People in the US seem to think that if they can't get two strokes, NOBODY can get two strokes. That is totally wrong. The EPA and the US government are the reason you can't buy two strokes in the US. For the rest of the world, they are preferred in many places. Its simplicity and power to weight ratio vs a four stroke's less noise and slightly better fuel economy under some conditions. Four strokes are more expensive to purchase, more expensive to maintain, and heavier for the same horsepower.
Wonder how much more energy and chemicals it takes to manufacture all the additional parts in a four stroke, and the spares for them.
As for the fuel and oil questions, both two and four strokes use fuel and oil. The two stroke gets some power from the oil. The four stroke oil gets discarded, somewhere.
