Wasting money. Some guys do the same thing with diesel to clean things out too (which makes a bit more sense as it actually burns hotter - I still wouldn't recommend it). Depends on the car, but on newer vehicles, some actually perform worse with premium fuel, depending how the OBC is mapped. Follow your manual's guidelines on what grade of fuel it recommends. If it's premium, use premium. If it's regular, use regular. If it suggests either (or higher), you're always better off with the higher octane content (used regularly, not every 6 months). Toss in some seafoam every other oil change to keep things clean.
