25.57 MPG consistently with my 400km trips every other weekend about 19.62 mpg consistently city driving with a 2010 MR.

Also I have a K&N drop-in filter.

But If I drive with "Spirit" then sometimes I can actually watch the digital fuel gauge drop haha

 

Being an idiot I put a few gallons of 87 in my car forcing me to burn off the tank without boosting. 28MPG! Lol

 

There is a jump depending on speed.

Averaging 70 on the highway I can get 26-28mpg

Averaging 80 I get 22-23.

 

Agreed, below 65mph I get 26-27. And it's like that for most cars.
I get amazing mileage on my civic until I go past ~65, then it guzzles gas.

 

2010 GSR

25-27 HWY 23-25 Street
AEM intake, boost controller @ 26 PSI, Walbro255 and a tune.

Before tuning it was 20-22 HWY 19-21 street

Last NASA event I did I was getting 13 AVG on the track hahah

 

I typically average around 18 mpg mixed driving (Cobb OTS Stage 1), however, on long highway runs if I keep it between 65-70, I have average 26+ mpg (w/ cruise control).

My DD Fiesta gets 36+ MPG no matter how much I whip on her around

 

I have a lead foot, so I'm averaging around 14MPG city, and 21MPG highway. Pretty normal I guess.

 

Im averaging about 22 MPG at 32mph but it varies. However on long highway drives i tend to get better MPG going 70+mph.

 

I get about 16-17 in the city and about 20-24 on the highway. Overall much better than my 09 STI which seemed to never go above 20.1! Will a Cobb stage 1 tune help?

 

26.4 MPG tons -o- highway and some DC traffic

 

I got about 25 today driving like a normal person. Pushing it a bit I get about 21-22. Mostly highway commute.

Pretty amazing how this car can behave like a sedate family sedan when you want it to, and then a killer attack dog the next moment

 

I get about 16-18 around town and 22-24 on the highway.

 

my stock 2008 GSR chugs gas under 70mph.. 70 mph - 83 mph = best mpg for me

16 - 18 mpg city (avg)
20 - 22 mpg highway (avg) .. I have gotten as high as 23.5 on one tank of gas once

 

Hey guys,

I have a 2008 Evo X MR

I am averaging about 10-12MPG in the city, and about 17-18 on the highway. AKA 280KM's and the fuel light is on.

I took out my full TBE, flashed back to stock, tried various Cobb Maps, with absolutely no luck.

I am not driving it hard either... Anybody have any recommendations?

Can't believe my buddies C6 is getting WAYYY better gas mileage

 

I added the TBE which definitely bmp'd power (97mph 1/4 m to 105mph) and increased mileage from 21-22 best case to 23-26 best case. Any "fun" lowers the mileage at least one or two mpg per tank per "fun".
