I had a loaner G35x over the weekend and it's mpg was HORRIBLE. It was averaging approximately 18mpg overall. When I was in my G37S, I was hitting 22.

No contest.

I didn't get why it had a terrible mpg, but I'm glad I got the coupe - I bet the manual is helping out. I started off with approx 16-17mpg when I first got it 2 months ago, but now I've broken the 20mpg+ mark once I figured out when to shift.

You guys with manuals notice a difference with manuals too?

 

wow 22mpg. i am at 18.1 what level of rpm to you shift?

 

lol i avg 15 with my 6mt coupe, injens, berk hfc, hks.

thats a city/hwy mix though, all hwy i break 20.

 

^+1! Even when I was driving like a grandmother and trying to break 20 with city driving, the highest I ever got was 19. On the expressway I can break 24, but I have to stay under 70mph in order to do it. What are you doing different?

 

wooaaa i get like 11.. if 80 percent highway i get like 16...17 if i drive like a grandpa

 

I have a 7AT, i average about 16. 3 months old. gas is a biatch.

 

Shift it at 2k and you'll see really good gas mileage..

 

i get about 21 hwy and 15city shifting at 2500rpm for city and 300rpm for hwy

 

Wow that is low. I just finished cruising for about 20 miles at 70mph and it got 26.8mpg. I average about 19mpg, driving "normal" LOL

 

the manual has suggested shift speeds... lol

i get like 17 city.

 

This is when I shift and I don't push the car in the city. I shift between 2-3, but I try to stay closer to 2.

 

i drive the loaner car which is g37 sedan but i think this gets better mileage than my G37S coupe i averaged 17/gallon

 

I'm driving around an 08 G35 sedan and the MPG DOES SUCK. I mean, WTF? How could the MPG be so different from my coupe? This has the VQ35 in it and I know the 37 has better MPG but it is not a small difference. I can't wait to get my coupe back. F this.

 

I get 24-26 mpg driving highway only. I get 14 mpg city. Combined I get 18-19 mpg. I have a 6mt.

 

I know! I hate the mpg on the G35 08 sedan.
