Two things seem pretty clear to me:
1) Gasoline is less dense than motor oil
2) If left in open containers, gasoline will evaporate fairly quickly, motor oil will not
If these things are true, when fuel dilution occurs and the engine is off for a period of time, why doesn’t gasoline separate from engine oil, float to the surface of the sump and evaporate, reducing fuel dilution? Does the gasoline/oil combination result in a homogenized mixture so no separation occurs? Does the closed sump prevent gasoline vapors from escaping?
It would be nice to think that a sump full of fuel diluted engine oil would heal itself with time, but it doesn’t seem to work that way. Thoughts?
