Good point regarding detergent, Nick.
So, what supplier's got the most effective detergent in their gasoline?
Are Shell and Chevron best?

Can't help but give my 5 cents here...I've pretty much run 91 in both my
Audi's with exception to a couple of 89 fillups a few times without noticing
much difference, if any. I try and use the good stuff, i.e.Shell, Chevron
etc...a decent detergent based fuel to keep the valves clean (this does make
a difference). Most gas stations appear to only have two tanks, the 87 and
the 91, the 89 coming from a mix of the two at the pump (hence probably
contains some of the detergent from the high grade too - if you don't
believe me see how many gallon counters there are on the pump you're
using..only 2 for 3 different grades...), so 89 is probably just as good as
the 91 with a little retardation from the ECU. If you're using a chip, then
89 seems a little backwards, but if it's regular driving you're probably OK.
Like Rocky, I try and stick to what Audi says because they warranty the
vehicle and know more about them than anybody else and to be honest, are you
really saving that much money in the long run?
regards to all,
