Has anyone encountered any long term effects of E-85? The new "Flex Fuel" cars mention more maintenance and degrade of the fuel system with the use of E-85 in their owners manuals.



I don't have any experience using any alcohol/ethanol in a race engine. But I have seen several fast alcohol bracket cars, and they run cooler. They also require a much richer air/fuel ratio. I have not heard of anything good from its use in street vehicles and this site backs up some of what I already knew, and offers some more information.

Negative ethanol info.

(Don't mean to turn this into a political thread, just adding to the info pool and people can make their own determinations.)
