Mileage with E-85.

260 miles per tank Before the light comes on. Never ran mine empty, when I fill it up it reads always 13.2 gallons or lower on the pump.
Strange thing is with my tune, I get better fuel economy while staying hard on the boost. :/. So what I'm sayn is that I get Better fuel Econ if I drive my Evo hard. Different fuel brands will affect this but I put nothing less than shell 93 Oct in mine everywhere. I never use the bs fuel additives. I'll use Seafoam every 15k-20k miles. 1/2 can through the brake booster vacuum line(running) 1/2 into oil filler/head(cold) & 1/3-1/2 into the fuel tank(full fuel level and let sit for 10-15mins after adding)
Mods: Star spec 255/40r17 tires(35psi front/33psi rear) fmic, uicp, licp, intake, 255lph, 272s, Downpipe, cbe, test pipe, Evo IX Turbo @26psi tuned by Topspeed rated 350whp/358wtq
85k+ miles
I've tested this many many times because drive every weekend back and forth fom middle Georgia to ft. Bragg N. Carolina. Cruising afr=14.2+*
I can literally watch my fuel lever go higher when Im WOT. Sitting at an idle of 800-950rpm is it's worst time.
Hope this input benefits someone

I get about 16mpg with a mix of city and highway driving and occasionally getting on it. Usually about 180 miles on a full tank when the light starts to come on. Cruising AFR's are around 14.7 and WOT is tuned between 11.8 and 12.0. I could definitely benefit by increasing the timing in the cruising load cells and spending more time tuning the load cells hit when partial throttle accelerating as that's where I'm sure I'm wasting gas as well as throttle response.

^ Likewise, man. I'm not terribly concerned about the fuel mileage. The benefits more than make up for it. There are about 4 pumps available in my town, all less than 10 miles away but it would be nice to have a little more buffer zone before I have to worry about chasing a pump down to fill up.

My evo gets about 17-18 on 93. I know I drive the **** out of it but how much worse off would I be on E85. My only worry is there's no E85 by my house just by my work, about 30 mi apart.
. Im sure it will be worth it though

I only lost about 10% of my mileage switching to E85 from 91 octane. My theory is the increased timing I'm running is keeping me out of boost more in everyday use.
