> Does two stroke mean it won’t need oil changes? This is not the same kind of two-stroke engine. The one you're thinking of pumps the fuel air mixture through the crankcase, which is why it cannot use the same oiling system that a typical four-stroke engine does. The oil would be diluted with fuel pretty quickly, and also carried into the combustion chamber and burned off. So adding the oil to the fuel is how you get around that, but then you're constantly burning oil.
