Don't be so sure. Check your fuel consumption. You might just find
out
that you get better mileage on 91+ octane.

I agree with Pete. My experience with my 3 Audi's (1991 V8 Quattro 5
speed, 1992 100S, and 1997 A8) has been higher gas milage with premium.


Another thing to consider here: The difference between 87 octane gas
and 93 octane gas is 20 cents. As gas prices go higher, this 20 cent
difference decreases percentage-wise, making the premium gas a better
value as the gas prices go higher, assuming that your car gets 5% - 10%
better milage with premium as I have experienced. You also get better
performance and less wear on the engine.

Exactly! My wife drives a Lexus RX330 and I told her to use 87 or 89
octane. She drives about 40 miles/day with it. Having nothing better
to do, she experimented with three different octanes (she has a PhD in
physics, so this is her nature d;o) ). She got much better mileage
with the 92 octane and insists that the few extra pennies a gallon is
worth it in mileage.
