I am confused as to what is the proper octane rating for the 2.0 turbo Atlas. The official advertisement from VW states tha engine makes 235HP but in the small print states that the 235hp is achieved using premium fuel. Now, my dealer says to use regular. According to VW.com specs of the engine, it also says regular unleaded. Now, what sort of missadvertising is that? 235hp, but use regular, which would obviously reduce the engine’s power down from 235. I always knew that the GTI’s 2.0 turbo engines needed premium, even when I test drove one in the past, the dealer said it needed premium. The Atlas’s 2.0 is the GTI’s engine. I looked the current specs on the current GTI model and according to VW.com GTI uses regular gas! Since when does the GTI’s 2.0 use regular gas? Is this in error? I am totally confused as to what is proper fuel for the 2.0 atlas. It seems none of the current VW cars need premium!??! But they advertise the HP using premium fuel.
