I tried the SuperTech TCW3 in 3 of my vehicles and didn't like it. I was doing the 1oz to 5 gal. Maybe I was using too much? But that was the recommendation on the inter web. Using the remainder in my OPE just to use it up. I notice a funny smell in the OPE. Maybe I'll give the remainder to my son who has an outboard.
I'd only use it in a Mazda rotary .
