It's kind of an orthogonal issue. Oil is needed in the fuel for two-strokers with crankcase ventilation for lubrication. Lead is needed to boost octane. But your old outboard engine is most likely a very simple low compression engine that doesn't need particularly high octane, so can run just fine on regular car gasoline (preferably without ethanol, but again a slightly different issue) mixed with the two-stroke lubricating oil.

Before unleaded automotive gasoline became the norm, all kinds of 2-stroke engines ran on leaded gasoline just fine.
