I agree. I have never reset mine and it agrees with my average MPG over the life of the car as hand calculated by me.

 

2010 G37S Sedan averaging 18.6 MPG

 

2012 G37s Sedan average 20.9 mpg with 50/50 city/hwy

On a 60 mile trip having cruise control set to 75mph. I was averaging 31 mpg.

 

2009 Journey

mix I get 23mpg, best tank got 30mpg all highway on cruise control going about 73 mph.

 

i average 22-23 mpg. i drive 50 miles to work, mostly freeway but in LA so its traffic most of the time.

'12 S 6MT

 

Most of my trips to work are less than 15 miles each way of 70% city street driving. I average around 18 mpg with the upgrades in my sig.

 

i average about 25 miles per gallon mixed city highway

never get less then 23

 

I've gotten 99 MPG the highest acheivable. Of course I was going downhill on neutral for 15 miles where I had resettled it at the beginning. I could swear I had taken a pic but I for the love of prove cant fnd it.

 

^ actually the best mpg is going downhill/coasting IN GEAR. this shuts the injectors off. leaving it in neutral is just like idling so the fuel is flowing.

 

What part of LA are you at? I saw a malbec sedan around burbank the other day.

And I am stuck at 17mpg with mostly city.

 

Averaging about 27. Mostly hwy. when I follow my chick in her civic hybrid I got up to 35.5 (going 65-70 with her watching her 0-100mpg gauge thing from the foothills back to the beach) for about 4 trips.

 

2011 6MT Sedan.
Averaging about 15-18mpg. Roughly 60-70% city.
Remember taking a 300-400mile trip last year and at best I got 19-21mpg.
15k miles now...still cant get more out of the it even if i drive like a granny.
