The Importance of Using the Correct Motor Oil

The Importance of Using the Correct Motor Oil

Motor oil is often referred to as the lifeblood of our vehicles. It performs many important functions.

• It acts as a lubricant for the engine parts.
• It helps protect the emission system.
• It provides enhanced fuel economy.

If you’ve ever taken the time to peruse the array of oils available today at an auto supply store, it can be overwhelming, and if you choose the wrong oil, it can have consequences. It can even damage your car’s engine over time. If you are a person who changes their own oil, always check your owner’s manual before you proceed and make sure you have purchased the correct oil for your particular type of vehicle.

There are three types of motor oil:

• Conventional (75 – 80% of refined crude oil)
• Full Synthetic (Standard base plus additives)
• Synthetic Blend (Conventional and Synthetic)

Then there are additives, such as detergents to keep the high-temperature surfaces clean and antioxidants that prevent oxidation and keep the engine oil from thickening. Additives also capture dirt and other contaminants to prevent build up on engine parts. There are even special oils just for high-mileage vehicles that have a conditioning component for the seals to prevent leakage.

The American Petroleum Institute classifies motor oil by viscosity. Using the correct viscosity of oil is vitally important to get the most benefit for your engine type. Viscosity refers to the motor oil’s weight, and on the container, “W” stands for weight. If you live in a warmer climate, you will need different weight oil than those living in colder climates.

Motor oil is and has always been the life blood of your vehicle’s engine. Getting the correct oil is crucial to keep your vehicle’s engine running well for years to come. When we service your vehicle, you can rest assured that we always use the correct oil.
