Fuel type
 

I'm looking at buying a 02-04 A6. Do any of the available engines require
that you run premium fuel?
Thanks, K

Re: Fuel type
 

Yes, but if you run regular the engine will adapt in normal driving and
the give up will be performance and according to conventional wisdome,
mileage will be poorer.

If you drive your car more aggressively you would need to go with 93 or
at least 91 octane (US Octane rating).

I have previously owned a '98 1.8 TQM (APR chipped stage 1) and
currently have an '04 1.8 TQ6M. The I kept the '98 to 95K miles and
currently have 68K on the '04. I have used 91 octane in the city and 89
on the highway. I have also compared highway mileage over many tanks (I
dive on the road a lot) on both grades and if anything it seems that
mileage is better by 4 or 5 percent on the 89 octane. Go figure.

I'm getting ready to put on my flack vest after that comment.

The engine management including knock sensors and O2 seem to handle my
driving and fuel choices quite well.

My 2007 A3 3.2 also runs fine on lower octane gas for mild driving.
Freeway cruising gives exactly the same milage. I think I felt a loss
of responsiveness.

The type of engine and climate probably matters a lot. The A3 3.2
doesn't have a turbo, a high compression ratio, or any exotic designs
that would require high octane gas. Except for that intake comb-over,
it seems like a pretty boring engine.

As long as the engine is non-turbo, you should have no problems
burning 89 octane. The car will adjust to the type of gas you choose
to buy. You will probably experience less than the maximum
performance level of the engine, however, with a lower octane. I have
put 89 octane in my RS6 (V8 with twin turbos) and it ran just fine. I
did notice a decline in performance, but that was because of how I
drive. d;o)
