What type of gas?
I just bought my A4 yesterday and I need to get some gas soon. What kind of gas should I use? I know it suggests you use premium, but is that necessary? Will plus or regular work just as good?
Thanks

It will work but it might cause damage to your engine. The engine has a low compression ratio because of the turbo and 87 octane will not burn as well. I have an '01 S4.

I HIGHLY SUGGEST 91 octane or higher. (look at the inside of your fuel door). Even the tiny smart takes premium.
Not using premium can cause turbo damage which is very expensive.

Premium is necessary. Plain and simple. It's not a suggestion nor is it some kind of "maybe." You risk seriously damaging several engine internals by using just one tank of plus or regular gasoline.
Plus, what've you got to worry about? You just got an A4 and the premium gas gets you better mileage than the others.

Whenever you have a turbocharger its a good idea to use premium gas. Especially if you bought it used and the previous owner used premium, its not a good idea to witch to regular.

MY OPINION... ALWAYS THE BEST ... but maybe for that year i assume that they will told you , premium.. so i guess by now could be de middle one.. but even that i will go witth premium

Premium for sure. I have a 98. The engine will knock if you use less octane... It won't get you hardly any better mileage but you still need it.

Use what ever it says on your book or gas cap. Your car is programed to burn a certain octane. If its meant to burn 87 then put 87. Since it is a turbo vehicle you will probably be using 91-93 octane for the slower burning fuel which reduces your chance of knocking.

A4's are made to run on premiums only, any other type of fuel hinders their performance.

definately go with the higher octane. the higher octane fuel burns much better than the others. the higher octane will keep your engine much happier and increase performance of your ride even though its more, ALOT more expensive

Premium only, any thing else will cause damage to both the engine and turbo.

Hi-test, 93 octane is all I used when I owned mine. Used 89 once and i noticed a lag, idk if you will with 91, but the 93 for me worked great, and do not use fuel additives, they are a waste and actually corrode your gas tank

Premium is the only way to go. Without the high octane rating, you risk knocking and damaging your sparkplugs, especially since it's the turbo'd version.
