Yeah, so am I doing something wrong, or how do you guys gauge it?

 

Fill it til the pump stops, drive til you want to fill up again, and then fill til the pump stops. Miles divided by gallons. Sounds like you are doing.

 

well not to get anyone mad but im doing 31 mpg at least.. as long as if i keep my foot out of its a$$ which is hard though but eh im happy.. does just as well as my mazda 3 did lol

 

i just puta cai on my car about a month ago, and my gas mileage has shot up. i was expecting a small increase, but i went from about 18 mpg around town to easily over 20. if i take it easy, i can get close to 23. that cai has probably already paid for itself lol

 

I got 25mpg last check and I have 150,000mi on her. I do an equal amount of city and highway driving and I try really hard to not slam the gas. When I first got my car with 50k miles on it, I was getting about 30mpg.

 

i figured out mine was around 14.5 mpg and every now and then i might take off from a light kinda quick

 

Ya, on average i get 20 mpg around town. I have aLow quailtyebay intake, with a K&N on the end.

 

I am getting about 25 and I do 50/50 driving (highway and city). I am taking a trip to Florida this week from North Carolina, so I will see what I get for all highway. I am hoping for around 30.....

So there is that much increase for a CAI? hmmmm.... maybe this will justify me getting one. I can't believe the price for one in the 3.8 compared to the Z28's and the SS's

 

Yeah make sure your EGR isn't screwed up either... You'd be surprised how much of a difference that little valve can make

 

As evilkal and I have stated your EGR can play a huge role in mileage. Mine was getting about 14mpg with carbon build up in my EGR. Just a good idea to check out.
