If your fuel mixture is too rich, the burning chamber will not ignite all of the fuel, and this will make the fuel run through the piston rings down into the oil pan.
● You drive for short distances
Gas is always running down into your oil pan on most motors. When your oil temperature gets high, the gas will emerge as a fume from the engine oil.
If you drive for short distances, the engine oil won’t reach a sufficiently high temperature to vaporize the gas, and you will fill up your oil pan with gas for some time. If this occurs then replace your engine oil and filter.
A Misfire happens when the air-fuel mixture is not getting ignited. Since the air-fuel mixture isn’t getting ignited, the gas can wash your cylinder dividers, which will make the compression to be lowered. This causes a pour down and fills your oil pan with fuel.
● A faulty fuel injector
Fuel-injected vehicles have little injection devices that give the engine the fuel it needs. These injectors are worked by a solenoid, further controlled by a computer that lets a perfectly measured proportion of fuel inside the cylinders.
If the solenoid gets stuck in the open position, fuel will track down its way inside because the substance blends in with the oil.
