No. Probably. The car will use it's knock sensor to prevent damage,
but the system does have limits. Under certain conditions, pinging
will occur, and damage will result.
But why buy a turbo car if you're not going to run premium? If you've
got the money to buy an Audi, don't have the money to fill it with the
recommended grade of fuel?
You're shopping for the wrong car then. If buying it will cause you such
strain that you will have to buy regular as opposed to premium, then you
cannot afford that car, realistically speaking. I'd hold off until your
income situation improves.
I am thinking of an Audi A4 wagon. Running on 87 Octane (US) without
extra wear will be a requirement. Much of my driving will be commuting
(~50 miles/day) where high octane fuel would be a total waste of money.
I'd only put in higher octane fuel for road trips (1000 - 2000 miles).
Pete is right: my experience is that my gas mileage and car
performance is better with the mfr recommended octane (I run my A4 on
93 octane). This regimen has done my car well for 104,000 miles (98.5
I also concur. My wife has a 2003 GTI with the 1.8T engine (upstate NY).
She usually uses premium, but recently switched to 87 octane gas for a
while as an experiment. The report was that, apart from the performance
change, the gas mileage dropped by about 10%, such that premium was
actually cheaper per mile.
I agree with Pete. My experience with my 3 Audi's (1991 V8 Quattro 5
100S, and 1997 A8) has been higher gas milage with premium.
Another thing to consider here: The difference between 87 octane gas
octane gas is 20 cents. As gas prices go higher, this 20 cent
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
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.
