The numbers 20W50 refer to the viscosity of the motor oil, set by the Society of American Engineers. This refers to its fluidity or thickness. The "20W" indicates how quickly the engine will start when cold or in cold weather. The "50" refers to the thickness of the oil when the motor has been running for a while.
