I've been looking at 2004 and newer GPs online. In many of the ads, I've seen Grand Prix GTs shown specifying that premium fuel is required. As far as I can tell from the ads, they are just a standard series III 3800. Is higher octane required for these engines?

Unless they are supercharged I dont believe you need to run anything higher than 87/89?
