When you're browsing the selections of motor oil available during an oil change or while shopping in the store, you may wonder what the numbers on the front of the bottle indicate. These numbers, like 5W-30, indicate the viscosity of the oil or its resistance to flowing easily.
The viscosity of oil varies according to its operating temperature, and the effectiveness does as well. Low viscosity ratings are a great choice for cold temperatures as they help your car to get going, while high ratings help to indicate an oil that protects your engine parts in hot temperatures. The lower number in the rating indicates the viscosity in cold conditions and the higher in hot conditions.
