crazed black yellow slime varnish that is left over from all
the additives and ethanol.
Same test with 91 octane non-ethanol(unleaded gas) sitting
for the same 3 week test, re-stilled got him no slime
but just a tad yellow and very very faint varnish smell.

I know what I'll be putting in all my engines.
Interesting,this is why I feel addatives are a must(for me personally) if you plan on keep mowers and trucks for years with little to no sludge,varnish,valve train,and/or injector issues.

Every mechanic that I have spoken to in this area speaks of ethanol and its negative effects.Maybe other parts of the country are different,I do not know,but around here,it is not good.
