Why am I getting diesel fuel in my oil?
The Causes of Fuel Dilution in Engine Oil This often happens in the region between the piston rings and the cylinder bore. Other factors include leaking of the fuel injectors, incomplete combustion of the fuel, low engine temperatures, long periods of idle time and frequent short-distance driving.
Why is fuel mixing with engine oil in the crankcase?
Causes. Crankcase dilution occurs when the fuel oil from the engine gets into the lube oil of the engine. This can be caused by the walls being wetted due to the fuel condensing in the cylinder. Another way that the fuel oil can end up in the crankcase is because there is too much wear on the piston compression rings.
What would cause fuel in oil?
If the fuel pressure in your car is too high, that may cause gasoline to get into the engine oil. An inoperative injector system can also cause this problem; because, if the engine is not firing appropriately; the gasoline will end up running down the walls of the cylinders.
