is it just a detergant thing or what? I ask because universal is generally found it quarts but outboard is easily found in gallons, which would be nice to carry around for mixing my diesel fuel with.

I believe two stroke oil is two stroke oil. Some outboard motor companies, for example, mercury and evinrude/johnson put extra additives in their oil for their specific needs. That is why you pay more for the engine specific name brands. The only thing that matters is the ratio that you mix it at, like 50 to 1 or 25 to 1 etc. Also the fact that it meets the TCW-3 spec.

They now have fully synthetic 2 stroke oil. I guess for the same reasons that we use synthetic engine oil. It is much more expensive!
