that's something I've noticed too. maybe it's an aluminum specific reaction ? whereas I can't remember a pre-ethanol gas tank rust from the inside out. of course corrosion happens by accumulated �condensate from metal going cool/cold. �carbs gummed up with old gas - oh yeah - as Scott wrote ; careless owners + rushed, lazy, incompetant mechanics/technicians = recycle/replace economy. I was using Marvel Mystery Oil for years before being introduced to StaBil. also before economists `discovered' that it's actually cheaper to operate a well maintained vehicle. � mike � � nothing newer than 88, please and thank you ...

There is a huge difference between pouring a pint of methanol into a 20
gallon tank of gas and pouring 3 gallons into a 20 gallon tank!

And for the record, old BMW motorcycles is one of my hobbies and I've seen a
white residue in the bottom of the mostly aluminum Bing carburetors that I
never saw before gas contained 10% alcohol. And if someone can convince me
that this is not the result of corrosion he'd make me a happy man!
