Why does my car oil smell like gasoline?

If it is in a small amount, then the mixture of gasoline and oil is not a problem. However, it is important to find out how this happens and try to troubleshoot to prevent more serious engine failures.

Of all the fluids a car uses to function properly, gasoline and lubricating oil are the most valuable.

In order for a car with an internal combustion engine to start, it must have gasoline in it, and for the correct operation of all the metal parts inside the engine, lubricating oil is necessary.

These two fluids never mix as their functions are completely different. However, there are situations when gas is accidentally mixed with oil or vice versa, and then you will notice that the oil smells like gas.

In addition to the fact that the oil smells like gasoline, it can cause problems with the functionality of the engine. Therefore, if you find this smell in your car's oil, you should find out the cause and make the necessary repairs.

You should be aware that there are various reasons why the oil smells like gasoline. Therefore, here we will tell you what are the main reasons why the oil smells like gasoline.

- problems with piston rings: Engine cylinder walls are supported by piston rings as seals. These seals provide a barrier between oil and gasoline. If the rings wear out or don't seal perfectly, the gasoline can mix with the oil. 

– Clogged fuel injector: nozzles should close on their own. But if your fuel injector gets stuck in the open position, it will cause fuel to leak out and mix with the engine oil. 

– Top up with petrol instead of oil: There are people who are not very versed in car maintenance, and although this is rare, it can happen that they accidentally pour gasoline and oil in the same container. In other words, if you used a canister to fill your gas tank and you use the same canister to supply oil to your engine, this could be the cause of the smell of gasoline in the oil.
