Thanks guys for all the replies! Hell, I have only filled the tank one time and I mixed something like 16 to 1. I think next fill up, I will use closer to 50 to 1. As I said before, I am motor dumb, which would also lead to my being oil/gas mixture dumb. What is TCW-3 all about?? I was told I could just use 2 cycle motor oil???? Also, Could I buy this oil at an auto parts store or do I have to buy it at a marine place? I know you guys willl help me out, so thanks ahead of time!
