Flex fuel

I have a 08 F-250 diesel and I love it. But I want to move up to a F-350. I am seeing these flex fuel motors more and more, so I am wanting to hear some feed back on this. Thanks

In my opinion, not worth it. While flex fuel may be 25% lower in cost, my experience was a 30-35% reduction in mpg.

Flex fuel makes some people feel good, but not really worth it either, I think. It's just a gas motor with different tuning and seals to handle the ethanol. Most engines can run on E15 anyway, straight out of the box.

Was of the understanding that "flex fuel" applies to the ability to use E85 in gas engines. I am not a 5-er but can't imagine the "need" to upgrade to an F350 but not go with diesel Vs gas--not sure I understand the op's question??????? Is "flex fuel" now a trend in diesels that can/built to use higher levels of bio-fuel?

think EPA and the gooberment that decided that ethanol was a good thing (you know the ones that forced MTBE on us too!)

EPA - the giver of all the pollution controls that kill many mpg's and hp's

Not worth it!

The Ford 6.7 diesel can use B20, which is 20% bio diesel. My 16 year old diesel can do that too, so no big deal there. Just advertising, and government requirements.
