Super Tech ???
Bob: I haven't used the anti-freeze, but I have used the oil treatment. Our push mower developed a rod knock two years ago. I filled up the mower with 3/4 of the sludge to 1/4 30 wt. oil. Although the knock didn't go totally away, I still was able to use the mower for two years. STP probably would have done the same.
When any product has the name SUPER it better perform, above and beyond.
