2-stroke engines require that special oil be mixed with petrol in exact quantities. This mixture is added to the engine to provide lubrication. 4-stroke engines use separate compartments for petrol and oil and thus the oil and petrol are not mixed. 2-stroke engines are small and lightweight and are used on hand-held type equipment such as blowers, trimmers, and chainsaws. 4-stroke engines are used on other types of outdoor power equipment such as walk-behind mowers, ride-on mowers etc. Small 2-stroke engines as used on hand-held equipment couldn’t be used on larger equipment because they generally do not provide enough power or torque to turn a lawnmower blade or other device.
