E85??

If it's about Power Wagons, all generations, this is where it'll go. This is the original PWR Forum Power Wagon Technical Discussion Section. And this includes everything that doesn’t fit in any one of the other categories related to the truck goes here!

E85??

Post by JFordBronco » Tue Jan 02, 2018 6:19 am

As I'm working my way north on a trip, I am seeing more and more gas stations offering e85. My owners manual says no, but geez, the price difference is nice!! Anyone ever use it?

If it is not advertised for use in our trucks, I certainly would not use it.

Also, my father-in-law once used that stuff in his gmc, and he stated the much cheaper cost of it was long outweighed by the very poor fuel economy that comes with using it.

As stated, hell no in non-flex fuel vehicles.

Less energy per gallon in E85, drops economy down to being comparable $/Mile.

Don't use it unless you have a custom ECU tune for it. With a tune. You will get more power out of E85, but at the cost of fuel mileage. The turbo, and supercharged guys use it as cheap race fuel. A twin turbo engine can easily pick up 100hp with a switch from 93 oct to E85 with a tune, bigger injectors, and fuel pump.

I had a rental car a few years ago that was flex fuel. E85 was really cheap where I was at. I gave it a shot, and you could watch the gas gauge needle drop at an alarming rate as you drove down the road.

The truck probably doesn't have the wide band fuel/air sensors and fuel map in the PCM to run 85% ethanol. So, it's probably a real bad idea.

It's also hard on the plastic and rubber components.

Ive been running E85 in the race car for years. Its wonderful. As long as you get it from a good station, it is not ill-tempered. It keeps carbon build up to vertually zero around the heads of valves, piston rings, piston tops, combustion chamber, etc.

However, our fuel systems and maps were not made for E85. E85 takes ~23% more fuel to have a stioch ratio: 8.8:1 vs 14.7:1. So yes you see a mileage drop. But you can advance the shit out of the timing and/or boost (for forced induction applications).

As far as emitions go, I fast passed mine with the race car sans cat. So not really sure who thinks its bad for the environment...
