Well im curious, how many miles is everyone getting per tank? I am getting about 240-260(17mpg). I hear some people get around 21 mpg on city driving and I'm wondering how?. I tried to get better fuel management by adding a CAI and tuner but that didnt really help and im still getting about 17mpg in the city and dont really drive my car too hard. What is everyone getting per tank and what have you done or doing to get better gas mileage?

i was getting about 17/18 with a little highway, got my tuner and i've been getting 19.5 on the performance tune from AM. and i'm the opposite of going easy on it lol. My dad said it best if you are getting a performance tune to get more power and you can only get good gas mileage if you drive easy then why get a tune?

I'm getting 20-21 in the city and I think 27-28 on the highway. Haven't checked on that but the only mod that I have is the K&N air filter. I also let off the gas a lot to conserve fuel.

Overall, I get about 21-23 per tank which equals about 325-350 miles for 15 gallons.

I have a CAI and 87 octane performance tune currently installed.

93 Race Tune/JLT average 22mpg 70%city/30%highway Driving like I stole it!

Before the CAI/Tune close to 18/19 also driven like I stole it. Highway was closer to 28/30 mpg. But havn't been on any long trips in a while.

I am running a 91 octane performance tune and get 24 mpg average. Its difficult to drive moderately with a manual transmission, your right foot and right arm develop a life of their own.

That doesn't sound right. Have you changed your fuel filter lately?

I didn't see your car was a '09 but around every 30k. Can't be that dirty yet

fuel filter change is every 30k, stock air filter should be changed at 15,000 or good idea to clean CAI filters too every 15,000
