The "W" stands for weight. The "W" stands for winter. 5w30 is a multi viscosity oil. It acts like both 30 weight in warm weather, and 5 weight oil in cold weather.
If you mean W as in 10W30 motor oil, it stands for Winter. The thickness of those oil changes with the temperature- they are not as thick (viscous) in cold weather, but get thicker as they warm up. Makes it easier to start the engine in cold weather.
