I just recently bought a bottle of Red Line 85+ from the Parts Shop, and would like to know how much to use. The side of the bottle is marked in ounces, but the label doesn't mention how many ounces to use. The label does say for a "cleaning dose" use 12 oz. (whole bottle), but it doesn't list how much to add at each fill up. I thought I read here that some people add an ounce or so at each fill up. I don't need to use it as a "cleaner", since I also bought a bottle of Lubro Moly injector cleaner. Any tips would be appreciated.
