Gasoline in oil is a common problem that can cause a variety of issues, including engine failure. When gasoline mixes with oil, it can thin out the oil and make it less effective at lubricating the engine's moving parts. This can lead to increased friction and wear, which can eventually cause the engine to seize up and stop running.
In addition, gasoline in oil can also cause the engine to run rich, which can lead to spark plug fouling and other problems. This can make it difficult or impossible for the engine to start.
If you suspect that your engine may have gas in the oil, it is important to have it checked by a qualified mechanic as soon as possible.
