Third, using motorcycle oil in a car will reduce the transmission performance of the engine. Due to such high friction levels in motorcycle oils, the car might face transmission lockup during its running.
This will seriously hamper the car performance and can cause damage to the transmission as well. For a more detailed post on why motorcycle should not be used in a car, check out our post here.
As a motorcycle oil cannot be used in a car, conversely, a car oil cannot be used in a motorcycle as well. This is because, car oils have lower viscosity and therefore, low friction characteristics. This low friction will not help in lubricating the wet clutch properly as it will be too slippery for the clutch.
As a result, clutch will not function as required if car oils are used in a motorcycle. Another reason why you should not use car oil in your motorcycle is because car oils contain detergent additives which has high ash content in them. When used in a motorcycle, these additives can form deposits in the piston crown and valve train, which could again damage your motorcycle performance.
Is motorcycle brake fluid different from car? There is no difference in the motorcycle brake fluid and the car brake fluid. The motorcycle and the automotive fluid are one and the same. If both the car and the motorcycle have the same DOT ratings, then they essentially use the same brake fluid in them. When to change the oil in a motorcycle?
The frequency of oil change depends on the type of oil used in the motorcycle. Mineral oil should be changed every miles. For semi-synthetic oil, the frequency of oil change is every miles. And synthetic oil should be changed every miles. Skip to content. But after some research, I quickly realized what a blunder it would have been. Motorcycle Oil Motorcycles use the same oil for engine lubrication and gearbox lubrication.
The motorcycle oil is used to lubricate as well as cool the engine and transmission components. Car Oil A car oil is used as a lubricant only for the engine parts. Lubrication This is one parameter where both the motorcycle oil and the car oil are same.
Cooling A motorcycle oil is expected to cool down the engine components along with lubrication. Viscosity This is an extremely important aspect to look for when using the engine oil in your vehicle. Typically, motorcycle oils have greater viscosity than the car oils. Compared to car engines, a motorcycle engine oil requires balanced friction characteristics as it needs to lubricate the wet clutch, which in turn transfers engine power to the drivetrain. If the friction level is too low, the clutch will not be able to engage and will cause slippage.
So what does this all mean? Motorcycle oils are formulated to handle the transmission, more specifically, the wet clutches found in most bikes. The oil needs to be slippery enough to protect the engine, but not too slippery. This means that they strike a good balance between clutch performance, engine, and transmission protection.
This is something that is not considered in the manufacturing of car oils. Well, there you have it. Not all oils are created equal.
