Quattro Gas Guzzler
I had a quick question on a 2001 Audi A4 Quattro, 1.8t, automatic transmission. The on-car display is saying the car averages around 18 mpg. This seems poor, especially considering my dad has a full size 4 x4 Ford Expedition with a 5.4L V8 that averages around 15 mpg.
Is this fuel economy normal, or should I look at doing a good tuneup, such as replacing the o2 sensor?

The car has about 70k miles, and I do mainly city driving with a little freeway, but I did a similar type of driving when I borrowed by dad's Suv, so it's a pretty good comparison. 18 miles a gallon is ridiculous for a modern 4 cylinder compact sedan, so I'm guessing it's time for a new o2 sensor, since to my knowledge it's never been replaced.
