Routinely changing your oil ensures that your engine stays well-lubricated and healthy, but it's a slightly more involved process than you might expect. If you haven't gotten your hands dirty by changing your oil in the past, then you may be surprised by the work that goes into this simple job. Check out these three ways that changing your oil does more than just refresh your motor's lubricant.

1. New Oil Filter

In the distant past, mechanics would sometimes perform oil changes without replacing the oil filter at the same time. This procedure made sense since most manufacturers recommended frequent oil changes, and the filter may still have had some life left. With every manufacturer now recommending at least 3,000-mile oil change intervals, you should now have your filter changed with every oil service.

Replacing your filter is more than just a chore that you need to do, however. Your filter catches any small contaminants in your oil, a process that both protects your internal engine parts and extends the life of your oil. It may not be the first thing to come to mind when you think about changing your oil, but that new filter is a critical part of this routine job.

2. Replacement O-Rings, Gaskets, and Washers

Oil leaks can cause minor headaches or be significant sources of trouble, depending on their severity. When you change your oil, you're exposing several locations where oil leaks may occur, including the drain plug and oil filter. O-rings, gaskets, and washers help to ensure that your engine oil stays where it belongs: inside of your engine.

Unfortunately, these simple items can wear out over time, and most are single-use components. When your technician changes your oil, they will replace the gasket and crush washer on your drain pain bolt and ensure that your oil filter has a new O-ring. These simple service items guarantee that an oil change doesn't quickly lead to an oil leak.

3. Leak And Fluid Inspection

Most shops will also perform a quick inspection of essential items when they replace your oil and filter. This inspection usually includes checking your bulbs and fluid levels, as well as looking for any signs of leaks. Since the technician must get underneath your car to drain the oil, this is the perfect time to look for dripping fluids or other evident signs of trouble.

Getting new oil into your car is one of the most critical services you can perform to ensure its longevity, but there's much more at work during a simple oil change. By regularly completing this maintenance task, you can keep your oil fresh while avoiding potentially troublesome future complications.
