What happens if you overfill oil by 1 quart?
When too much oil is added, the level in the oil pan becomes too high. That allows a fast-moving lobed rod called the crankshaft to come into contact with the oil and essentially aerate it. The result is a foamy, frothy substance that cannot properly lubricate the engine.
How do you measure oil dilution?
A number of techniques exist to measure fuel dilution. Viscosity analysis is a significant screening technique that is conventionally performed for testing the used lubricants. Gas chromatography, flash point testing, and surface acoustic wave sensing are direct techniques for testing fuel dilution.

How do I know if my oil is diluted?
If your oil level is too high and you also notice a smell of petrol in the engine oil, there is a good chance that your gasoline engine has an oil dilution. Petrol settles on the cylinder walls during cold starts and is introduced into the oil via the piston ring. This results in a mixing of oil and fuel.
