Usually less than 15. 10~15
All local driving. Highway only on weekends.

 

wow... i drive 50% highway 50% city and mine reads 24.5mpg. i have 18.5k miles.

 

70% freeway & 30 % city averaged 25mpg. Car only has about 1600miles.

 

60% highway with 30K miles and I average about 26mpg. I can get it up to 28 if I am careful and down into the teens if I drive like a bat out of hell.

 

21.8 mpg for me and that is a 50%/50% mix. Of course I am coming from a Jeep GC with the HEMI that averaged about 13 mpg. So for me this is an amazing improvement.

 

16.8 MPG. 90% city. I shift at 5k+

 

12.4 L/100km, >90% city driving. No stop&go crap though. I avg around 40km.
( this is ~19mpg @ 25mph for most of you )

 

14.8, 90% in NYC traffic

 

19.1 -- i really don't get how some of you guys get 26+ on the freeway. i have 40k on my 2010 (all original miles) and all i DO IS freeway 98% of the time. i really can't imagine my tune + 4.083 ring and pinion indent my mpg that much...

 

20.5 over the last 1500ish miles. About 80% city and I play around in it alot. Plenty of things I shouldn't be doing on public roads.

 

20.4 with 85% highway. This car sucks when it comes to gas mileage...definitely disappointed in that department.

 

Usually 21.5 Was early on the way to airport this morning and cruised at 70 read 31.0 Interesting gas mileage and repair info on truedelta.com

 

I always get 26 mpg if its 100% freeway driving, at ~70mph, with no extra weight. If I slow down to cruising at 55mph I jump to 28mpg. The only way to measure it though, is get up to cruising speed, reset the car fuel economy display. I trust what the car calculates. I compared it to my manual calcs for nearly a year when I had my X and it was always with 0.2.

 

I bought a used 2011 G37x sedan AWD just 2 days back, and the Avg Fuel Economy display says 21.9 mpg.
That number seems pretty good after going through this thread, previous owner must have been a conservative driver

I will keep posting on what mpg I am getting on my first tank of gas.

 

Exact same stats over my way.
