the best i ever seen in my 99 a4 ss with longtubes, ory, slp lm 1 and a lid was about 310 on a full tank without getting on it at all..didnt get above 2k rpm the whole time. my 89 honda will get about 350 or so on a 10.9 gallon tank:]

my bro has a mild H/C 400 rwhp formula 6 spd and drives about 240-50 miles between fill ups, but he drives it like a grandma though. Thats better than what i used to get with my stock 02 t/a lol, but i cant resist from not going WOT about 10 times a day on average

My 94 Z gets about 350 on the highway, and about 280ish city driving. and she is got a miss now for some dumb reason, but is all meaningless while it's in the body shop (******* snow)

I have got this before when I went to work in Ohio but had to fill up before I got there cause I wanted to see what I could get with my car compared to a dually so I set my trip to check the miles and I think it was close to 415-420 before I pulled over to fill up because I had never been there before and didn't want to take a chance on me not finding another gas station cause I was sucking the bottom of the gas tank out, lol.

Just a thought...but I was getting 180 mpt, then my fuel pump assembly died. I ran my current tank down to the needle on empty so when I pulled the tank to change the assembly it would be empty and easier to drop. Turns out I still had about a quarter tank left of fuel. After installing the new assembly and hooking the tank back up, my fuel gauge showed over a quarter tank of fuel left. Something with the assembly, probably the float, was messed up and giving me much lower fuel readings then what I really had left. Just some food for thought. I now get upwards of 250 a tank

[QUOTE=Ruthless909;14357394]Makes me kinda miss my 07 Civic SI [QUOTE]
Yea, our 07' Civic SI routinely gets 41mpg if you don't go faster than 70mph on the hwy.
My Full bolt on Trans Am (minus UD Pulley)/ and Tune gets 31mpg on the hwy. Went about 204 miles with 6.5 gallons. And that's not going faster than 70mph as well.

I get worse gas mileage with 93 in my motor - anything under ~10:1 compression isn't really going to benefit from crazy high octane. I'm at 9.6:1 and I think my performance even improved when I went to 87.
And, for some unexplainable reason, my wallet has been getting fatter.

I am running a pretty much bone-stock '99 Z28 M6 with about 84K on it. The only mods are a lid, FTRA, and K&N filter, which is in need of being cleaned/replaced. With mainly city driving, I'm consistently getting just over 20mpg (between 20.2 and 21.3 over 6K miles in 2010).

Wow thats awful. I have an 04 GTO M6 with K&N CAI and I have a 16 gallon tank as I suppose all of you do. I get about 290 miles per tank in town I believe and on high way I've got 400 miles or so per tank w/cruise @72mph. And that is on 87 octane. When I have 93oct in my car I usually am planning on thrashing on it, but from what I've observed lol and hard to believe that even under normal driving I get WORSE gas mileage when I run 93oct.
my 99Z28 stock auto w/2.73's i had 350/360 miles on a tank
