Hi,I have a Wizard wf4 Super Twin and am finally going to use it. I was told 16 to 1 gas ratio was correct, but also told to use regular 30 weight oil, not marine oil. Is this correct? THANKS.
The original spec was non-detergent 30wt oil. Although correct, it will carbon up your motor over time. Modern TCW3 oil is more than fine to be using on a motor of that vintage, and that is what I would recommend using.
