Choosing the Correct 2 & 4 Stroke Oil for Your Dirt Bike?

The secret behind the easy movement of the thousands of components that forms an internal combustion engine is the lube oil. These components are mostly metallic and rub against each other, resulting in high temperature and wear of part due to friction. The engine oil both helps to regulate the temperature and reduces friction.

There are several types of machines, and each works best with a specific type of oil. Would you like to know the best oil for servicing your 2 or 4 stroke engines and other parts of your bike? This article is for you.

Best Oil for A Two-Stroke Motocross Bike

The older type of 2 stroke engine requires two kinds of engine oil to maintain its simple mechanism. One oil type is needed for the clutch’s lubrication, bottom bearing, and transmission, while another is required for the piston’s lubrication. This oil is usually mixed with the fuel.

The viscosity of the oil needed for the clutch and transmission system should typically be around 80w—Refrain from patronizing cheap oils that were designed for servicing cars. If the viscosity of the oil is not appropriate, it may end up damaging the engine performance.

The oil for servicing the piston and rings is usually of a different viscosity than the previous one mentioned by The Dirt Bike Review. This oil must be adequately mixed with the fuel such that it will be spent at the end of combustion. The recommended fuel/oil ratio varies from 20:1 up to about 50:1, this means for a 20-liter fuel, a 1 liter of oil must be added to it.

Make sure you refer to the owner’s manual that came with the bike. There, the appropriate ratio is usually stated, and you are required to stick to it because too little or too much oil can damage your engine’s components.

Best Oil for 4 Stroke Engine

Today, almost all four strokes engines use just one type of oil to lubricate components ranging from the transmission to pistons. No wonder they are usually called “all in one.” A four-stroke engine has an oil system that forces the oil to lubricate more than twice the components present in a two-stroke engine.

The engine of a rack mike is usually designed. The motocross gets only enough oil required per time and nothing more than that; therefore, their lubrication oil is designed to generate maximum torque from a simple, lightweight engine.

Any Difference Between A Car and Motorcycle Oil?

The process for refining a special motorcycle oil is different from that of regular car oils. They are prepared five times more addictive like anti-scuff and anti-wear, to overcome pressures that an average car would never experience.

Why Are There Separate Oil Compartments in Some Bikes?

Separate oil: In some Honda engines, there is a separation of oils, and the reason for this is so that the oil doesn’t contaminate the top end with debris it could have accumulated from the clutch. Also, the oil in different compartments have different viscosities and was produced to serve other purposes.

The disadvantage of this oil separation system is that the engine will need oil changes regularly, and a little shortage could cause big catastrophes inside the machine.

Shared oil: As some engines like KX-F, RM-Z, and YZ-F, KTM, there is a shared oil throughout the system. The advantage of this type of machine is that enough oil will get to the critical components at different levels in the engine; this way, the engine’s temperature is always reduced, and the frequency of changing oil is minimized. 

How to Determine the Best Oil for Your Bike

For recommended oil that is suitable for your motorbike is stated inside the owner’s manual that came with it. All the necessary variables, such as the ideal quantity and weight, will be written in black and white. The same owner’s manual will show you where the filling and draining points are located in the engine and monitor the oil level.

You are advised to stick with whatever is recommended inside the manual; for example, if it says you should use 20w-50 oil in your four-stroke engine, then using a 10w-30 will only be asking for trouble.

The appropriate mix ratio for fuel and oil for a two-stroke engine will also be provided for your guidance inside the manual. If you meticulously follow these specifications, you won’t need to visit a mechanic often, and the overall engine will last longer.
