    Anyone run E-85 in their non flex fuel trucks? I thought about trying a 50% mix of E-85 and regular in my 2500hd but just curious if anyone else is doing this. I know the differences between a flex fuel vehicle and non flex vehicle so no need to go there. But these days E-85 is about 1.25 cheaper than regular.

    I haven't tried it, but I've heard that the gas mileage with E85 is so much lower that in the end the price comes out about the same.

    BTW, How are you planning on keeping the engine from self-destructing?

    The alcohol in the E-85 eats the rubber parts of your fuel system.
    If you mix E85 & gasoline, it will still eat at the rubber parts, just a little slower.

    If you continue on this course, have fun REPLACING your fuel system.

    You forgot the part about fule washdown on the cylinder walls. E85 will shorten the oil drain interval by 50%. It will also cause some pretty nasty wear on your cylinder walls.

    There are some stations around here that sell up to E-20 and claim that there are no issues with doing that.
