I use Shell or BP. After years of using premium, these seem to work the best. You notice it more on turbo cars when you get spark knock (detonation). As far as injector cleaners, BG 44K is the only one that works. Seafoam and all the other stuff is junk. Doesn't work. Octane boosters are worthless. Just my .02.
