Ok, it's probably been asked but as Top Tier Gas has growing list of Brands now and some time has past, Is top tier gas really worth it? If BMW, Toyota, GM and Honda (there are more) all say it's better, then it must be? I've been using Top Tier for years and never use or needed to use any cleaners. Now that a lot of autos are GDI, I here top tier is even more important. So is it smart, or a total waste of money to run these Top Tier Branded Fuels?
