decrease in gas mileage in 1999 2.8 A6 quattro
I have already addressed the following:
-air filter
-tire pressure
This is according to the the computer, but I have done 450 miles on a tank and this is on a 2000 with 97k on the clock.
I always though the 2.8 was just close to the 2.4 on fuel consumption ..... maybe not !?
If you're only getting 250 miles out of a full tank then the O2 definately sound suspect - My wife gets 238 out of an old Jeep Cherokee 4ltr with a smalley gas tank then the A6.....and I thought that was bad!
