sounds normal to me.

With headers, lid, and catback mine got 31MPG on the highway.

Now it gets 20 on the highway, and around 15-17 in town.

I don't really care...as long as it runs good, gas mileage makes no difference to me in the T/A.

I have a bone stock 00 WS6, six speed, and I DRIVE it. In town anywhere between 14 and 18 mpg. Straight highway driving I get between 24 and 29 mpg. Sounds like you are doing pretty good to me if all you do is rural roads and in town.

I get 20 in the city and 28 on the highway. 3" exhaust and TransGo. Stock gears on A4.

I am getting between 250-275 miles per tank until the gas light comes on. I am really concerned because I do strictly highway miles, which equals to about 18-20 mpg highway. I have a Corsa catback and a SLP lid. Is there something wrong with my car? How many miles can your TA's go per tank?

I get 140-150 a tank mixed highway/city driving... yea something is wrong with my car. I've done a full tune up(sparks,plugs,fuel filter, pcv valve, change one 02(yes, one 02, my socket doesn't fit on the drivers side,lol). The car still pulls strong. Its completely stock except for a borla exhaust.

weird...everyone is telling you their gas mileage.....try fuel filter..also might be time to change your air filter, o2 sensors..and clean your MAF sensor also.

Good advice there.

Now with that being said. I got 29mpg from here to Saratoga Springs, NY.

Check your alignment and tire pressure if you havent done so already

**cuzimoto** · 11-23-2008, 03:15 PM

Last two tanks both averaged 18.3mpg, mixed driving. Last tank included 4 1/4 mile passes at PSCA, burn outs and cruising the pits. 99 M6, TR224, LT, lid, pullys, free mods, 3.73 rear and 150 wet kit. 11.46 @ 122.

**99formulals1** · 11-23-2008, 04:40 PM

thicker oil in rear end and engine, dirty air filter, tire pressure, larger tires or wheels if there not the same in the two cars, or your driving the new one a little harder to see what its got?? could be a lot of small things. one driven on a warm day and the other on a colder. just my thoughts.

**2001ws6** · 11-23-2008, 10:17 PM

went to atlanta from Cincinnati ...got 25mpg all the way down there.....M6 have borla exhaust cats hooker headers....pretty good i think

**BIG GUNS** · 11-24-2008, 01:36 PM

Well, my T/A does about 19 city and 22 highway under "normal" driving. Of course, I can't resist the occasional squeeze every now and then.

At the track, I normally average about 2.75mpg providing I get about 6-9 runs.

**Too Fast** · 11-24-2008, 01:44 PM

I think maybe your front O2 sensors may be skewed. You said you replaced one O2 sensor? Was it the upstream? Also, like others have said, could be a dirty MAF sensor. I would clean this and change my O2 sensors before changing plugs, wires or fuel filter.

**NJ2002WS.6** · 11-24-2008, 06:29 PM

That is possible. I know my check engine light was on, and they said that it was an o2 sensor. The light went off, so I haven't been worrying about it. If the light goes off, would the sensor still be bad?

yep

**Too Fast** · 11-25-2008, 03:14 AM

Could still be skewed. Not a total failure, but skewed. You should change both upstream O2 sensors when you do. The downstream O2 sensors are only for catalytic converter efficiency, not air/fuel ratio.
