With some city driving and lots of WOTs I get just under 300. I must admit it does pretty dang good.

^^^You've got to be kidding me! I can baby the sh*t outta my car and be lucky to get to the 200 mpt mark. When I drive "normal" I get a consistent 150!

Tried everything too. Tuning leaner, fuel filter, O2's, seafoam, etc...nothing.

Sounds dumb, but I'm actually hoping the new 418 will get better gas mileage somehow...

this is intresting to me, i have 4:10s in a A4 a couple bolt ons and lets just say i dont grandma my car around and i normally see about 200-215 to a tank of gas.

id say put some clean filters in maybe tune up and see if it gets better.

idk maybe im a freak. but i do quite a bit of stop and go traffic and i sit at 3k rpm on the highway a lot in OKC and i thought my mpg was bad guess not

Yea, i know a guy with a mustang and some guys were complaining about gas mileage and saying yea you get 200 to a tank. I was like more like 3-400. And of course they say...yea bullshit. I'm like, ok whatever, I don't gotta prove anything to your ignorant ***. Cuz I've gotten 27 on a small road trip, mostly highway, some city. Not sure of our tank size, but if it's 15: 15*27= 405 miles. Yea so suck that, f*ckin mustangs...

IDK why some of you get such terrible mileage.

I dont feel so bad after reading some of your mpgs

I average around 13-15mpg of mixed city and highway driving (spirited of course)

mods are in my sig

So I guess I would knock down 225 or so a tank full

Man i dont know sounds like you are getting way too low of miles per tank. I have a 99 trans am with free mods and 4.10's in the rear and its a stock A4. I dont think i have every got under 275 miles on a whole tank i average around 325-350 depending on how im driving but i will tell you i dont take it easy and im 90% city driving. It has 165,000 miles on it original motor and all. I would give yours a tune-up and maybe check into couple other things. The best i did on a complete tank with my stock gears was 415 too the tank. I have a 16.8 gallon tank in mine. Hope this helps. any questions my email is ramair1999@hotmail.com

I get in between 260 to 275 in the city with a few wot runs. I get about 365 on highway trips. I guess I have an efficient engine with most bolt-ons. A tune goes a long way with a bolt-on engine.

I have the A4 trans, 2800 torque converter, free mods, full exhaust, stock 3:23 gears, and dyno tune. It also helps to keep the rpm's under 2000 when not accelerating wot.

you guys ever heard of factory freaks? those are the ones way faster. you can also tell by the shitty gas mileage they get, even as maintained as i keep mine.

As a bolt on car my T/A would get 23.5 mpg or about 345-360 miles a per tank taking 14.5 to 15 gallons of gas to fill up. That was my normal driving. On trips the car would get 30+ mpg. Best ever was 32.8 mpg. Worst was the first tank of gas when the car got 16 mpg.

With H&C, the car gets ~20.5-21.5 mpg, best is 28 mpg highway.

M6, stock rear, 512 rwhp with an aggressive H/C package...still gets 20.2 mpg.

They are more of a myth then anything, usually generated by high reading dynos.
