I am pleased with my 6.0 2500 HD pickup. it does all that I need done. And being flex fuel is a distinct plus. Curren price today for E85 in my area is $1.27. Regular is $2.07. My 2500 averages about 10 mpg on the stuff, so at the current price that is about 12 cents a mile. For a diesel 2500 to match that 12 cents a mile, it would have to average (all miles, 25 mpg. Not likely. On road trips (empty) on E85, my 2500 has averaged about 13.8 mpg. A diesel 2500 would have to average 30+ mpg just to break even on the per mile fuel cost. Again, not likely.
If the 6.6 isn't flex fuel also, then I will not be interested. Keeping my 6.0 2500 for a long, long time is not a bad thing for me. No need to buy the latest stuff just for the ooh aah factor.
How does yours compare on E85 vs regular? Is it worth while to run it?
