I average 22-23 on my '07 Sedan 6mt. 40% City, 60% Highway. I usually shift between 3500-4000rpms and when entering freeway onramps, I always gun it to 6500+ rpms.

 

21-23mpg 70%-freeway 30%-city with a bit of redline a couple times. I couldnt go without hitting redline. I tried. 340-360miles out of 16 gallons. Running on Stock 19's. Not too bad. Could be better though

 

i usually shift around 3-4k rpms, i set me rev limiter to 5k to remind me to shift if i wanna race or trying to have some fun with my G

before i install the z tube, MPG was around 16-18. (well i drive my G usually @ 85+ on freeway)

after i install the z tube, MPG is around 18-21 (again, driving @ around 85+)

the z tube is a good buy lol

 

After 3027 miles from AZ to Boston, the computer says I averaged 24.2 miles. 2003 AT sedan.

 

thanks for all the info guys!

 

I'M a happier owner of an 05'coupe 6MT.been checking my mileage religously and the best i been able to squeeze out of her was 25.8 MPG @70MPH this is w/bone stock w/M-1syn. & M-1 filter on 20"Axis. I installed my Z-Tube/drop in K&N today and took a little trip down I-10 about 90miles.stoppped and refueled and to my amazement received 30MPG!! I know,i'm not going to get to happy until i see this over time,but it did put a smile on my face and hers!!

 

stop lying!!! lol

 

If it is anything like mine, you need to subtract 1 or 2 mpg from that for the real mileage.

 

 

wow imoressive numbers some of you have , i have the 07 g 35 coupe and this thing eats gas like no tomorrow, all i do i fill it up, like 14 miles to a galon average....

 

Same here. 2007 auto.
75% city / 25% highway - 14-15mpg.

Come on, somebody beat me already... I get 9... no joke, 9 mpg !!!!

 

Wow, this thread has pretty much convinced me that an 07 g35 sedan will not be my next daily driver.

 

Anyone claiming they only get 9 MPG either isn't telling us the whole story or has serious mechanical problems. I would disregard that figure in your decision making process.

 

Or lives in a northern climate, makes 1 mile trips, and warms the car up for 15 minutes before leaving. Then drives at 80mph
