Supertech Conc Fuel Injector Cleaner

I went to my Mazda dealer to fix a valve tap. The MX-6 had about 125K at the time. The service manager was an old high school friend and he told me to try this first. I put about a half bottle of it in my crankcase and that fixed the problem PDQ! I still use it occasionally in my fuel system for general injector maintenance. That's usually done in late fall to also remove any water condensation before the really cold weather sets in. Great stuff and about 1/3 to 1/4 what they want for a "Brand Name"!
