[QUOTE="stylin99, post: 10240504, member: 723"] Hello guys. This is a great topic. One that I'm intimately familiar with as I'm the yellow '99 GT that converted last august to E85 fuel. There is a great deal of misinformation posted in internet forums, not excluding this one regarding the details of this fuel. MythBuster correction#1: CORROSION Post-1988 cars have materials designed to withstand the 10-20% ethanol content that the gov't expected would occur. Gov't mandates required vehicles to be compatible with E10. Although not officially designed for E85, any components not found compatible with ethanol, were likely removed entirely (rubber, bare aluminum, etc) Mythbuster correction#2: HEAT The relationship to Indy cars mentioned above is misleading. Note the Indy guys say Ethanol burns hotter than METHANOL. Key word there is hotter than methanol not hotter than gasoline. Due to the extra volume of fuel in the cylinder, and the characteristics of E85, it actually burns COOLER than GASOLINE (remember they burn E100 not E85). It's all in what you're comparing it to. Overall, so far, I have no complaints of vehicles converted to E85 that have experienced corrosion of fuel components. One of the other risks with the engine internals, is only under the presence of water, and only during cold start ups. If water is present during a cold startup, Formic Acid can form, which can deteriorate the piston. For this, OEM coats the piston tops on FFVs with a special coating. It's rare, but is supposedly possible if you get a bad batch of fuel. [/QUOTE]
