![]() To find out what oil grade is right for your engine, check your vehicle owner's manual. Be careful, as higher or lower viscosity numbers may not be compatible with your engine. 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. Problems can arise when the motor oil gets too thin and can no longer keep some of the moving parts separated by the oil. The cost of an oil change can range from 20 to 100 at a lube shop (and around 30 to 45 if you do it yourself). When your engine heats up, the motor oil gets thinner. The second number (in this example 30) relates to how well the oil flows at higher engine temperatures. 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. Most motor oils today have two numbers (multi-viscosity): for example, SAE 10W-30. But the one thing to remember is to match this number to what is recommended in your vehicle owner’s manual. 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. Regular oil changes will remove suspended contaminants before sludge can form, helping keep your engine running cleaner, smoother and more efficiently. When the oil becomes saturated with contaminants and cannot hold any more in suspension, the excess falls out of suspension and can form deposits in the engine, one of which is known as sludge. ![]() These same attributes apply to your motor oil. When a sponge becomes over saturated, it can no longer hold any more fluid. We all know that a sponge has the ability to pick up and hold fluids, dirt, etc. Think of motor oil like you would think of a sponge. It is important to check your motor oil level frequently to make sure that this doesn’t occur.ĭid 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. When your motor oil level is low, it will cause the engine temperature to rise. As the oil circulates, it carries away some of the heat generated as a result of the combustion process. Another important function of oil is cooling. WHAT WE DO: Jiffy Lube ® drains and replaces it with transfer case fluid that meets or exceeds your manufacturer’s specifications. ![]() One of the main functions of oil is to keep these moving parts separated from each other, preventing damage, friction and wear. Like an oil change for your 4X4’s transfer case, help optimize performance and longevity of this key component with a visit to Jiffy Lube ® for a transfer case fluid exchange. Did you know that some of the moving parts within your engine never really touch? It’s true! They ride on a thin layer of oil. ![]()
