It is not that difficult to find the correct oil to be used in the engine of a bike to derive ultimate driving experience from it. Different engine uses different types of oils and the key is to find the right oil made for your engine type. First of all you need to figure out whether your bike is a 2-stroke or a 4-stroke one. A little difference is there between these two types. 2-stroke oils goes in the crankcase compression of 2-stroke engines whereas the other type of engine utilizes crankcase which is a closed one. Crankcase for the 2 stroke engine is used in the induction tract. Hence you mix your oil with fuel as it acts as lubrication to the engine.
Two types of 2-stroke oils can be found, one is the injector safe and the other is the pre-mix. Most of the dirt bikes fall under the pre-mix category. 4-stroke engine oil are available in a variety of classes like 10w-40, 20w50 etc. To find the right oil refer to your user manual what oil your bike manufacturer recommends for. If the manufacturer recommends a 20w-50 for your engine, then don’t buy 10w-30. 10w-40 is commonly used in bikes. Your user manual should also contain the exact proportion of oil and gas that needs to mix for optimum performance.
Always check your owner’s manual for the exact type of oil that will work best for the bike. Once you get to know the right kind of oil, we will recommend you to use only specific brands of oils. If you are having a 2-stroke, be sure to use a measuring cup for an accurate measure of oil and gas that your bike will require to run effectively without any hurdles.
The clutch uses the transmission or gear oil to make it cool and to protect vital parts from breaking down. This oil is of higher viscosity. You must look at the owner’s manual for the suggested gear oil. A small piece of advice – never use a gear oil meant for cars on your dirt bike as it will cause immediate failure to your clutch.
Air filter oil helps to protect your engine’s life by preserving the engine oil. A small coating of this oil is applied to the air filter and it return it protects the engine by trapping unwanted dirt. Typically this information cannot be found in your manual, but you might consider using this oil.
Below are some of the recommendations that will help you to know more.

How often should I change the oil?
Again the need of owner’s manual is a requirement for knowing the frequency of changing oils for the bike. Many of us thinks that you should change oil after every race or after a gap of 5 to 6 hours. But the manual has a different story. It says that you have to change the engine oil and gear oil after every six races or every 15 hours. It also says to inspect the oil after each race or every 2 to 3 hours.
Your driving habit is also responsible for an oil change. Suppose you are riding to the limit of your bike and slipping the clutch constantly, then you have to change oils as often as recommended. In case of normal riding while you never slip the clutch, you may extend the oil change for some days afterward.
Do 2 strokes have crankcase oil?
A 2-stroke engine performs input and exhaust at the same time when the piston I sat the bottom of stroke. Input charge has to be blown at a higher pressure to the cylinder in order to force out the burnt gases and that requires a compressor. Crankcase is nothing but the air compressor in an engine. If you fill the crankcase with oil, that oil will be taken to the cylinder along the intake charge. The engine will lose lubrication and soon it will cease. The one and only way is to add oil to the fuel.
Any 2-stroke engine will require oil to function and also space for lubrication. On the other hand, 4-stroke engines have a pump based lubrication system.
Understanding dirt bike engine oil
Each dirt bike requires a unique set of oil brands keeping in mind of the engine type. Understanding the right kind of oil to be used does not have to be a difficult one. Just simply think about the type of engine you are using.
For example, 2-stroke engine oil is different from a 4-stroke one because of the lack of weight indicators. Most 2-stroke bikes uses pre mixed oil combining with fuel. Both these types of oil is made to lubricate the engine so that the moving parts do not get damaged. 4-stroke engine oils are not mixed with fuel.
Each manufacturer will tell you about the right kind of oil to use in your bike and to find out yours, refer to the owner’s manual. If you can’t find the manual, a search on the web will come in handy. Do not deviate from what your manual instructs. If it says to use a 10w-30 oil, never use 20w-50. Most common oil is the 10w-40.
Measurement of engine oil and fuel is also an integral part. For 2-stroke, you will have to combine proper oil and fuel for your engine. To get the correct ratio of oil-fuel mixture, refer to the owner’s manual. Make use of measuring cup for a fine combination. Numerous oil-fuel measuring cups are available in the market.
Engine oil is crucial to the engine which needs to be checked regularly and if required, replace it to have a smooth running engine.
What is the mix for 2 stroke oil?
The mixture of fuel and oil represents the parts of engine oil and the parts of gasoline. The ratio that is required in the 2-stroke engine can be found on the owner’s manual. In absence of the manual an online search should solve the problem. However, there is another solution for it.
Know the engine’s age. Those manufactured before 2003 will require a 32:1 ratio and those made after 2002 will need a ratio of either 40:1 or 50:1.
How to create the mix:
- Pour the right amount of oil into a clean can.
- Add the correct amount of gasoline.
- Shake or stir the container so that oil and gas mixes.
- Use the mixer before 30 days or add a fuel stabilizer to increase its life.
Things to remember while mixing:
- Do not use automobile oils as they can damage your engine because they contain noncombustible additives.
- Do not use gas with more than 10% ethanol. They attracts moisture, will cause gas to break down and finally will damage the engine.
- As your engine requires a specific ratio of oil and gas mixture for a smooth performance, so never make a guess of the ratio.
- Always mix the gas and oil separately in a clean container. Do not combine them directly to your engine.
- If your bike remained idle for more than a month, check your oil to make sure it has not been degraded.
2 stroke transmission oils:
Gear oil is primarily a lubricant that is used for transmissions or transfer cases. It has a high thickness compound and will also contain some additives. A specific comportment of additives helps in withstanding the gear sliding action smoothly. The oils that comes with a higher GL rating can withstand more and more pressure. Also modern gearboxes now requires a GL-4 oil.
In most dirt bikes, the engine oil and transmission oil are the same and there is also a common combustible engine. Motorcycles specified oils have different additives and there is no need for using oils separately. Phosphorus with zinc are additives that makes the oil volatile. A separate transmission for motorcycles and scooters deserves the best oil. Right kind of lubrication is very important for the machine for high performance. It also delivers ultra-high RPM.
The American Motocross:
The American Motocross Championship is a contest of all elite group of motocross events. Their primary goal is to cater to the needs of the community of racers. There are also stakeholders that plays a major role in this industry. With their support the racing community develops the best practices for racing and at the same time maintaining the originality and preserving the rich heritage of each of these unique events.
Their mission is to assemble everybody in and raise a common interest through sharing information for developing event safety guidelines, a standard class structure, racking up procedures, providing a schedule and overall geographical balance all through the year. This group will be responsible for developing those practices, in consultation with the stakeholders and will continue support through all the race sessions year after year.
Always remember to keep the owner’s manual nearby to determine the best ways to get the maximum power output from the bike and following the above mentioned details.
