The first number in the oil classification refers to a cold weather viscosity. The lower this number is, the less viscous your oil will be at low temperatures. For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil. 5w30 is for cold weather, the letters and number mean the weight of the oil 5 is lighter than 10 therefore 5w30 should be ran in weather below 30 degrees it can circulate better and your car will start better. 10w30 is for hotter weather so it keeps the engine cooler.
