Re: Amsoil
Older engines had lots of sleeve bearings, not ball bearings. Hence they typically ran a mix of plain old 30 weight engine oil and gas. As two stroke oils and ball bearings came on the scene lubrication requirements changed. Auto engine oil was not designed to burn and hence carbon buildup and plug fouling was common. Air cooled two strokes also have different lubrication requirements than water cooled two strokes. Since your experience is with engines of 15 HP or less, I would say you are not risking anything compared to a 100 HP and up engine that is much more highly stressed. Also curious how you extend the ban on two strokes just by using Amzoil. And I though I heard them all! As for blaming AMzoil for failures, that won't happen as Ethanol is currently at the top of the "blame list".
