If a large amount of gasoline does get into the engine oil; change the oil immediately upon fixing the problem that has allowed this to happen. This results in a significant reduction in the oil’s viscosity; which affects engine lubrication and causes scoring of the cylinder walls along with bearing failure.

What happens if diesel mixed with engine oil?

This diesel fuel in the cylinder can also seep past the piston rings into the oil crankcase, diluting the lubricating oil. This can damage all internal engine lubricated parts resulting in major engine failure from rapid wear.
