    I just picked up a 17 EL 4x4. I had a great performance tow tune in my 5.4 F150 that I traded in (returned to stock tune first). What benefits will I get out of tuning the ecoboost expedition? It will be a daily driver for my wife but will also be towing my travel trailer now that the truck is gone. I don't want harsh shifts or to mess with my powertrain warranty but the electronic throttle improvements would be nice.

    I just got tunes for my 17 Expedition. We took a 350 mile trip to south Florida last week. The trip down I was burning 87 octane with the stock tune, cruise control was set 0n 82 mph. Got 16.5 MPG.

    I loaded the 89 Eco tune and filled up with 89 octane for the trip home. Set the cruise control on 82 again. I got 19.9 mpg. Pretty impressive.
    With a stock tune I normally get 17.5 mpg on 89 octane gas on the interstate.

    Which performance tow tune for the 5.4 did you have? Did you have to run higher than 87? I kind of like 89 towing anyway. Wouldn't mind a little finer tuning for our long tows

    Thanks, Matt

    What does the owner's manual call for? On my other Ford it says to use "91" as a "suggested" fuel. And if you use anything other than the "suggested" and have any issues with engine, they are not covered under warranty. I hate paying for premium on such a large vehicle. I've been using 91 octane. I have been contemplating E85.

    Did you ever do that E85 thing? I figure that since a couple of months have passed, if you did, we could all hear how that worked out for you.....???

    I ran the five star 87 octane performance tow tune with ODLK (locked out 6rh gear when tow haul mode was turned on), and it was a great tune. I'd still run 89 octane when it was hot and I was towing. On the 17 expy, I'm running the 5 star 87 octane performance tow tune as well, and I run 91 octane when towing. The ecoboost likes higher octane fuel in demanding situations like towing and when it's hot. I haven't really noticed a mpg difference between 87 and 91 octane though ymmv

    Are they all e85 compatible or do they have to be marked? I haven't seen anything on my that leads me to believe it is e85.

    Our Expy's are not E85 compatible. Only the 5.4 Expy's that were marked were OK.
