in order to optimally drain the circuit.
      • Position a receptacle under the drainage tap at the bottom of the radiator, then open the valve so that all of the oil in radiator coolant can drain out.
      • We recommend that you wait 30 minutes for the circuit to drain completely.
      • How to add coolant ? Put the radiator drain cap back on and then start to pour coolant into the cooling circuit via the filling cap. You should use 5 L of fluid or more, depending on the vehicle.
      • There will be air in the circuit, so you will need to add the coolant gradually.
      • Carry on adding coolant until the level of fluid is just between the minimum and maximum markers.
      • Start the engine, leaving the vehicle in neutral. If you wish, you can turn the heating up to its maximum setting in order to get the new fluid to circulate around the whole circuit.
      • Switch off the engine and recheck the level of fluid. Add more if necessary and then repeat the previous operation until the level has stabilized.
      • A few days after you have filled it up, check the coolant level again.

      Warning: used coolant should not be disposed of down the drain or in the wastewater system: it should be taken to an appropriate place, such as a garage or a waste collection area.

       

    • Transmission oil is a mixture of base oil and additives with very good anti-wear and anti-scoring properties and good stability to thermal oxidation. Manual transmissions use a variety of oils: regular motor oil, heavyweight hypoid gear oil or even automatic transmission fluid in some cases. Your owner's manual will tell you what your transmission calls for.

      What is manual transmission?

      Transmission oil is a mixture of base oil and additives with very good anti-wear and anti-scoring properties and good stability to thermal oxidation. Manual transmissions use a variety of oils: regular motor oil, heavyweight hypoid gear oil or even automatic transmission fluid in some cases. Your owner's manual will tell you what your transmission calls for.

      What does transmission fluid do?

      The key function of transmission oil is to lubricate hypoid gears in manual and automatic transmissions for cars and trucks.

      Did you know?

      When to check transmission fluid?

      It's important to regularly check the transmission fluid level between service intervals. Letting your car run low on transmission fluid can cause the transmission to shift improperly - or even not at all. It also can harm the internal parts of your transmission, which will not be properly lubricated. Unfortunately, you may not hear any noises or have other clues that your transmission is low on fluid, until it's too late.

      How to check the manual transmission fluid level?

      Checking transmission fluid is actually not so easy to do: indeed, the gearbox is not easily accessible without equipment and there is no straightforward system – such as an engine oil gauge – for determining oil levels.
      Checking the transmission fluid level requires working under the hood of your car with the engine running. This can be very dangerous if you aren’t careful. You should therefore contact your garage mechanic in order to have it checked. They will have equipment for checking oil levels and topping it up if necessary.
      If, however, you still wish to carry out this operation yourself, here is our advice:

      To be done before the beginning of your transmission fluid check:
      Get a cloth or a roll of paper towel.
      Refer to your service manual to find out what transmission fluid your gearbox requires and how frequently it should be changed. The manual will also tell you where the filling cap is located.

      Where is the transmission fluid dipstick?

      On some cars, it is easy to mistake the transmission dipstick for the crankcase oil dipstick, so make sure you are clear on the location of your transmission.Look towards the back of the engine, near the firewall. This is where the transmission is located on most cars with rear-wheel drive.On cars with front-wheel drive, the transmission dipstick is usually located in the front of the engine, connected to the transaxle.

       

       

      • How do you check transmission fluid – Step 1: 

        Park your car on a horizontal, stable surface. Disengage the clutch and apply the handbrake. Make sure the engine has been switched off for at least 2 minutes so that the oil is "resting" and at the bottom of the sump. If your car has been used for more than 30 minutes, allow the engine to rest for a few minutes so that the transmission fluid can cool down. This is important for your safety, as well as ensuring that the results are not biased.
         

      • How to check your transmission fluid – Step 2: 

        Refer to your service manual to in order to locate the gearbox's filling cap and find out what type of spanner you need in order to unscrew it.
         

      • How to check transmission oil – Step 3:

        Open the filling cap and check transmission fluid level: it should be just beneath the cap. Given that there is no gauge, you may use a metal stem or screwdriver in order to probe the oil level and find out how high it is in the sump.

        Note: the oil may also overflow. If this happens, then it is at the right level. Quickly replace the cap.

        You can use a syringe to take an oil sample for analysis. However, we recommend that you get a professional to carry this out. Remember to screw the filling cap back on in accordance with the instructions in the user manual.

      Manual transmission fluid top up

      In order to top up the oil, you have to locate and unscrew the filling cap.

      We recommend that you use a syringe or a special pump in order to gradually insert fresh oil into the gearbox sump.

      Keep checking the oil level as described above in order to ensure that it does not overflow.

       

    • Any waste oil storage tank, such as tanks containing heating oil, diesel and waste oil, should be routinely checked and maintained to avoid the risk of causing pollution, through leaks and spills. For larger oil storage solutions on commercial sites, the tank may also need to comply with the Oil Storage Regulations.

      Discover how we can prevent pollution from a waste oil storage tank

      Any waste oil storage tank, such as tanks containing heating oil, diesel and waste oil, should be routinely checked and maintained to avoid the risk of causing pollution, through leaks and spills. For larger oil storage solutions on commercial sites, the tank may also need to comply with the Oil Storage Regulations.

      It is always a good idea to keep your domestic heating oil tank in good condition, and ideally it should be properly bunded (contained within a sealed area or unit), so that in the event of a leak, the oil will not soak away into the ground.

      This can cause a great deal of damage to your property and the wider environment and can be very costly to clean up.

       
      As the owner you may be liable and even face prosecution if the oil pollutes groundwater or a nearby river. You may wish to check your home or business insurance policy to make sure you are covered for such incidents.

      Any vehicle owner knows that lubricants are vital to the correct operation of your engine; in particular they reduce wear. But it also has other, less well-known functions:

      • Cools hot areas of an engine and moving parts
      • Reduces friction: A lubricant helps to improve engine efficiency and helps to reduce fuel consumption
      • Protects mechanical parts against wear and corrosion: guaranteeing long life and efficiency of the engine
      • Keeps the engine clean: it helps to guarantee long engine life and helps to keep all engine parts in a good and clean condition, while evacuating any impurities to the oil filter and through oil changes

       

    • It is advisable to check the state of the brake fluid every 10,000 km. As a general rule, brake fluid should be replaced every 50,000 km (or every 2 years).

      It is advisable to check the state of the brake fluid every 10,000 km. As a general rule, brake fluid should be replaced every 50,000 km (or every 2 years).
      Your vehicle's service manual will give you more precise information about how frequently the brake fluid should be checked and changed and what type of fluid should be used.
      If you find anything out of the ordinary, contact your usual garage.

      Checking brake fluid recommendations: as brake fluid is a hazardous fluid, we recommend you to bring the used cans to a toxic waste center for disposal.

      Before you begin:

      • Refer to your service manual in order to locate the brake fluid reservoir. Its location depends on the type of car you have. The brake booster is on the driver’s side of your vehicle, usually up near the firewall. Just in front of that, sitting on and connected to the brake master cylinder, is the brake fluid reservoir, usually a plastic canister like the one shown here. Older vehicles don’t have a plastic reservoir; instead, the master cylinder is a little metal box with a lid that you must remove to check the fluid level.
      • Make sure that your car is on a stable and horizontal surface.
      • Ensure that the engine is cold – i.e., switched off – before taking a reading.

      How to check the brake fluid level:

       

       

      • The brake fluid container is made of transparent plastic so you can directly check its level by looking at it.
      • Visually check the fluid's level. It should never be below the "minimum" level. Your brake fluid should not get used up when your vehicle is in use.
      • So if the level falls, it means that there is a leak in your circuit.
      • In this case, we recommend that you go to your garage mechanic immediately so that they can find the leak.
      • This will avoid problems braking and prevent serious risks for both you and other motorists.

      Now that you've seen your brake fluid container empty, here is ELF's brake fluids for your car!

    • Used oil does not belong in storm drains, on the ground or in the trash. Used oil can contain heavy metals and other toxic substances.

      When to recycle?

      Each time you have used oil. Indeed, you are not truly done with an oil change until you have properly recycled your used motor oil and oil filter. Used oil does not belong in storm drains, on the ground or in the trash. Used oil can contain heavy metals and other toxic substances.

      How do we recycle the oil?

      The process of restoring used oil to new oil (by removing chemical impurities, heavy metals and dirt) is complex.
      We have developed in partnership with Véolia a plant called Osilub which uses cutting-edge technology to regenerate used oils (we recycle many kinds of oils: we recycle motorcycle oils, we recycle transmission fluid, we recycle as well brake fluid, …)
      We have also developed a new service for waste oil collection* in the Nordic countries (Denmark, Sweden, Norway, Finland and Iceland).
      This innovative system is designed to make recycling both an easy and profitable process for customers, as well as a marketable solution. TOTAL Nordic has recently partnered with the leading recycling company Stena Recycling. Together, the two groups have created a safe and efficient collection service for waste oil and oil filters. Through this cooperation, TOTAL customers have access to recycling services: a special service centre has been set up for them with a direct number and dedicated staff from Stena Recycling with the option to have waste oil picked up from their site.

       

    • Probably the most important property of oil lubricant is the absolute viscosity, which is a measure of the force required to move one layer of the oil film over the other.

      Probably the most important property of oil lubricant is the absolute viscosity, which is a measure of the force required to move one layer of the oil film over the other. If the viscosity is too low, a protecting oil film is not formed between the parts. With high viscosity too much power is required to shear the oil film, and the flow of oil through the engine is retarded. Viscosity tends to decrease as temperature increases. Viscosity index (VI) is a number that indicates the resistance of an oil to changes in viscosity with temperature. The smaller the change in viscosity with temperature, the higher the viscosity index of the oil.
