i have a 2003 g35 coupe and wen i first got it with 19k on the engine it seemed i got 450 miles to the tank now i get about 350 to the tank same driving as before and i have 35k now

does it matter that i take it to the nissan dealer for oil change?

does doing the fuel injection maintenance help fuel economy?

whats your fuel economy?

I usually get about 22.5 to 23.7 MPG depending on how aggressive I drive it. I do mostly backroads driving.

i get 15mpg if im lucky

12-14 mpg for me

I've been in the mid 19's but I drive fairly conservatively with the occasional burst of speed. Love those short bursts........

14.3 avg mpg, but i **** on speed limits

right around 20.

just finished testing and i averaged around 17.5-19 (mostly city driving), which is good enough. As long as a full tank last me one week =)
50 dollars a week so thus 200 dollars for a month, not bad i guess lol

Ya, I average just over 500 KMs a tank (if I did my math right this is about 24 mpg).

I have a 2003.5 6MT coupe with 90,000 KMs on it. I baby the car and in an average week am mostly on back roads also.

i have 03 on 42k ..getting around 20mpg driving very kindly ...on other side i get like 13-18mpg

17-19 mostly in town driving

les just say that with G35...there IS NO economy.
I get around 17MPG, but comp. says i get 280 miles per tank (yet i only fill up 16 gal.)

I get around 21 mpg. I drive 80-90% on the highway and, because I drive at night when there's little traffic, I set my cruise control to about 70 mph every time.

The good thing is that my gas mileage has been getting better.

i can almost sqeeze out 500 from a tank on the highway. but only about 350-400 in the city.
