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.

Recently picked up a gallon of Supertech outboard motor oil from Walmart. It states that it's meets requirements of Outboard motors, chainsaws, weedeaters, 2 stroke mowers and other 2 stroke equip. Can be used in Injection or pre mix systems. It also meets the TCW-3 spec which is the good stuff. Can't remember the exact price but it was a little over $8 a gallon.

I dont know how it afects us useing it as a fuel suplement, but it will ruin a 2 stroke moter if used wrong. You can use non outboard oil in an outboard,but you cant run outboard oil in a 2 stroke motor. Like a chainsaw or lawnmower. Hope this helps. Rod
My Husqvarna saw seized a ring due to using TCW-3. If you don't believe it; go ahead and use it in your $800 saw. TCW-3 should only be used for liquid cooled applications regardless of what the jug says.
