How to Choose the Right Oil for Your Vehicles

Many people often have questions for their mechanics about the best type of oil they should use in their vehicle. One of the most often misunderstood parts of choosing the right type of oil is the number system that is used for rating oils.

The weight of oil, also known as viscosity, refers to the thickness or thinness of the oil. The Society of Automotive Engineers, SAE, establishes temperature requirements for oil. Those temperature requirements range from 0 degrees Fahrenheit (low) to 210 degrees Fahrenheit (high). Oils that meet the low temperature requirements established by the SAE will have a “W” after the viscosity rating. A common example of this would be 10W. Oils that meet higher SAE ratings will not have a letter. For instance, SAE 30.

Special tests are conducted to determine the viscosity of different types of oil. First, it is heated to a specific temperature and then the oil is allowed to flow out of a certain size hole. The viscosity rating of the oil is determined by the amount of time it takes for the oil to flow from the hole. Low-rated oils flow quickly while higher-rated oils flow slowly.

If you’re not certain which type of oil is best for your vehicle, consulting with an experienced auto service center can help you to ensure you are using the best oil to get optimal performance from your vehicle.
