so everyone is getting 500-600km per tank?

 

I've had my '11 G37xS for about 6 months now and the average is at 14.1 mpg. That's still better than the 13.8 mpg I had in my '08 G37S.

 

Stone stock 2009 7AT Journey Nav and paddle shifters with 22K . From OC to Bishop via the 95 round trip 30.1 with A/C on and temps ~100. Drove at ~75-80 most of the time. Never went WOT except for a short run with an underpowered 3 series. I don't have pictures, but, I do have a witness. And you were thinking there is no advantage to being old? LMAO!
Normal average is 18-20 city ~28 highway.

 

My last trip on the highway, traveled about 1,400 miles through mountains and got 25.2 for the trip. I was really trying to get good milage.


2011 IPL with 6k now.

 

I am also getting around 15-16mpg on a new '11 G37. Mostly its city driving and a couple of times I took it to 80-85mph on the highway. Have around 875miles on it. Do you people feel any improvement in performance after 1000 miles?

 

Im at 1200 and performance seems to have declined... I suspect its the computer adjusting to various factors.. My MPG average jumped to about 20 from 15/16.

 

Ive been getting 10-11mpg during local driving on 89 octane gas. The only mod I have is KN drop ins. I got a 08 g37 5AT, is this normal?

 

12.1 mpg driving hard (City)
18ish mpg normal driving (City not reving over 3k RPM)
24 mpg ( 80mph on highway )
30.2 mpg on highway at 60mph

 

89??? I've never used anything but Premium 93 Octane, and try to add Lucas injector cleaner monthly... Avg ~ 18-25, 25 when mostly Hwy...

 

Took a trip to vegas for my birthday and i got about 460 miles on the tank. so not to bad for 330HP! averages about 23mpg og there was alot of traffic on the way back. so could have been better.

 

On my first major highway trip, the car reported 27.0 MPG 99+% Highway. Fort Worth - Houston - Fort Worth. Hand calculated was 27.65 mpg.

My average in normal town/highway driving is just under 20. I'll have to do more highway trips, so that I can keep the first digit in the 2's.

 

I get between 15-18 depends on how I drive that week. Lol

 

I have close to 15k on mine and have been getting very consistently 20-22 MPG.

I don't drive it nearly as hard as I could but have fun with it. I would say I do about exactly 50/50 City/Highway. I also never fill the tank with anything under 93. I would say that on a completely filled tank I get about 350 miles to the tank when filled to ~17.5 gallons. I'm in Orlando as well but do maintain consistent drive on tolls and highways to get around town.

 

I get about 14-15 mpg in my '11 IPL (6MT) in city driving which about what I got with my '09 37S (6MT). I drive somewhat aggressively.

I haven't taken a highway trip yet, but in my 37S I got about 26-27 mpg from FL to OH.

 

If I *really* try, I can get 30 MPG (indicated on dash) on a 75 minute drive that is 99% highway. No traffic to negotiate around, and around 70mph average.

I think the non-sport tires are good for MPG. Don't know if the dash indication is accurate.

If I drive like I would want to on that trip, it is more like 27. Very happy with the highway MPG on this car.

Local driving my normal very "spiritedly", I am in the high teens, still very respectable considering I am stomping on it a lot.
