Understanding Motor Oil Types

Motor oil is the lifeblood of any vehicle and provides lubrication for the moving parts in your engine. It’s extremely important to have your oil changed on a regular basis in order to maintain a healthy car. With several different oil types available, how do you know which one will work for your car’s needs? Read on to learn more about the different types of oil and what they mean for you.


All motor oil comes with a grade that is assigned by the Society of Automotive Engineers, or SAE. This number can reach as high as 70 and the higher the grade number, the higher the viscosity of the oil. You may also see a number listed as “weight” on the packaging which is the same thing as the grade. Anything behind the grade number with the letter W means that the oil meets low-temperature requirements. Some of the most common weights include 5W-30 and 10W-20 to name a few. Be sure to check your owner’s manual where you can find more about the proper oil grade and weight for your vehicle.

Viscosity Levels

Older cars require oil that is thicker in consistency to provide the engine with additional lubrication. As engine parts wear down, it increases the amount of friction. Thicker motor oil can help to condition the seals in older cars. It’s important to note that the thickness of your oil will likely change depending on the temperature, too. Warmer temps mean thinner oil, and colder temps mean thicker oil. The viscosity level is factored into determining which oil will work best for your vehicle. Thin viscosity won’t work as well in older engines. Try an all-purpose motor oil that works well at several temperature levels to ensure every part is properly lubricated.

Oil Types

The three main types of motor oil include conventional synthetic and a synthetic blend. While synthetic oil is typically more expensive, it’s usually recommended for most vehicles. You can also use a synthetic blend that combines both conventional and synthetic oils together. When in doubt, refer to your owner’s manual or your mechanic. They should know which type of motor oil will be best for your car based on the make, model, age, and more. The best rule of thumb is to use thicker oil if you drive an older vehicle.
