We have a newer 5.4 dump truck at work and empty it will barely get out of it's own way! Can't imagine it with E85 in the tank.
Do yourself a favor and get the V-10. In the end it will get the same mileage as the V-8 using the same fuel!
Not sure what the point is here. E-85 definitely reduces power. My Chevy Avalanche is proof to me. After a few tries with E-85, I went back to regular (10% ethanol because that is all that is available).
BUT, the Chevy 6.0 used in motorhomes (Express 4500 chassis) is NOT a flex fuel engine. It burns regular, not E-85. Based on many posts on this forum over the years, the Chevy gets slightly better mileage. Is it a deal maker for the Chevy? No. But neither is two more cylinders a deal maker for the Ford. Both have plusses and minuses.
