I use jet fuel and it works great. Kinda expensive though.

 

I dont want to deal with regular again. A lot of problems and malfunctions of the fuel burning systems.

 

yopu'll probably get proportionally more gas mileage to the increase in price anyways, you get performance and more mileage.

 

I've put nearly 300,000 miles total on 2 Audis ('98 A6 2.8, '03 A4 1.8T) in the past 7 years. Never ever use anything but premium, preferably 93 octane!!!

 

i never read anything telling me what i should put in my car. franlky, i don't care. Its 93 octane always for me. I'll get over the extra $3 OF DEATH that it costs me a week to do this.

 

WORD.

 

Funny you mention that- my father is an aircraft mechanic and brings home jet fuel which has been drained from the wings (you can't reuse it by law) and heats his house with it in the winter. No problems and he's been doing it for 7 years!

 

eek i been putting 89 in my tank ;(

sorry i have no clue on why 93 or 91 would be better than 89 or even 87

im a retard, can someone explain more?

 

Wikipedia is my favorite: http://en.wikipedia.org/wiki/Octane_rating

Audis engines were designed for higher-octane fuels.

 

i have a 99 audi A4 2.8 V6 and i always put in preium 93 Octane whats the extra 10-15 cents man. - Cp-
