Won't hurt. But to be honest I'm not sure everyone buys into the "Top Tier" fuels anyways. All fuel is required to have a certain amount additives. Do the Top Tier gasolines really have the "Ultra Nitro Plus Super Mega Power" additives? Or do they just have what is required and call them something fancy?
Either way...using it more often that once per oil change won't hurt a thing. If it gives you peace of mind keep doing it. If you want to save a few bucks, do one per oil change.
