Mine right now said 21 and 28, it was 21 and 29 a few days ago but I don't even think it's realistic to get that much from this engine even though I don't have a heavy foot n drive conservatively

 

I have a good mix of both City and Freeway miles. Had my G for half a year. I'm an easy driver, and I don't ever floor it on every other straight. 95% of the time, my RPMs don't go over 3k. In the most sensible driving, my MPG average is exactly 20.6. I've restarted the mileage computer a few times, the average always comes to 20.6.

 

Drove 489 on one tank. Surprised. All highway driving on that tank.

 

I am getting under 10 mph, mixture of city/hi. Usually full throttle when the light turns green. Also there is a stretch of road on the way home that I like to pop it up to 140 or so depending on traffic. I also love burning the tires and doing donuts. I feel like a kid again in this car. God Bless the Infiniti engineers. I just wish they put a bigger gas tank in.

 

27 mpg crusing at 55 MPH.

 

Hello, fellow coupe owners. I was wondering how do you get your cars to drive you more than 16 miles per gallon in a city. No matter how gently i step on the pedal, I still end up getting 12 to 13 mpg. Could it be the fact the the engine is settling in (i got the car brand new this past Saturday) and I should expect reduced consumption once certain mileage has been reached?

 

MY guess for your situation is that it is still setting in and still getting a good average. Mine was a weekend driver for the first year and it was stuck at 17MPG for the most part of that and then settled at 19.9MPG as it started being used on a daily. Now its around 20.~ pretty much all highway.

 

since i got my uprev tune ive been pushing it i see 19.1

 

is THAT WHAT IT SAYS ON your dash computer????i dont think so

 

Today was the best I've ever gotten driving down to visit friends in Louisiana... Some back roads and a little freeway. All with AC on, speeds vary due to speed zones but cruised at 80MPH for over 50 miles of the trip. NAV said I made 27.9MPG average but here is the math I did when I refilled after the trip.

I traveled 332 miles
Pumped 12.2 gallons to refill
27.2MPG !!!!

332 /12 = 27.21311475409836

I love my G! I run Royal Purple and the mileage is always impressive to me after reading what others are getting sine I switched to the Royal Purple! Also installed Stillen Stage 3 CAI in Jan 2011, no other mods (yet).

This G has 44, 421.1 miles on it right now and runs better as they add up. My G35 had 94K+ when Hurricane Ike took it in 2008 and it ran better than new for sure. Also had original clutch which was still pretty strong at 94K.
I think this G is just really starting to break in. Love it!

 

My trip computer is overly optimistic. It says 19-21 mpg's but in reality I'm getting 16-17. Damn this car has some lousy gas mileage!

 

I get about 25mpg on the highway and abaout 19mpg combined.

 

I sure hope mine goes up soon. 1K mile on the car and I get only 14 to 16 MPG with 90% city and 10% highway.

 

On the highway I reseted it and I got 28 mpg !!! I'm gonna post a picture I have a 2008 with 11,000 miles

 

in my daily commute to work (4 miles city, 50 miles hwy) round trip i am averaging about 26 mpg per the trip computer. on the highway i am driving anywhere from 60 - 70 mph. when i driving in the city mostly with some highway i get about 20-22 mpg.

i have an 09 g37s coupe automatic and i have about 13500 miles.
