The purpose of engine oil is to lubricate, clean, and dissipate heat caused by friction as internal engine components move against each other during operation. While engine oil circulates throughout the engine, the friction modifiers and conditioners begin to break down. In addition, the oil may pick up tiny fragments of metal; a natural byproduct of metal components continuously moving against each other. As all of these processes occur over the course of many miles, the engine oil begins to lose its ability to clean and lubricate. For most modern cars this process of breaking down can take about 5,000 miles or possibly less if you do a lot of city driving as idling and city driving results in higher heat conditions and lower oil pressures resulting in less oil circulation. Every manufacturer has their own specific recommendations for intervals normally varying between 3,000 and 5,000 miles with some synthetic oils only needing a change every 10,000 miles!
Changing your oil on a regular basis is also a great time for your trusted mechanic to look over your vehicle for other basic routine maintenance items, as most of us don’t generally check our fluids, tire pressures, brakes, or steering and suspension items as often as we should. All of these items are checked as part of every routine maintenance service at Zaks Auto so you don’t have to! In summary changing your oil is the most cost effective way to make sure that engine stays running for many thousands of miles to come. So change your oil on time so you can enjoy your commutes, vacations, and road trips without interruption!
