Default Bad Gas Mileage??
Well, I'm not sure if it's bad or if it's normal, but I thought I was supposed to be getting around 30mpg on my 01 1.8T A4. I mostly do city driving in Atlanta and I'm getting about 20-22mpg. I have had my 40K service and my throttle body cleaned, but my car just can't seem to get great gas mileage. Can you guys tell me what kind of mileage your getting on your B5's?

Thank you,
GJ

I am getting the same as Dudley. But i heard cleaning your throttle body really does help. So if you have done that you should be fine no?

Man... I can't believe we're not getting better mileage. I just don't understand why they claim these cars get great mileage if they really don't get it in realistic driving conditions. I'd really like to see what kind of mileage everyone else is getting.

old/fouled spark plugs can cause bad mileage, as can a bad O2 sensor...
I get around 26-29 on the highway, and about 23-25 in city driving.
That is in line with what Audi has specified for the car - they never claimed that the A4 gets great mileage.

The dealer replaced the plugs recently at the 40K service, so I doubt that's the problem. Maybe it's a bad 02 sensor. But, wouldn't a check engine light come on for that?

No not necessarily, O2 sensors gradually degrade untill they crap out. I've had good results running Gumout Regain in my gas. Added 50 miles per tank.
