im in canada too and i get 14.2/100km with 1 year with the car, never reseted and ive calculated with distance/gaz i put and the computer is good, except when the engine runs a long time without the car going

 

^ OK, agreed...it's pretty easy to only achieve 14+ L/100km with a lot of hard city driving. In the OP he said he's getting 32mpg and then, in post #13, he said he's getting 14L/100km (20.2mpg). That's a large difference.
If you eliminate the jack rabbit starts then its pretty easy to go from 14+ to 12+ L/100km city.

 

Huh? you mean 32 miles per imperial gallon.

All these damn units!@# Everyone should go metric

 

Yes...I speak Canadian unless otherwise indicated, lol

 

Yea, I got the conversion mixed up. Lol

 

Understandable

 

14l/100km is not too good though. I get 11-12ish normally and I have come to realize that's as good as it will get for my 70% rural 30% city driving.

There is a button or setting that will change you from metric to gallons so you can let the computer do the calculation for you when you want to compare stats with our American owners on here.

 

the best i could do was all freeway 27.x mpg driving not over 65mph

total avg with local driving yeild about 22-23 mpg on good days. but down to19 mpg on bad ones.

i consider i got "good" mpg for a G35 ... LOL

 

[QUOTE=Wannabe6MT;6424576]Over the span of 110miles, doing 65-75mph, this is \
computer lies....the result is probably based on HIGH vacuum on light cruise...I get 27.2 on a 71 mph cruise on interstates...I probably could get a touch higher at 65 mph...and last I have heard several cases of 370Z getting 29 mpg. but you have to do the math...fill up, note mileage....drive...note mileage and CALCULATE how much fuel you used.

 

I got very close to 30mpg on the trip computer in near perfect conditions; 45-50 on two lane highways on a cool clear day. I got a surprising 27 mpg on a 1400 mile interstate trip this spring with cruise and driving between 70-80mph. Daily commute with a combination of city and highway I get about 19. This is with a 2008S (6MT).
