What do you want the additive to do? I presume it is more than just keep the gasoline fresh?

if you're looking for an additive to increase the life of the fuel. the 2-stroke oil does that - it adds the carbon backbone molecules needed for the fuel to not break down as quickly. however fuel will still go bad eventually

if your looking for an additive to lubricate the engine, the 2-stroke oil does that.

if you are looking for an additive that does some miracle thing, it doesn't exist.
if you are looking for an additive that cleans your fuel system, it doesn't exist

there is no mechanic in a can

therefore the only and I repeat the only additive you need for a pre-mix 2-stroke fuel is the 2-stroke oil.

And run fresh fuel on each outing with no product whatsoever added to the fuel besides 2 strokes oil...

Happy Boating
