I have a 2000 a4 2.8 quatro automatic with 83k miles.
I usually do either 91 or 93 at exxon or whatever good gas station is there..
I do 95% city driving. NYC.
its all stop and go traffic.Its mostly around 30mph city driving with stop signs and red lights at every block lol..
Add to that I also have a Lead foot and love to accelerate .
I have been getting around 200 miles on my last fillup.

what can i do about this.
new o2 senson? KN air filter?
my tires pressure is around 31 or so..

thanks

 

Dunno, my driving is mainly highway... and USUALLY im babying my car... although once a day I usually end up winding it out... I get about 500 km out of a tank, and I'm in a 1.8T 5 spd. 500 km is around 310 miles... and I'm a 4 cyl, highway driving, 5 spd... you're 200 seems possible for a lead footed city driver, in an automatic v6.

But yeah, the things you said can help with mileage... throw a bottle of fuel SYSTEM cleaner (not injector cleaner, but SYSTEM cleaner) in your gas tank -- Pour in the whole bottle when your tank is nearly empty.. at like 1/8th of a tank (it'll tell you do add to a full tank)... other than that, plugs and wires can help, if yours are original they'd be worth changing.

 

Get a vagcom and check your oxygen sensors.

 

Did you change the spark plugs and air filter at 80K mi.?

 

i changed my spark plugs and wires and noticed an increase in gas mileage. how old are yours? maybe try that, the plugs are cheap but the wires are around 100 bucks.

 

i get about 200 miles per tank on my auto 1.8TQ... in city driving with a lead foot, it gets alot better on the highway
