Oil dilution with Avgas is considered by almost everyone that flies in cold country to be an emergency
IE, if I could not get my camp stove to light, and or my generator
was kaput so I couldn't pre-heat, and a winter storm was coming, then I'd oil dilute, but only if I couldn't drain the oil and heat it over an open camp fire.
You just can't go wrong with the idea of the only thing to add to oil, is more oil, although I'll admit to "flushing" the oil sumps on engines I've gotten from others that I suspected had sludge build up.
