The manufacturer's service manual will tell you how often you should check your engine's oil level, what type of oil you should use and how frequently you should change it.
How to know when to change oil?
As a general rule, engine oil should be changed every 3700 miles or so, as great demands are made of it. However, depending on your driving style, you may have to change it more or less often. For example, if you make lots of short journeys, engine oil performance will deteriorate, because condensed droplets of fuel will get into it. Similarly, if you do not use your motorcycle very often, or if you use it intensively, engine oil quality may be reduced depending on the types of lubricant that you use.
How often to change synthetic oil ?
The rule of thumb is 3000 miles between changes, but with synthetic oil you can go as far as 5000 miles.
Regularly changing your car's engine oil and filter is one of the most important things you can do to keep your car running well. Over time, your oil will break down and your filter will become clogged with contaminants.
Regularly changing your car's engine oil and filter is one of the most important things you can do to keep your car running well. Over time, your oil will break down and your filter will become clogged with contaminants.
Changing your oil is both easy and inexpensive, so the sooner you change the oil in your car if it needs it, the better.Changing your oil regularly helps to extend your engine and keep your car running smoothly.
Refer to your car's service manual to find out how often its oil should be changed – the interval varies from model to model.
The oil can be replaced every 10,000 to 30,000 km, or every 12 to 24 months, depending on manufacturer's recommendations.

The oil can be replaced every 10,000 to 30,000 km, or every 12 to 24 months, depending on manufacturer's recommendations.
A number of criteria need to be taken into account when deciding how often it should be replaced:
Date first registered
Total distance driven since date first registered
Distance driven since last service
Engine type
Driving style
Some vehicle models tell you how far you can drive before you next have to change the oil via a maintenance counter on your dashboard. Because this information is calculated in real time, it will vary depending on how far you have driven.
Oil, which is fundamental for protecting your vehicle and ensuring that it enjoys a long life, is subject to particularly severe usage conditions.
It is therefore important to replace it on a regular basis so as to ensure that your vehicle is always operating optimally.
Oil changes are usually carried out by your garage mechanic when your vehicle is being serviced.
But you may also do this yourself if you think that you have the necessary tools and expertise.

The right equipment in order to do an oil change properly
Oil that is perfectly suited to your engine - of the right grade and in the right quantity. Use ELF Evolution oil to guarantee optimum performance for your engine.
Before using the product, the vehicle's service manual should be checked. Oil changes should be carried out in accordance with the manufacturer's recommendations.
An oil filter and new seal that are appropriate for your vehicle– Refer to the service manual.
Safety equipment, such as safety goggles and rubber gloves.
A socket spanner for the oil drain plug.
A spanner for the oil filter.
A container (tray) for collecting the used engine oil, together with a funnel.
Option to use a jack and jackstands.
Absorbent material (newspaper, paper towel, etc.) and cloth.
An O-ring if necessary.
Steps to follow to change engine oil
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 switch on your vehicle's engine and leave it to run for 5 to 10 minutes. Then make sure your vehicle is on a flat and horizontal surface. Turn the engine off, leave it out of gear 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 with 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 – they should be positioned in accordance with the manufacturer's recommendations in the service manual.
2. Unscrew the oil plug
Open the bonnet and unscrew the oil plug in order to allow air to enter the oil circuit. The plug can usually be identified by a special colour (yellow) or symbol.
Refer to the service manual if you are unsure which plug should be unscrewed.
Once the plug has been loosened, the oil will drain more easily when emptying it. It will also make replacing it with the new oil easier.
3. Change your engine’s oil
Once you have found the oil sump 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 the tray 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.
> Avoid touching it – it may be very hot. Make sure you do not drop the plug with your gloves. Leave the used oil to drain out for around 20 to 30 minutes.
Once the sump is empty, i.e., once the oil has stopped draining out of it, replace the drain plug correctly, remembering to replace the seal or washer.
Remove the used oil filter (refer to the section How to change oil filter in a car).
Install the new filter (refer to the section How to change oil filter in a car).
Fill your engine with new oil.
Before filling your engine with oil, refer to the service manual to find out exactly how much is required and what type of oil you should use. Use a funnel to fill the engine.
Pour the oil into the engine slowly, stopping and starting so that it has time to drain down. This will also avoid air bubbles and prevent splashes.
Pour in the volume of oil that is specified in your service manual or user book.
If no information about the volume required is available, we recommend that you pour in 4 L initially, then repeatedly check the oil level until it is between the minimum and maximum levels indicated.
Use the gauge while you are filling the engine in order to check the oil level.
Allow the engine to idle for a few minutes (the vehicle should be stationary, the handbrake on and the engine should not be in gear).
Switch off the engine, check the oil level again and then top it up if necessary.
5. Cleaning
You may have spilt a little oil onto the engine while filling it. Make sure you clean your engine with a cloth before closing the bonnet.
Also remember to clean any oil stains off the floor…
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, should be disposed of at a car service centre or recycling centre.
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.
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.
Then unscrew the oil filter using your filter spanner. Pull it out with your hands.
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.
Install the new filter
Before installing the new filter, clean the base of the filter at the point where it fits into the engine.
Position the new O-ring seal on the filter and apply a small quantity of oil onto it with your finger in order to lubricate it.
This will prevent it from being pinched or damaged when tightening it. Carefully tighten the new filter, but not too much.
Most manufacturers recommend that manual transmission fluid be changed every 30,000 to 60,000 miles.
When should I change transmission fluid under heavy-duty use? Some manufacturers suggest changing transmission fluid every 15,000 miles.

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.
Brake fluid should be replaced every 12 to 24 months, depending on the type of fluid selected – even though many professionals advise replacing it every 50,000 km. Over time, brake fluid deteriorates, resulting in reduced performance and efficiency. It should therefore be replaced by new brake fluid.

Over time, brake fluid deteriorates, resulting in reduced performance and efficiency. It should therefore be replaced by new 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.
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.
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.
The oil filter serves as a barrier to keep the impurities (metal, etc.) that end up in the engine oil as result of mechanical parts rubbing together and engine wear. It is thus needed to change oil filter regularly

Where is the oil filter?
Look for a cylinder nearby the engine. The oil filter will be inside the pan.
When to change oil filter?
As far as the oil filter is concerned, it does not need to be replaced every time the oil is changed. For standard use, it can be replaced every two oil changes. You should still, however, follow the manufacturer's recommendations.
We recommend to change it every 3000 Kms and ideally before winter

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.
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:
Unscrew the screws in order to open the brake fluid container cap (also referred to as the master cylinder reservoir)
Locate the receiver. The receiver has a drain in the high position in order to evacuate air bubbles
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
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
Use a syringe to inject a little new liquid into the reservoir.
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
Slowly release the brake and watch the fluid leave the pipe.
Then tighten the drain screw before releasing the handle.
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.
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.
If you want your car to last longer, learn how to change the anti-freeze coolant. Car owners should change their car antifreeze at least once a year. Changing antifreeze is not difficult.
How to check antifreeze?
Just check to see whether the liquid reaches the "Full" line on the side of the coolant reservoir. It's part of the coolant recovery system. If the liquid doesn't reach the "Full" line, open the bottle and add a 50/50 mix of water and coolant until it does. Some coolants are premixed, so check the bottle to see whether you need to add water or just use it as-is.
How to change antifreeze for car?
If you want your car to last longer, learn how to change the anti-freeze coolant. Car owners should change their car antifreeze at least once a year. Changing antifreeze is not difficult.
Coolant change equipment:
Service Repair Manual
2-3 Gallon Drain Pan
50-50 Antifreeze Coolant
Pliers
Step 1: Antifreeze car Safety Precautions
Make sure you follow all the necessary safety precautions to prevent an accident. Avoid spilling the coolant and keep pets and children away from the work area. Make sure the engine is not running and wait until it is cool.
Step 2: - How to drain antifreeze/ How to drain coolant
Place the drain pan under the radiator petcock drain valve. Remove the petcock drain valve by hand or use a pair of pliers. Observe the anti-freeze leaving the recovery tank and the cooling system as it enters the drain pan
Step 3: How to change engine coolant - Remove Engine Plugs
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.
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.
