WhtA6

Getting 14.8 in city driving. Mostly stop and go. My wife, a very passive non-aggressive driver, drives car 90% of time. Car just had 30k service. Is this the norm? Would a higher octane fuel help? Can get 100, but I don't think the price of the gas would lead to lower gas costs because it is $3.90 per gallon! Maybe I could just put in 2 gallons per tankful? What do you all think?

Higher octane has nothing to do with gas mileage, and won't help. I get 20-21mpg commuting.

Only keeping the garage door off the hood can help. Ooops, too late. (Sorry, that is a bummer).

The A6 is a thirsty vehicle. High octane will do nothing for you. If fuel economy is important, maybe one of those Toyota hybrids is the ticket.

Be glad you don't have a 2.7T.... with a 2.8 you have 'dreamt of gpg' from some of us 2.7T owners

I thought high octane had lower energy density but is easier to burn. Your car is a gas pig.

That's why you have to use it in the turbo engine, otherwise there would be so much detonation you wouldn't be able to go anywhere

A trip to Clarksville, Tn from south Georgia netted me an average of only 22.9. VW/Audi cars don't typically get the posted sticker mileage.

What oil are you running? Could have a small impact on gas mileage.

but that was in my Nova. I average 18 in the city and near 25 on the highway. I always use premium and 10w30 Mobil 1 full synthetic. I've gone as low as 16mpg in heavy traffic driving.
