[s-cars] Lowest octane for road trip?

[Tom Green]

How many tankfuls are you looking at, Mike?  I think a couple of bucks 
is
about right.  Now, 91 octane is the lowest Audi recommends, and also
happens to be what many less fortunate listers have to live with 
everyday,
since it is the highest octane available at western US stations, 
especially
when the reformulated summer gas arrives.
Shouldn't give you a problem unless you are running some software that
was designed for 93 octane and maybe a knock sensor is inop or slow to
respond.
