The Vespa that my uncle used to have had a measuring cup built in to the underside of the fuel cap. He would fill up the cup with pre-mix, dump it into the fuel tank, then fill up the fuel tank with gas. He would then shake and bounce the Vespa around (it looked really funny!) to mix it up good before starting the engine.
Perhaps you could do something similar only have it with some sort cap on the cup to seal in the oil until needed.
