I have a 08 g37 coupe and my mpg have stayed stuck at 16.2 mpg on the dash display I only drive about 4 miles to work how Can I reset the dash display ?

 

Info button, fuel history, reset fuel history. Crap...I have a nav display on a 2010...might be different. But that's how I do it

 

Press and hold the lower button on the right of the gauge cluster. If you have the owner's manual it'll have all the info you need.

 

Done thanks

 

Yea it's the same as the 08 but I meant in the dash lol got it done but thanks though

 

16mpg? Ouch ... I drive slightly aggressive and get about 19... glad you got your reset done though.

 

No problem, glad you got it done.

^^^This. I drive pretty aggressive getting on the freeway and do about 70 on the freeway and I still get about 23 mpg mixed. Ouch indeed

 

Are you guys driving an 08 or not? 08=5speed 08 and above= 7speed. I have an 08 and with some aggressive driving I'm averaging 18.3 which IMO could be better lol.

 

I don't know what I get. I know it's better then the 12 I was getting in the SRT8...

 

My drive to work is a 12 minute city drive with a good 5-6 traffic lights. At best I get 18mpg. Although our engines are awesome....godd.amn is it awfully inefficient.

 

I agree 😞

 

Good lawd that's terrible!

 

I only get poor MPG when the wife uses mine for short trips while in Florida

On the way down and on the way back I get very good MPG

some of the commutes described here directly relate to the resulting poor economy, not as much driving habits. a 4 mile urban commute? a 12 minute city commute with lights? these are very short city commutes which are the worst possible scenario for fuel economy. the engine runs "rich" for the first few minutes, and just after engine and driveline fluids warm up the car would be shut off. so not only is the stop-n-go driving inefficient, so is the operating condition.

this reminds me of a buddy who sold his mazdaspeed3 and bought a g35X (5AT) so his g/f could drive it on occasion to her work. they lived downtown and she worked downtown (don't ask me why she even needed to drive in the first place). my buddy, who is from europe where fuel economy is a big deal, complained endlessly about the mileage. being a G fan at first i defended it, but then told him that having a 3.5L engine idling in traffic is obviously going to gulp fuel more than a little 4-cyl so what does he expect? leave the car at home for short city drives if mileage was such a concern - plus, parking is a pain downtown...

anyways, for those who have no choice but to use their cars for stop-n-go urban commutes, you need to be realistic about fuel economy numbers. try ethanol-free gasoline to see if that helps. it usually extends my range by 5-10%.

my 10 mile commute is 95% "city" driving with a bunch of lights and hills. i get 11.2L/100 which is ~20mpg (US gal). have been doing so for 4+ years with little change - except a small dip in winter to account for running accessories. i can live with that mileage based on my commute and the fact that this is a heavy-ish sport sedan with 330hp.

 

Mine is a 20 mile mixed commute and I am in a 2010 6MT. 23mpg overall avg isnt too bad in my book
