5W30 Oil is a multi-grade oil. Multigrade motor oil flows well in cold temperatures and still protects the engine at hotter temps. Oils have high viscosity when cold and a lower viscosity once the engine has reached its operating temperature. This difference is too large for most single-grade oil. In order to bring the difference in viscosities closer together polymer additives are added to the oil. The result is a multi-grade oil.
The first number in your oil (5) is the viscosity grade cold. The second number (30) is what you will have when hot (212 degrees F). A 5W30 Oil must pass the SAE-J300 viscosity grade requirement for both 5W and 30. The W stands for Winter, meaning your oil is good for year round driving.
