What I do observe is the residue in my carbureted engines float bowls and carb body passages when corn gas is used. I do not have this residue when using non-ethanol gas. Same fuel tanks, hoses, and so forth. Given these engines are all older (before the ethanol fuels were mandated to create a new tax generating commodity market) I'll continue to use ethanol free fuel.
I do experience improved mileage and throttle response from real gas too.
Obviously, engines built before ethanol are not designed to use e10 and that was stated above. The residue you see is probably gunk the ethanol is cleaning out. There's no appreciable difference in today's fuels in fuel line deterioration between e10 and non enriched fuels. (Oklahoma State study et al)
Line soaked in both fuels behaved the same.
'Real gas' as we had it when your engine was built is no longer available, not even close. |
