gas millage
Hi I have a 2006 G35 COupe 6MT With Navi:
I am getting about 17 miles per gallon. and I drive about half high way /half road. I wanted to know if this was low or not? I bought the car used about 2 months ago. Is there something that could be old and needs changing that would improve this number? (fuel something....)
Thanks,
Kaveh.

How many miles? You could check and see if it ever had it's last big service (30k, 60k, etc.) Seems about on par, maybe 1 - 3 low... but everyone drives different.
The auto is a little different just because it shifts as quick as it can to get you into that high gear for mileage.
What you could try (works in my 5 spd MR2)
Don't bog at all. Try to get each 1st gear start spotless from over-revving, and mainly bogging.
Try to stay easy on the gas in the lower RPMs, like right after you shift.
Keep the car in a lower gear for hills. That way it has more power, with less pedal effort... as opposed to a higher gear and feeling yourself give it more gas as you near the top.
I've just found in the MR2 that keeping the revs low hurts more than helps. There is nothing wrong with being at 3 or 3.5K if the pedal effort is less and you aren't driving it hard. I get better mileage shifting higher than lower.

City I get 15-17 (although on my latest tank I filled up on the slow setting - supposedly reducing air that gets pumped in on the high setting, which means the gallon reading on the pump is off if you fill up on the fast setting - and it appears I will definitely be topping 17 on this tank with no highway miles at all).
Strictly highway I get over 24mpg

For about 50 years gasoline consumption in pounds per HP created has been relatively constant..............engines at best consume 0.45 pounds per HP hour. Super/turbo run richer and consume more at 0.55 pounds per HP hour.
We [engineers] just average it out to 0.50 pounds. How many HP does a car need to cruise for an hour at constant 55 mph speed say 25-30 or 12.5-15 pounds or 2 -2.5 gallons [22-27 mpg].
Reducing the HP created will immediately improve mpg.

It also depends on the gas station you go to. I have a Chevron next to my house and i ALWAYS fill up there. I always reset my trip counter on tank fills to see how i am doing in MPG. I average anywhere from 19-22 MPG on Chevron gas. I have filled up at Hess which was sort of an emergency and the results were just bad! My fills usually go at about 300-320 miles per fill. On hess gas i went 215 miles ! WTF. I didnt drive the car any different than i would of on a Chevron fill. Also, at that same Chevron i fill up at there are 2 pumps where i can get 300+ miles per fill constantly and the rest i could never get past 290 miles per fill. Again, this is confirmed and tested for the past year and a half! So far.....
Miles per fill:
Hess - 215-220 per fill
Amoco - 240-260 per fill
Shell - 225-240 per fill
Ugas - 270-280 per fill
I fill up everytime at about 16 gallons or so, which means that these averages were taken to a 16 gallon average fill and always on 93 octane.
Hope this helps out somehow. I would say to try out different gas stations and see what results your are getting. It took me a while to realize this and then when i started testing it i confirmed it. Just my .02 ^_^
