Was that on the dashboard display? You were probably doing well at that moment, but the mpg on the display is usually optimistic.

Driving around Portsmouth and Chesapeake, with all their damn traffic lights, my display will often tell me I'm getting 22mpg or something. Then I look at the gallons I'm putting in the tank and the trip odometer I reset at the last fillup, and I calculate 18mpg. 20mpg is a really good day.

When I was on the highway Saturday and the display told me 27.5mpg, I was pretty skeptical until I did my own calculation:
195.8 miles / 7.045 gal = 27.79 mi/gal

...And it's a bit sad that I have a Japanese 4-cylinder and have to draft an 18-wheeler at 60mph to get that gas mileage. :-/

 

Average 20mpg on 91, 13mpg on e85 now but I get on it a little more.

 

average 20mpg City & Highway

 

Around 26-28 if I consciously cruise at 60, and roll down hills.

Like 15-16 if I drive how I normally drive...

95% highway on 93

 

I only get 18-20 mpg between city and highway driving....

 

It's legit but if you get on it... Our camry would get 40 on a all highway trip.

 

18 or so if i'm light on the throttle on e85 and about 22-24 on 93, this is for highway driving. But I'm running 1300 CC injectors with a borg warner 7670 so I feel like that's pretty good.

 

On my 91 map i get about 25 mpg highway. i have a big turbo though and doesnt spool as much

 

I dont know what i did.i get 40mpg.

 

I have full boltons and average 170-180 miles until the light cones on. I usually pump 10-11 gallons.
It comes out to 14.5-15 gallons per fun gallon!

 

Did you swap in a VW diesel engine?

 

I get about 18-20mpg/200 miles a tank, with mostly hwy driving

93 Tuned with bolt-ons

 

I knew the Evo was going to get atrocious mileage compared to my other cars, but I don't get nearly as bad as others here report.


I'm on MAP turbo-back exhaust, Grimmspeed BCS, K&N intake and Radium dual catch cans. I used the Cobb AP stage 3 ECU reflash and I drive 180 miles a day to work. 20 of those miles are city miles.


If I keep if at or below 70 I get 24-26 MPG. Anything over 70 cruising I get 22-23.


It doesn't help that our car is very heavy (3500+) and the gear ratios are not designed for it. My plan for next year is to send out my transmission to Sheptrans to get the revised 5th gear and final drive to lower the ratio to get better highway gas mileage.

 

Yeah there's a lot of factors. Roads, amount of uphill/downhill, aero on the car. (I took my APR GTC-300 off for a couple of days while I recleared the clearcoat, and for that time period I was getting about 2-3 MPG's more than usual) Thinking about getting a Doluck trunk for non-track/show days....

Also as people had mentioned the size of your turbo/tune as well. Mine spools pretty early now as well, so I'm in boost a lot more often now as well.

 

I averaged 18 on my last fill up. Mostly highway, but a lot of pulls since I just got the car.
