A similar line of reasoning would be that one cigarette won't give you lung cancer, and one big mac won't give you heart disease.f while it's true that most of the oil samples that get sent out for testing are used oil from a 4-stroke's crank case, to determine the health of the ENGINE, there is no reason you couldn't send out a sample of the oil you intend to use in your 2-stroke to test the health of the OIL.
