i get about 290-325 on a full tank before light comes on. My avg is 18-21mpg by manually calculating it. I got an 04 G35 Sedan with 145k

 

Reading all of the responses, the average is around 300 miles per tank. I don't feel so bad now.

 

I got 275-280 miles Before the gas light comes on.

 

I drive my 6 speed mostly in town and get 385-405 on premium gas but it has alot to do with driving like a granny lol

 

260 with bolt ons and 19" wheels

 

i usually get about 300 miles per tank..mix of freeway and city..have an auto 2003 G

 

I normally get 300 to 350 a tank....

 

230-250 miles, including 4 runs at the drag strip.

 

My 1998 Isuzu rodeo gets 300MI/tank. I would be mad, but it has a 3.2l. The G35+vortech I expected it to be worse. Gets about 300/tank with a bunch of highway driving. Smile on my face.

 

Before my plenum spacer install and test pipes, I always fill up at 300-320 and only fill 15.5-16 gallons so nearly averaged 20.5mpg

After the install I noticed now I have to fill up near 17gallons so avg about 18.5-19.5 mpg.

At any rate I drive about 80% highway. Depends on your car and how you drive.

 

When I fill up, it is always 15-16 gallons too.

 

2004 Sedan 6MT

21mpg. i drive till the light comes on.

i get just over 300 miles a tank.

 

I want to call bs on this, but it doesn't really matter I guess. I do 99% city driving and I am not the world's most aggressive driver either but I get about 230ish miles per tank. Anything is possible, and there are factory freak exceptions, but I just find that range unlikely for a non-hwy driven car.

 

I am averaging 21.6 to 22 in town i shift at 2k and most of my route is 35-40mph get to your desired speed slap it in 6 and barely touch the pedal. My car has the factory nave with the fuel economy meter and is very consistent with my calculations using miles and fuel volume.

 

Reading this thread made me jealous. I'm averaging 14.5 mpg. Think I get around 160 miles with a quarter tank left which is when I fill up. That's going off my nav calculations. I'm thinking I got better mpg out of my 95 blazer. I don't drive aggressive. But what kills me is no highway n most of my trips are 20 min or less. So does that sound right as far as mpg go or should I b checking stuff in my car? Air filter and oil were changed at the end of summer. Always fill up with shell premium.
