I have a 2002 a4 ws6 trans am and I while back I filled it up to see what my mpg was. I got 20mpg in the city then when I went on a trip I got 20 mpg on the highway. By the way I didn't floor it any when I drove around the city and I stayed the speed limit.

Doing the speed limit I've seen 25-26 hwy and 18-19 city. That was with stock gearing and a M6 though.

havent been on a trip for a long time in my car.

i was gettin about 22 mpg around town before i did the heads/cam swap. now i get about 19mpg around town. no real highway driving for me, though I'd assme it would get better with the 6spd.

once i get 3.7 gears i'm hoping the mileage will go up a little bit!

my old heads/cam/3.73 gear 400 rwhp camaro would get 30mpg on the highway and 22-24 around town. not really sure why but i calculated it plenty of times and the speedo was calibrated (GPS varified my speed many many times).

Hi all, I get 20 mpg in the city taking it easy. I drove from Toledo Ohio to Buffalo ny and got 29 mpg. I have 2.73's thank god! My buddy has 98 a4 2.73 convertible and drove from Nashville to home in Buffalo and got same results.

Please don't believe a many of these people. I have seen many a people claim to get 30-35mpg with a 408ci engine putting down 500whp.

i have a 2002 z28 m6 w/all the boltons, heads/cam dynotune blah blah blah.... my real milage around town is about 12 mpg when im taking it easy! my came specs are 238/240 604/609 112 and that may be a big part of it, rwhp is around 425. i see alot of posts saying they have 500hp and get 20 mpg around town, i dont see how!

whats your gears? if you have really low gears it'll hurt gas mileage. also depends on auto or manual. i have a great tune, only thing i can think of that would help my gas mileage so much

I get 26 highway with the non lockup convertor, and about 17 in stop and go traffic. Mixed driving my average is between 18 and 23 mpg, depending on traffic and such

I drove my heads/cam/4.10 geared car on a trip this past spring. Running the a/c, and with some hills, driving between 75-80, it got 24.86 mpg. Just out messing around, it's only got under 20 ONCE, and that was like 19 mpg. I'm satisfied

I'm in the doubting Thomas camp. I see & hear the claims of 18 city & 29 highway, but I've never ever ever had a whif of that. My 2002 convertible M6 on 93 octane is 14 around town and 20-22 on the highway. No difference before heads/cam or after tune or after going from 3.42 to 4.11, or after the Kooks, or after the high flow cats or after the high flow cat back, or after the SLP lid, or new o2 sensors. Nothing has affected the mileage I get. Well, if I drive hard on a tank it drops to 10-12.
