How do you test for fuel in oil?
Perhaps the most effective technology for fuel dilution is gas chromatography . In this test, hydrocarbons in the oil sample are separated and measured. Since fuel has significantly smaller hydrocarbons than the lubricant base oil, it can be monitored more accurately.
What is the smell of oil?
Oxidation. Oxidation has a sour or pungent odor, similar to rotten eggs . It occurs when the hydrocarbon constituents of lube oil combine chemically with oxygen. As with most chemical reactions, oil oxidation is accelerated by heat and pressure.

If it has an “off” odor—perhaps like crayons, metal , or something sour—it's past its prime. To see if olive oil is past its prime, pour some into a spoon and sniff it. Sour odors mean that it's rancid. It'll have an off smell if it's gone bad.
How does gas get into the crankcase?
Crankcase gas originates from leakages that occur between the piston rings and the cylinder walls of an engine. The gas leaks down into the crankcase, where it generates a fine mist of oil droplets from the oil used for lubricating and cooling the engine.
What happens if you put gas instead of oil?
Oil serves as a lubricant in most machinery, so by running your lawn mower with gasoline (which is much thinner and a solvent) instead of oil, it is possible that the gasoline was not allowing the engine to be properly lubricated , which could lead to extensive damage to engine parts like the crank bearings, pistons and ...

How is oil contaminated by dilution?
Fuel dilution in oil is a condition caused by excess, unburned fuel mixing with engine oil in an engine crankcase. Hydrocarbon-based fuel, usually with a lower vapor pressure than the lubricant, has a thinning effect, lowering the oil viscosity.
