[QUOTE="BigJ, post: 149596, member: 62"] Just a sec guys... I know you probably know this, but only the 5.4s are Flex Fuel. There are relatively few of us around compared to ya 6.2 fellers. You're not trying to run the stuff, right? Storage: E85 doesnt tend to separate, given that its mostly one chemical (alcohol). Its biggest concern is water. If you can keep the water out, it will last you for years. Keep the lid on tight and you should be good to go. Gasoline on the other hand is made of several chemicals that don't like each other, and so they separate. Once separated, you're not going to get them to recombine. Estimates are anywhere from 2 to 6mo if you push it, depending on how long the gas was stored after refining before you pumped it (sometimes a month or more). Performance: as pointed out earlier, if you tune for the higher octane (resistance to pre detonation, not an indication of power or potency or anything like that) you can play with the firing timing of your engine; you can basically maximize the compression of the air fuel mix before it blows up resulting in a more powerful explosion, meaning more power. But you have to tune for it. Run on your normal gas tune and you will see no improvement, and probably less performance. Government subsidies: E85 is very expensive to produce. The gov has been offsetting the cost of that production by kicking in tax dollars. When those tax dollars go away this summer, the refiners will have to pass that cost on to us. That will likely make their product cost more than the competition (gasoline). Combine that with E85 inferior MPG and its unlikely many will buy it anymore. So its not a matter of freedoms, its a matter of economics. [/QUOTE]
