I would liek to try the E85 mix (less mpg, more power I heard).. but I still have half a tank left. Is it ok to mix the two together, or should I run down on the premium first? Anyone?

I don't see a problem with it. Your computer senses the fuel you have in the tank and makes the appropriate changes. I get about 15mpg highway on E85 and 17.5mph on 92 octane (E10).

17.5 is very nice. What's the secret except letting off the gas pedal?

I drive mostly highway with Cruise control on. Lol, that's my only secret.

I'm currently getting 13.4 off gas... (the dealer filled it, so I don't know which grade they used)

When I bought my 2010 Premium with 7 miles on it, my first tank I got 17.8mpg. Again, I drive almost all highway and I always set cruise. On E85 with a heavy foot in the city I get 11mpg. Maybe they put that in your car.

Okay, I've got an update. I just did a trip from Central Washington State to Boise Idaho and got 17mpg (calculated) on 92 E10 octane (mostly high way, but a heavy foot whenever I got to the city). On my trip back I was running Maze, E85, and got 16mpg. I had the air conditioning set at 69 most the time on both trips and cruise set at 65mph.

Sounds like the E85 is winning cause they can usually be found for 20% less in price. My local gas station here ran special Premium 92 same price as 89 which is about $3.65. So I just filled with 92 for about $78 for about 21 gallons. My next fill will be with E85, I think one station here got it priced at $3.18. As far as what's good for the engine in the long run.... anyone has any idea which one is better?

I just drove to The Indy 500 from upstate NY and got 17.8 on 87 E10.

wow.... 87?? I don't know about using that. I'm always afraid of saving a few bucks and pay for it later in hundreds.

Yeah, H2... don't buy into another thread of 87 octane. As far as which one is better for the long run.... I don't know. E85 burns cleaner and I think will keep your engine cleaner, because there is less carbon when burned. 92 octane is just fine though. If there was a station closer to me and the price penciled out, I would run E85 all the time. Can't beat 100+ octane fuel.

Been running strictly E85 for couple months now... coming out to something like 11.8 mpg... not bad for all city driving. As of right now, it's at the dealer getting something replaced so I can even pump the gas! The gas pump clicks out every time like it was full and it takes 20 minutes to fill up 1 gallon. Glad it didn't happen when i'm on a road trip.

Please let me know what they found with your gas tank not letting the pump fill it up without shutting off-I've been fighting that problem also. Been planning to have it looked at the next time I go in.

That's too bad about your gas pump clicking. 11.8mpg on E85 is pretty good! I love burning that fuel whenever I find it. The truck just feels a little more lively.
