Re: WHY Low Octane???

Interestingly enough, the dealer from whom I purchased my '97 A4Q told
me repeatedly that I didn't have to use anything above 87 octane.  Even
to the point of saying "You don't believe me, do you?" -- to which I
said "Nope".

Still trying to figure out why he was so persistent...

'97 A4Q - both on 93 octane, thank you.
