Hello Everyone,
An update on the situation:
-Currently average 15.5 MPG in the city of Chicago, IL., some highway
-Firestone Firehawk Indy 500s around all 4 a month old
-Berks HFC
-TopSpeed Pro 1 Exhaust
-Stillen CAI
-No tune or other mods
-No codes, TPMS, or other dash lights.
-Only use Shell V-Power Gasoline
Would that be about the correct MPG that it would be at?

With a G37x Sedan (auto) in IA, similar weather, I've been getting 13.9 - 14.9 with mostly city driving (premium 91 octane). From what I've read, this is fairly common MPG.

Hello all,
I have a 2013 Convertible base with no aftermarket modifications. I am not an erratic driver and do not race my G37. The current issue is that the MPG counter show averages of lower than 10MPG. I had reset the counter but it still shows the low average. I would appreciate any advice. Thank you!

You cannot expect decent MPG on any Infiniti unless you start with a full tank, set your odometer to zero,reset the vehicle computer, drive 350-400 miles on a freeway, turnpike, etc, refill the tank and divide the gallons to fill up into the miles traveled.
The math calculation will be close to the vehicle computer MPG readout.
My recent round trip with my Q70 from NJ to Florida. Ten fill ups total. Four fill ups on the way down, two fill ups for local driving while in Florida, and four fill ups on the return to NJ
Below are the actual math calculations for the ten fill ups.
All gasoline fill ups were using regular 87 octane
24.98, 25.45, 22.88, 25.71, 17.34, 16.62, 22.95, 22.93, 20.2, 25.44
Mileage dropped on local Florida driving as well as slower driving in rain with traffic backups . The 20.2 MPG result was from driving home in a raging North Carolina Snow storm.
I'm on my third Infiniti and have received similar results on the road all using regular 87 octane. I do not use cruise control as it lowers MPG by 1-2 MPG. Tires are inflated to 35lbs when cold

The best mileage I get on my 2010 Anniversary Ed Convertible G37 is 20.2 mpg. When the accelerator pedal finds its way to the floor, I get closer to 19 mpg. If I want efficiency, I drive my Model S. If I want classic style I drive my G37.
