Just because you don't premix the oil into the gas doesn't mean that it's not mixed with the fuel before it's injected into the engine. Snowmobiles don't have a wet sump crankcase. All the lubrication comes from the fuel charge injected into the bottom end, lubricating things there before being pumped into the combustion chamber.
