Any of you guys with the 6.2 try E-85? If so, how much did your MPG suffer and was there any noticable change in performance?

 

I have not heard any reports on a SuperDuty, but the Raptors are not rated to run E85.

 

Mine has the "FlexFuel" logo on the back of the truck and the owners guide says that E-85 is one of the recommended fuels (pg 381). I thought all the 6.2 engines were FlexFuel. I guess not.

 

It does support E-85. There hasn't been many mileage reports that I've found with E-85 but here's a link to a post where someone mentioned a drop:

Searching for E85 in this forum turned up few results.

 

I have been wanting to try it, but I haven't been able to find any between NE North Carolina, and Central PA. I would image between the slightly lower price and the slightly reduced milage it would be a wash in the end. I guess you could get a warm and fuzzy knowing you aren't putting out as much emissions.

 

Wouldn't put that crap in my new truck if you paid me. The loss of gas mileage more than offsets the slightly lower fuel costs. Using ethanol in gas is the most moronic thing we have ever come up with. As far as emissions go, it's just as dirty just a different type of pollution than gas produces.

 

Its not really about emmissions, its about $$$$$$ for agricorp. Its all B.S.

FYI^^
I'm not trying to start an argument thread, I just know very little about E85 and this article is very educational for those interested.

 

Let's not get into politics, or any other issues with Ethanol. The original poster wanted to know about MPG with E85. Let's keep it that way

 

PJ0B2 I have been running E85 in my truck from the day it was new last June I have 7800 miles on it now.
I really like the way it runs it feels like it has alot more torque than it has on reg gas.

I get around 9 to 10 mph with it short trips and around town. I get around 11 to 12 when I use reg gas in it.
I would not run anything but E85 in my truck.

I did get a tuner from Mike at 5 star and it did really bring the truck to life.
I have allways had Diesels before this I have had 7.3, 6.0, 6.4 and dodge cummins 5.9 and 6.7 I will not go back to a diesel after having this 6.2 gas.

I have a F250 CC 4X4 with 3.73 gears I also tow a 34' 11000# travel trailer

 

1960, how does it tow that trailer? Toy hauler by chance?

I live here in iowa so I don't get into the montains But for the hills around here and the flats it pulls as well as my Diesels did. I will run higher RPMs and will pull in 5th gear 50% of the time. But I will not go back to a Diesel After running this truck
If I went any larger with my camper I would go with the 4.30 gear.

Thanks for all the input. It sounds like performance doesn't suffer but mpgs do. Where i'm located, E-85 is only .20 less than 87 octane so from an economical standpoint, its probably a wash at best. I friend from Mn. said up there its .50 - .60 less than gas which would make it more tempting.

 

If I remember correctly, the 6.2 running on E85 in the F150 puts out higher HP/torque numbers than plain gas. Why, I dunno, probably because they can play around with the spark timing and put more fuel in moreso than with gas, and still get good enough emissions numbers for the EPA.
