hey guys.. just curious on what everyone kind of mileage everyone is getting on their coupes.. currently i am only getting 280 miles to the tank.. and i drive 120 miles per day all highway..(not stop and go...) i keep my routine oil changes and plugs changed but was thinking about a fuel filter change? idk where its located..

i understand everyone car is different so here are the specs on my ride..

04 g35 coupe.. 145k
20' rims staggered 275/30/20 rear 245/35/20 front
motor dyne spacer
fuji intake..

 

again with this thread....
There is a bunch of thread people made about how much mpg everyone gets.

simply type Miles per galon on search.

 

According to my nav unit, I get ~17.5mpg which involves 70% city, 30% highway. On a normal 120 mile highway trip, I can get near 25mpg.

 

I get 23 mpg on mine and is 60% city and 40% highway
