Many people use car engine oil in their motorcycles for a short time. However, it is not a good lubricant for motorbike engines because it has different properties.
Can Motorcycle Use Car Engine Oil? You should not use car engine oil on a motorcycle because it requires specific oil, while car oil has friction modifiers, provides incorrect lubrication, has different viscosity, is not compatible with the motorcycle, and comprises reduced reliability.
The lubricant of car engines does not damage the motorcycle engine. But, it has low performance, does not support these motors, and requires quick replacement.
Why you should not use car engine oil on a motorcycle?
It is not compatible with the motorcycle engine because the properties are non-identical. Furthermore, you cannot utilize it due to the following problems.
Specific oil available
Motorcycles have less complicated engines. Instead, they have specific designs and connected systems according to their manufacturing designs.
They have specific oils which provide correct lubrication and have better flow properties. Also, they are specifically made and designed for their motors.
10W-40 is a fully synthetic lubricant that provides enough lubrication to moving parts. It is specific for their high performance.
Furthermore, it offers exceptional lubrication proper, which appeals to riders. It has a particular formulation that increases its demand.
Riders prefer this specific lubricant for optimized results.
Car oil comprises friction modifiers
Car engine oil is different according to variable properties and distinct characteristics. As a result, it has a different formulation for various functions.
You cannot use it for the motorbike motor because it has friction modifiers. Also, its formulation includes detergents that are beneficial for the machinery of the vehicles.
But, friction modifiers are dangerous for their motors because they can alter the friction level. These modifiers for friction are specific for the dry clutch system, which is built-in for automobiles.
However, the motorbikes comprise the wet clutch mechanism, and you cannot use these friction modifiers containing lubricant for this system.
It reduces the clutch’s lifespan and causes its excessive slipping. These additives are anti-friction and cause a wet clutch slip.
As a result, the clutch malfunctions and requires replacement.
Incorrect lubrication
Motorcycle engines utilize oil for lubrication of the transmission and motor. They do not comprise lubricating fluids for different functions.
However, the lubricant of automobiles does not provide enough lubrication to their motors. It has insufficient flow according to its formulation.
It has limited functions and does not provide lubrication to the transmission. Their engines cannot work separately from the transmission.
Its motor malfunctions because its internal friction increases. Moreover, the lubrication level reduces in the gearbox.
You cannot shift the gears, which affects the standard speed levels. The transmission malfunctions and undergoes cracks and damages.
Also, it does not respond to horsepower, and the engine loses efficiency. These characteristics indicate that car lubricant is ineffective for its transmissions and engines.
Different viscosity level
The engine oil of the cars comprises a different viscosity level. It cannot support the motorbike engine because it lacks standard flow properties.
Moreover, it cannot flow to the clutch system. Its clutch comprises several discs which have friction.
They align in a series and work in a particular alignment. The metallic rings require enough lubrication for their performance and stability.
They dip inside the crankcase, which contains a lubricating fluid. The vehicle lubricant has the wrong level of viscosity and incorrect flow properties.
It cannot support and stabilize the clutch because it cannot reach all parts. Also, it cannot boost the disengagement and engagement of the clutch plates.
Not compatible with motorcycle engine
Motorbike engine exposes to environmental heat more than car motors because they lack covers. They are not inside the hoods, and heat can affect them.
Excessive exposure to ultraviolet rays increases their temperature during summer days. Moreover, their internal temperature rises more frequently than cars.
It happens because these motors supply power to all the electrical parts. Also, it provides support to the mechanical components of the frame.
Excessive work strain increases the temperature, and the lubricant of the vehicle engine cannot reduce the heat. Therefore, the cars have specific coolants for these procedures.
Motorbikes lack this mechanism and depend on the lubricating fluid for cooling. Insufficient cooling of the heated motors leads to breakdown, and it is not compatible with these motors.
It cannot perform the coolant effect, which reduces compatibility.
Reduced reliability
You cannot rely on the engine oil of the cars for your motorcycles and their motors. It comprises different additives according to their stock formulation.
These additional additives can break down more quickly under heat and pressure. Moreover, their breaking patterns are fast, which reduces the level of lubricating fluids in their engine.
It leads to repetitive lubricant changes, which is a costly procedure. In addition, the fast breakdown of additives reduces the lubrication effect of the fluid.
It cannot support the motor and reduces the rotational speed. As a result, it cannot produce enough horsepower to stabilize the clutch performance.
Can you temporarily use car engine oil on a motorcycle?
A few people use it temporarily in emergencies. You can use it for a short time according to the following conditions.
No available options
Sometimes, people lack specific engine oil for their motorcycles. In such circumstances, these individuals use the engine oil of their cars.
However, you can add it inside their motor. But, its removal is necessary when you find the relevant lubricating fluid.
The unavailability of specific options is an emergency. It allows riders to take these risks. However, its removal is advisable from the system within a day.
Negligence and infrequent use
A few people add it inside the motor and clutch system of their motorcycles due to negligence. This is because they cannot differentiate between both lubricants.
It is acceptable because the lubrication fluid does not cause immediate damage to the system. You can remove it after getting the proper knowledge about the fluid.
Taking expert advice is better before its addition which keeps the system stable. Sometimes, a few people use it infrequently to check compatibility.
Also, they save money by using this lubricant for both systems.
System dries without its oil
You can add the vehicle engine oil to your motorbike when it starts drying. However, a dried motor undergoes more failures and malfunctions.
The cracks become prominent, which leads to permanent damage. In addition, it leads to its replacement which affects the owner’s budget.
It is allowed to add this lubrication fluid inside the motor when it begins to dry. However, you cannot leave it without adding the lubricating fluid because it can lead to significant problems.
It is allowed for these emergencies, and you can save the system from permanent failure.
How to check the compatibility of car engine oil for your motorcycle?
Engine oil is a vital element for the stable performance of the motorcycle, its transmission, and its clutch system. In addition, the lubricating fluids determine the engine’s lifespan, efficiency, and longevity.
You can check its compatibility by reading the container. The bottles show all the elements of the formulation.
Moreover, the containers indicate the viscosity level, and the label shows compatibility characteristics. You can compare these values with the manufacturer’s manual.
Also, you can use international parameters and carry out the comparison. Expert suggestions are better for checking the compatibility of lubrication fluid for your motorbike.
