a friend of mine is thinking about buying a new forester. he was looking at the turbo model. they salesman told him you can only run premium gas in it or it could do somthing to the turbo and the warranty won't cover it, anyone know anything about this.

Yes the turbo engines require premium fuel and there probably is some language in the owners manual about risking the warranty if you run regular. You also are supposed to knock your oil changes down from 3500 miles plus to 2500 mile intervals.

 

My experience with the Subaru turbos of the 80s is that the engine would surge if I put regular gas in. Steady high rev output requires premium fuel.
