Some outboard boat engines and motor cycle engines are (were) 2 cycle with the boat engines maybe upwards of 200 hp. I never owned one but I think they had oil injection which resulted in a sacrificial usage of the oil.

At one time I had a 200 HP outboard, but it used pre-mix. Oil injected outboards came along a bit later but by then I had tired of pouring money into a hole in the water.
