Those of you with intake, 93 oct tune, and 20"ers...
how many miles are you guys getting to the tank before its time to fill up again?...
im only pulling in the 280's-290's....when i had my 17"ers on, i was getting in the 320's....
i drive conservatively as well.....
do the wheels hurt us that bad?

Hopefully you've adjusted your speedo for the new tire diameter and have your tire pressure where it should be. I can't speak in terms of "per tank" since I speak in terms of MPG. And since nobody runs their tank empty, miles per tank to me is a useless method for comparison.

Is this for a GT? If so, I'm not getting anything near those numbers.

i usually average about 260 per tank, but it didnt really change with the 20's. i even do a good amount of highway driving now too. kinda sucks. i did however average about 25-26MPG on a hwy trip to FL over the summer on my 17's.honestly, mine dont weight much more than stock 17's(shelby forged 3 peice 10.5 rear

I'm getting about 17-19mpg right now. New 20's and I just started running 93 since gas is so cheap. I guess that would yeild about ~270 miles before I went to fill up. I've been doing a lot more city driving though so I think that's hurting me as well. I haven't bothered with adjusting my speedo cause my tires are .1" larger than stock. No big deal.

how do you adjust the speedometer for wheel size? is it something we can do on our own in the driveway or do you have to take it somewhere?...i would say my average is 18 mpg...the estimated Miles To E on the digital scereen is iffy though....right when you fill up it'll say something like 319 Miles To E but then when you are pretty much done with the tank and running on fumes to the gas station, you look at the trip meter and its at 268 lol.....well all in all from seeing the recent posts, i guess it could be worse!
