e85 on a stock tune
Who runs e85 on a stock tuned car? All I've got is intake, HFCs, and a catback. No tuning at all. Found a local station close by the house that has e85 for $2.59 vs. regular at $2.99 (can only imagine what premium is) and was debating trying it. What do yall think?

I think you'll be needing a new engine.
The stock fuel system won't handle E85. You'll need new injectors, probably a new fuel pump, and definitely a tune. Once it's tuned, you won't be able to run normal fuel again.
Also you get less mpg out of E85.
So, is saving a buck this minute worth the repair you'll need an hour from now?

Shell V-Power in Colorado has 10% ethanol as do all "standard" gasolines here in Colorado. This used to be only during the winter months but is now year round. While politicians will try to make you believe that it is an environmental issue, in reality, it is the result of the ethanol/corn growers lobby efforts to mandate ethanol use. The one thing it does is reduce dependance on oil/fossil fuels but there are open debates on wheter it really helps as it costs energy, provided by fossil fuels, to produce. The environmental benefits are really a trade off. Ethanol produces less of some harmful by-products and more of others.
As for running E85 (85% ethanol) in a modern automobile, it can be done without a problem as long as the automobile is tuned for E85. It may require different injectors in some applications but modern engines and fuel systems are made of materials that can handle ethanol. There was a good article I read on this that I might have found from this forum but I cant remember. If I find it then I will post a link. You can actually make good FI power with ethanol because it runs much cooler than standard gasoline and allows for higher boost levels without detonation. It is much less efficient though in terms of MPG as it takes a higher fuel to air ratio for optimal operation than standard gasoline or E10 (10% ethanol).
