E85 gas mileage?

[HISSMAN]

I ran 93 in mine all winter. I just filled up with FF for the first time since early November, and wow! I forgot how much snappier it is with corn in the tank.

Just to confirm: I can run straight E85 with stock injectors and not worry about fuel starvation? If I run a mix of 93 and E85 or even straight 93, the ECU will make the appropriate timing and A/F ratio adjustments?

If you run a Lund FF tune yes you can. I mix mine all the time. Stock injectors, JLT Cold Air.

If you have a flex tune, let it learn correctly and are on a stock IM then yes.

Yeah, I have Livernois flex fuel tune. I just haven't loaded it yet since E85 is only around 50% E in the winter where I live. I have been running their 93 tune. It sounds like I can go ahead and load the flex fuel tune and let the ECU manage it.

ive sent data logs and they say it's fine so I just don't run e85

first tank was back towards end of last year. second tank was a few weeks back. might try a 3rd to try to get video of issues but I swear every time I break out phone to record, it acts fine! haha

Well if you ever decide to give us a try let me know, we have an awesome tune thats easy to use and understand and my buddy even has our E85 flex tune for his 17 gt mustang and loves the car! :cheers:

Yes sir our tune will automatically adjust all of the combinations of fuel without you seeing fuel starvation, you only need injectors once you start going further with the build such as a blower

Wow $5 a gallon? Thats insanely high! Too bad there isnt some e85 around to enjoy that tune on your vehicle!

I can get e85.. $700 for a 55 gallon drum which is what? $12.71/gal

They have a few fees to get that drum and deliver it thats why its alot more than what you would pay at a pump

55 gallons would last about 2 weeks in a daily...

Yep. Plus your guaranteed pure e85, as opposed to what you get at the pumps.. could be as low as e30 with a lot of water.

Not sure if thats really worth the extra almost $11 per gallon in all honesty, just gotta find the right station to get from and itll be pretty good

Okay what am I missing here? how can "e85 be better all around V.S. a 93 tune." when the GPM is in the toilet? Depending on the price difference (location), you may end up paying more for E85, no?

 

[HISSMAN]

Octane and depending on the price difference, it can be cheaper per mile.

I fill up e85 at 1.70-1.90 a gallon. 93 octane is about a dollar more per gallon in my area.

The annoying thing is the limited availability of e85, and it's not uncommon for the e85 pumps to be out of service at one station.

Also stations usually only have one or two e85 pumps.l, and in my experience, people love to park at these pumps to go inside the gas station.

My first partial tank of flex fuel, which is at E43, I'm at 11.7 MPG. Normally at around 13.5-14 for 93 and the same driving.
