What is your avg mpg and about how many miles do you get per tank?

 

Its not good anywhere from 120-160 miles a tank

 

most i got was about 18 mpg highway only,
city is less than that

 

i am at 18-19mpg with 75% highway 20% streets and 5% smashing on the car.

I am running mid 15's on my cruise afr, which I am going to up to 16.5's in the up coming weeks. I am also going to lean out my idle afr which is now at 15.0. I am also going to lean out all my low boost areas, and add more timing in the low boost areas.

I think that 20-22mpg is possible with my existing driving habits.

As far as how I measure my MPG, I have 5 gallon cans at home. I will run the car to as low as it will go, and put 10gal in and repeat and then just calc my mpg from that.

My brothers STI is getting about 15mpg with 40%highway, 40% streets, 20% smashing. He just switched to E85 and is loving it. When he did his first all highway test he got about 18mpg.

 

I got 350 miles out of my last full tank of e85, and that was getting on it a bunch of times also

 

WOW, 120-350 MPH is a pretty big difference.

 

19-21 mpg , 85% hwy. /15 % local

I get about 250 + out of a tank. Most was 300 all highway.

On 93 I had 23-25 mpg

 

I get about 14.5mpg City driving.

 

WTF? 350 miles on a tank? That's 25 mpg. I'm getting 250 miles which is a little over 17 mpg.

Don't get me wrong, if you really are getting 25 mpg, please share the secret. I'd love to get about 20-22 mpg.

 

Retune In 2 weeks car was tuned in Cali it's in Texas now

 

Figure 25-30% lower fuel mileage. Its not rocket science. Its mathematical.

 

That sounds like a lot of Highway.

Also to get your MPG up, lean afr's and lots of timing. Also dont drive your car in boost.

I think that if everyone can get 20-22mpg with mixed driving E85 is a huge win.

 

i get about 280-320 all highway. speed ranging from 55-65miles per hour. oh yeah thats staying off boost!

 

I've averaged 14 mpg since July 2008 when I first converted to E85 approx 40K miles ago; this is 98% in-town driving.

 

15-16 MPG at Streets & Highway.
