Did you know that some of the moving parts within your engine never really touch? It is true! They ride on a thin film of oil. One of the main functions of oil is to keep these moving parts separated from each other, preventing damage and wear.
Another important function of oil is cooling. As the oil circulates it carries away some of the heat generated as a result of the combustion process. When your motor oil level is low it will cause the engine temperature to rise. It is important to check your motor oil level frequently to make sure that this doesn’t occur.
Did you know that motor oil also plays an important role in helping to keep your engine clean? The oil within your engine is constantly cleaning as it lubricates picking-up and holding dirt, contaminants and other combustion by-products. Think of motor oil like you would think of a sponge. We all know that a sponge has the ability to pick-up and hold fluids, dirt, etc. When a sponge becomes oversaturated it can no longer hold any more fluid. These same attributes apply to your motor oil. When the oil becomes saturated with contaminants, and cannot hold anymore in suspension, the excess falls-out of suspension and can form deposits in the engine, one of which is known as “sludge.” Regular oil changes will remove suspended contaminants before “sludge” can form, helping keep your engine running cleaner and smoother.
You want to get your oil changed before sludge starts to form. Remember, sludge is one of the top enemies of your engine, so you want to take action before sludge takes over. The timing of oil changes can vary depending on the type of vehicle you drive, where you drive, and how you drive. Your vehicle manufacturer has done rigorous testing to help determine the timing between oil changes and the proper oil. All of this information can be found in your vehicle owner’s manual or you can easily stop by any Jiffy Lube service center where a trained technician can help.
The myth is that all synthetic oil is purely man-made and not based on oils found in nature. In today’s synthetic oils, crude or natural oil is purified and then structurally modified to produce improved performance.
Today’s motor oils contain base oils and several additives that are carefully blended together. Synthetic base oils may be made from a variety of chemicals and processes that are designed to have excellent performance at extreme temperatures and operating conditions. Select additives are used to improve flow characteristics and lubricating quality in the harshest of conditions. Conventional base oils are refined from crude oil. Additives may also be carefully added to conventional base oils to make quality motor oils as well.
While synthetic motor oils can provide exceptional performance and protection, they don’t eliminate the need for regular oil changes. High quality synthetic motor oils can perform and protect better than conventional motor oils, but engines running on gasoline or diesel will continue to naturally contaminate and stress the oil, and the additives can only work for so long.
Let’s take SAE 10W-30 as our example …
The numbers come from a standardized industry scale from the SAE (Society of Automotive Engineers) to describe how well an oil flows (viscosity) through an engine when the engine is cold in the morning and when the engine is warmed up and working hard. But the one thing to remember is to match this number to what is recommended in your vehicle owner’s manual.
Most motor oils today have two numbers (multi-viscosity): for example, SAE 10W-30. The low number with the “W” (stands for Winter), or cold temperature number, relates to how well the oil can be pumped or pushed through the engine at certain cold temperatures.
The second number (in this example “30”) relates to how well the oil flows at higher engine temperatures. When your engine heats-up the motor oil gets thinner. Problems can arise when the motor oil gets too thin and can no longer keep some of the moving parts separated by the oil. So your oil is always maintaining a delicate balance: it needs to flow well when the engine is cold but also maintain an oil film at higher temperatures to keep metal parts lubricated and separated. Be careful – higher or lower viscosity numbers may not be compatible with your engine. To find out what oil grade is right for your engine, check your vehicle owner's manual.
Jiffy Lube takes pride in educating customers about the role of motor oil, as well as the timing of your next oil change and the choices that you will have to make when you get there. Stop by your local Jiffy Lube to find out why the Jiffy Lube Signature Service® Oil Change is miles ahead of a traditional oil change.
