I'm not going to buy a new air filter for it until i just go all out and get the CAI so if that's it well then that's it. But i am going to start running E85 fuel in it. At $2.89 a gallon as of today, i can't afford regular anymore. Nice thing living in minnesota, we have LOTS of corn to burn. Lol

e-85 is for fuel flex vehicles only, it will corrode your fuel system parts because they are not designed to withstand the high alcohol content in e-85 which will eat right thru them

Well i got money today but gas also went up to 3 dollars a gallon, which means i have enough gas for 10 gallons. That's only a little over a half a tank. That's still not gonna help the mileage tracking... damn.

well, what you could possibly do is run the car out of gas, then put an exact amount of gas in <like 5 gallons or something like that> and then run it out again, and you have your fuel mileage.

Note: i recommend against this whole heartedly because you can quite possibly fry your fuel pump in the process.

It almost is out of gas right now, the needle doesn't even move off of the white line when you turn it on. So maybe i'll try that and get a close estimate. Oh and gas went up to 3.19 today.

but i MUST caution you, you run the risk of destroying your fuel pump in the process.
