You guys sure went off topic in this section. I want to clear a couple things up. It says not to use E85 in this vehicle. You would not want to anyway. They should just take it off the market because it is taking away from the food market (corn) and there is plenty of fuel around anyway. The other problem is that anybody I know that has used the E85 told me it burns faster. In other words the MPG drops compared to regular fuel. I even noticed when I drove my Expedition that when using high ethanol added fuels that the mileage dropped. Don't listen to the government. There is plenty of oil out there and they keep finding more.
It doesn't burn faster (that would cause pre-ignition), it just doesn't have the same "power density" and more volume of it is required to get the mixture right.
