You can smell a lot of engine oil in the car.

There are several reasons for smelling automobile oil:

1. The oil leaked from the valve cover drips on the high-temperature exhaust pipe. The air conditioner is externally circulated, so it will smell of oil.

This requires going to the local maintenance agency to check or replace parts.

The oil in the oil pan splashed on the exhaust pipe. It is recommended to stop for maintenance.

The problem of oiling the exhaust pipe is simple. If there is too much oil, it must be cleaned up in time. If there is little oil in the exhaust pipe, you should let the oil work by itself, because the exhaust pipe will generate a lot of heat after burning for a period of time, which will make the fuel on it evaporate quickly.

3. Insufficient coolant. The engine temperature is too high.

If the coolant is insufficient, it needs to be replenished. You can go to the professional maintenance department to change or replenish the coolant.

4. The car will smell of gasoline when it is cold.

This is caused by the aging of the valve oil seal. As the temperature of the valve oil seal decreases, the rubber valve oil seal becomes stiff and cannot be completely sealed. Oil leaks into the combustion chamber from the valve, and there is a pungent smell of cold start after combustion.

Engine oil, that is, engine lubricating oil, is known as the blood of automobile, which has the functions of lubrication, cleaning, cooling, sealing, reducing wear, rust prevention and corrosion prevention.

The main function of engine oil is to reduce the friction and wear of moving parts and remove the sludge and paint from the engine. It can also neutralize the acid generated by the oxidation of fuel and lubricating oil, improve the sealing performance of piston rings, and cool the engine by taking away the heat of moving parts. Engine oil, engine oil or engine lubricating oil is a kind of substance reinforced by additives in base oil, which mainly contains anti-wear additives, detergents, dispersants and multistage engine oil viscosity index improvers.
