I do know that from talking to my uncle that uses the amount I used; he uses TCW3 in his 98' metro hatchback and his 92' s-10 V-6 and says that he had some cheap junk gas few times before using it, and that now with the TCW3 in the tank, the white scum and gunk is gone. He pulled his injectors out of his truck after cleaning them and before the 2 stroke oil, and since using the two stroke oil, and checking the injectors again and the screens he said they are real clean looking.
