We have had several posts regarding the grade and brand of fuel we all use in our Audi's. So my question is, what do you use and why? Is it the proximity of the station(s) or do you get better performance from one over another? Here's the most popular brands in my area. If I miss any here let me know and I'll modify it.

 

I use Sunoco 93 (APR 93 Program). There is a Shell station 17 miles from me, so when I am in that area, I use V-power.

 

You need to add the option of "I don't care, whatever is cheapest/closest"

 

Cheapest 89 I can find.

 

i use to use sunoco 94 but they stoped selling it so now i use 93. every one in a while i use mobil. i live near boston so i have almost unlimited choices to get gas

 

You know that octane is a little low right?

 

I feel no difference from 93 to 89.

 

The difference may be in your wallet if you continue to use 89

 

the difference in pump gas is all power of suggestion. the 93 octane is not high enough to make a significant hp difference ( 0.5 hp)

 

I run the Sunoco 94. Granted the difference between 93 and 94 is neglidgable, but I prefer it over the 91 that many of the premiums are around here. Today it was $2.26, the same as Shell V-Power down the street and 3 cents cheaper than Amoco premium. I'm lucky that the Sunoco station is kind of off the beaten path so the 94 is less expensive than it would be right off the highway.
