Car Forum / Audi Cars / November 2006Damage from Regular Gas
I wonder if it's harmful to use regular instead of premium fuel in a turbo engine? wrenden > I wonder if it's harmful to use regular instead of premium fuel in a > turbo engine? 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. Regards, Pete > >> I wonder if it's harmful to use regular instead of premium fuel in a > >> turbo engine? [quoted text clipped - 14 lines] > > brody 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). > I am thinking of an Audi A4 wagon. Running on 87 Octane (US) without > extra wear will be a requirement.

You might just find out that you get better mileage on 91+ octane. Pete >> I am thinking of an Audi A4 wagon. Running on 87 Octane (US) without >> extra wear will be a requirement.

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 A4 2.8Q). > >> I am thinking of an Audi A4 wagon. Running on 87 Octane (US) without > >> extra wear will be a requirement.

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. -steve Pete Wrote: > "Kevin McMurtrie" wrote- > I am thinking of an Audi A4 wagon.

My experience with my 3 Audi's (1991 V8 Quattro speed, 1992 100S, and 1997 A8) has been higher gas milage with premium Another thing to consider here: The difference between 87 octane ga and 93 octane gas is 20 cents. As gas prices go higher, this 20 cen difference decreases percentage-wise, making the premium gas a bette 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 bette performance and less wear on the engine -- berniepet >> I am thinking of an Audi A4 wagon. Running on 87 Octane (US) without >> extra wear will be a requirement.

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.
