What kind of oil does a two stroke motorcycle use?
The ratio a rider should use in his two-stroke will depend on the size of the machine and the type of riding being done. An 80cc racer will require much more oil in the mix than a 500cc play bike. The best bet is to consult the owner’s manual and follow the advice of the engineers who designed the motorcycle.

The exhaust of an outboard motor goes directly into the water, and environmentalists are worried about the oil in the mix polluting the lakes and rivers.
