17-18 city 22-23 highway

Nitrogen filled tires. I'm not sure if it improves gas mileage. You guys with bad gas mileage should try nitrogen if you haven't done so already.

 

You must do a lot of downhill driving. Only way I can get that kind of mileage is if someone tows me.

 

i get around 13 - 16 mpg....on long trips like 20 mpg which i think suckksss...my dad on his mustang gt gets 24-26 on long trips and thats a damn v8

 

the most i ever got was 450 from a tank, of pure highway driving. i must say i was quite nervous, but i think i could have gone another 20 or so miles but chose to fill up instead and not take the risk.

There was a thread posted by a guy who got 500 on a tank!

i'm running stock minus a K and N.

but for the most part i get ****ty gas mileage in the city ~16-18

 

My mileage log:
11/04/06, 375 Miles, 16.473 gallons, 22.764 mpg
11/15/06, 377 Miles, 16.121 gallons, 23.261 mpg, New Air Filter
11/28/06, 356 Miles, 15.167 gallons, 23.472 mpg
12/08/06, 381 Miles, 16.217 gallons, 23.493 mpg
12/20/06, 379 Miles, 16.128 gallons, 23.499 mpg
Most of my driving is betwen 38-58 mph. The highest I've ever gotten was about 26.1 mpg using stock oem 17" wheels. Currently I'm around 31K miles total and using 19" wheels. When I first got my car, I was doing around 12 to 14 mpg.

15-17 normal driving environment

 

+1 for 15-17 mpg

 

Normal driving (Mostly City, some highway) 15-20 mpg depending on how aggressive I drive.

Highest ever = 25.8 mpg all highway averaging 85mph on a 360 mile trip from LA to Sacramento.

 

since i got my hks....14mpg

before i got my hks...19-22mpg

(mpg went down cause i drive harder now just to hear the exhaust )

 

I don't know the exact miles but I made it through an entire trip from my Dad's house in Long Beach back home to Modesto on a full tank. The trip was roughly about 330 miles and i have about 80 miles left to go in the tank, when i got back home. So 410 miles for a full tank seems very decent for this car.

 

according to the average MPG feature on the navi it says i get 19.2 mpg

 

I got 20mpg on the first tank in my G Coupe. Was hoping for more but maybe I am driving it hard.

 

I got about 26.7 on my drive from the Bay Area to San Diego. There were hella cars on 5 South so I didn't drive that fast...only reason why gas mileage was so good.
