I've been getting better with my 2011.
I got it 1 month ago, started with doing 20 MPG then driving sanely I've been doing 24.6 but with mainly city (70%). I have also been keeping track on fuelly app to see how it is going and that shows that I'm doing 27.1 MPG so wondering if the G ave mpg is kinda off?

I would love to do 27+ mpg so I'll try to shoot for that. I have just installed an exhaust so right now have a heavy foot, once my thrills go away I'll be back to normal driving and see what's up.

I notice the 87 Octane, doesnt hurt the engine? No pings or anything?
I know on my Evo that's a no no but with the G i'm not really familiar how things are.

 

I've been averaging around 22 mpg is tht normal or good?

 

around 21 mpg with smart driving habits

 

about 17 for city, 22-24 highway

 

Just did a fill up driving 90% in DAa mode. i'm doing 23.6 mpg
60% granny 40%
i have a muffler delete done for mods

 

i personally average around 21.6

 

18 mpg here
was made possible by lowering two inches front and back.
sitting on -6.3 camber, rear wheels at 19x11 with some hankooks 275/35.
oh and muffler delete.

 

drove from bay area to la and got about 28.5mpg, strictly hwy. had 3 people, some luggage, and no mods. but around the city/hwy, I average about 21.5

 

Just got back from a 2300 mile trip. Averaged 27 mpg in cruise @78 mph for most of the drive. Drove through the mountains in Kentucky, W. Virginia, Maryland, Pennsylvania and New York. I love this car it doesn't deviate one bit on speed from the bottom of the mountain to the top. This is the perfect car for long trips. The car is a '08 6mt coupe, all stock. The best mileage I have gotten was last year through Western Tenn., mostly flat. I averaged 29 mpg on that trip @75 mph.

 

Rarely get better than 22 mpg even on the highway.

 

2013 Sedan, been averaging 26.8 with majority freeway

 

Was thinking about getting the R2C intake. If I drive the same way I do now, just cruising most of the time, will I get better gas mileage? Don't want it for the increased hp, just want to increase my MPGs

 

18.1 for me. But i have been driving pretty aggressive since I got the car a month ago.

 

19.2 in LA traffic. 30 miles each way to work. i don't usually drive on a clear free way.

Very aggressive. 6MT '12 Sport

 

It's going to take you 10000000 miles (or abouts) to recover the cost in any gas savings. Still, I've got a Stillen Gen 3 for sale if you want PM me (south OC).
