Gas Mileage
 

I have an 04 g35x, with a tank thats about 17 gallons. I generally get 260/270 miles to the tank, but today I was able to get 300. I was talking to a man who worked at Costco, and he said I should be getting at least 300 miles to a tank. I buy premium gas. How many miles are you able to put on a tank of gas?

All highway 350..
city/freeway half ^ that

But I beat on her so yea..lol 06 5at

Tank is 20 gal, not 17.
Measuring miles/tank is near-meaningless.

Fuel economy is measured in Miles per Gallon.

LOL I don't care what they put into my car anymore I'm like what gets the most MILES PER DOLLAR!?

K&N Panel + Rev-Up Box + Z-Tube + SxExCx V2 Kit = 25.9 mpg (30% c / 70% h)

with the money you invest in all that....how long till your parts pay for them selves?

how much are parts vs just putting the price you paid for the parts, in gas

Spent $225
Rev-Up Box $65
Z-Intake (Tube + Box) $40
SxExCx V2 Kit $120

Made Back $80
G-Tube + Non-Revup $60
Z-Box $20


So it only cost me $145 since I had to buy a new filter ($40) regardless of the upgrades, The V2 kit alone is $150 but Sean was doing a special on it. I got the kit to try and eliminate the lag in shifting from 2-3 in tiptronic, the additional voltage cleanup was a bonus:biggthumpup:, since it probably created a better spark:dunno:. I just bought a MD 5/16 spacer for $125.:JAMIN:

well my parts will never pay for them selves cause after having an exhaust I want to hear it all the times and it sounds best at around 5k rpms lol

OP, as of this past weekend, 25-28 highway (~500-540 per tank) in extremely hilly western PA or WV. In the flats of FL or NE, it may go up to 29-30 (~580 per tank). City=19-21 mpg.

No mods with the exception of running 235/55/17 tires.

Mine never gets better than 23-25.

I go about 400+ to every tank regularly. Been averaging 24 mpg with a 60/40 mix of hwy/city driving since I got the car a few years ago.

i get like 250 a tank but all city driving in san francisco with the hills i have, plus i dont drive like a grandma

Warmer temps and the fact that the oxygenated winter fuels are off the market is the likely reason for the 10% increase in MPG.

400-420 miles before I fill up. I always divide my miles by the amount I just pumped in and I usually go to the same gas station... usually the same pump.

But I have to ask, why are you taking advice from someone at Costco? That's like taking parental advice from someone at McDonalds.
