Thanks for the links. I always figured it was a type of "Top Oil" as stated above. I used it every tank in my first gens.
I've also considered using AMSOIL 2 cycle lube. That stuff is just a miracle cure for 2 cycle engines. I used to have to rebuild the (3) carbs in my outboard every 2 years. When I switched from dino 2-cycle to Amsoil, never had to do it again. Stuff burns very clean and it a strong detergent. I'm just not sure of the effect on the catalytic converter and all.
My theory has always been that you can never have too much lubrication.
At least when it comes to car motors.
