i get about 260-275 miles a tank (when light comes on) of 91oct

 

im averaging 10.5 mpg on E85.. lol

 

At 24 psi with 93oct: 16 city/street 23 highway/conservative

 

I have no e85 input, but you guys either beat the hell out of your cars or all need tunes bad lol

With 93, 2150cc injectors and quick dialing in I got 26.9mpg all highway driving to Ohio for the shootout.

 

I get 250 miles to a tank driving insanely conservative on 93 once I got 300 miles on a tank all were highway miles and I was stranded due to my banks computers being down couldnt buy gas needless to say I was definately running on fumes that day.

Driving completely normal not flooring it or being conservative I get about 230ish

 

im guessin most of u r gettin to ur destinations pretty quick with those mpg's LOL, 250 to a tank on 93, sweet jesus lol

 

I get 250 miles to a full tank of e85. I do alot of cruising and stay out of boost most of the time. I'm a stickler for mpg. But I love E85!

 

Well what turbo are you using? That plays a big role
Btw, injector size has nothing to do with mileage.

My car rarely gets to see the highway so naturally I get crummy mileage compared to everyone that drives on the highway.

 

This year an FP Red, last year a 20g and the year before that a stock 9 turbo. I go to the shootout every year and get 25-27+mpg driving there.

Injector size doesn't directly have an affect on MPG, but my point is I'm using an extremely large injector that wasn't fully dialed in.

 

I gotcha now. Highway I get 25-26mpg all day but I live 1.5-3.5 miles from everything here in the city and it pretty much rapes my mileage.

 

On my setup I get 20mpg on 93 and 15mpg on e85. It evens out for me since e85 prices near me are about 25% less than 93.

 

That being said, on my last tank, all city, with street racing, I got 100 miles lol

 

You're gonna get about 12-14 mpg on E85 if you do occasional pulls... not sure about highway driving. It really all depends on the tune and the way you drive it.

Some get up to 20 mpg on E85 but I've never gotten more than 14

 

Thanks for the info.

 

you should also factor in that e85 is usually .50cents a gal less than 93...
