Why Do It Yourself?
When the price of an oil change at a shop climbs toward $80, the idea of doing it yourself becomes very appealing. A recent comparison showed that a DIY job can cut the cost in half, saving roughly 50% of what you would pay for a professional service. Beyond the savings, the process gives you a clearer understanding of how your engine runs and lets you keep an eye on the quality of the oil you’re using. It also eliminates the need to schedule a service appointment, allowing you to fit the job into your own timetable. For many drivers, the confidence gained from performing the task themselves is worth the extra effort.
Tools and Supplies You’ll Need
Before you lift the car, gather the items that will make the job smoother. You’ll need a 15‑mm socket or a box wrench to remove the drain plug, a funnel that fits the oil filler opening, a new oil filter (the ultra‑synthetic type works well for most engines), and a drain pan with a built‑in drain plug to catch the old oil. A set of gloves protects your hands, and a rag or paper towels will help clean up any spills. If you’re using a 5‑quart or 6‑quart capacity, make sure the oil you buy matches the vehicle’s specifications—most cars call for 5W‑30 or 0W‑30 synthetic oil. Having a small bucket or container for the old oil can also be handy if the drain pan is not large enough.
Getting the Car Ready
Start by raising the front of the vehicle with a jack and securing it on jack stands. Open the hood and locate the oil filler cap; it usually reads the recommended oil type. If you’re unsure, check the owner’s manual for the exact viscosity. Place the drain pan under the oil drain plug, which is typically found on the underside of the engine block. Some engines have a small opening that looks like a drain; be sure you’re looking at the correct one. It can help to mark the drain plug’s position with a piece of tape so you can re‑install it in the same spot later.
Draining the Old Oil
With the car lifted, loosen the drain plug with the socket or wrench. Keep the plug in a clean spot so you can re‑install it later. Let the oil flow out slowly; hot oil drains more quickly and removes more sludge. Once the flow slows to a drip, replace the plug, tightening it just enough to stop leaks but not so tight that it damages the threads. Wipe the area around the plug to remove any oil residue, and check for metal shavings—if you see them, it may indicate a more serious issue. A clean drain pan will catch the oil, preventing spills on the driveway or garage floor.
Replacing the Filter and Refilling
Locate the oil filter, usually a cylindrical component on the side of the engine. Use a filter wrench or your hands to unscrew it counter‑clockwise. Before installing the new filter, apply a thin layer of fresh oil to the rubber seal; this ensures a good seal and prevents leaks. Screw the filter on clockwise until it’s snug, then give it a final half‑turn. Next, remove the oil filler cap and pour the new oil slowly through the funnel. Pouring slowly allows air to escape and prevents splashing. After adding the recommended amount—often between the middle two marks on the dipstick—re‑attach the cap and start the engine. Let it run for a few minutes, then check the dipstick again to confirm the oil level is correct.
Cleaning Up and Disposal
Once the oil level is correct, turn off the engine and let the car sit for a few minutes so the oil settles. Use a rag to wipe the dipstick and any oil that may have spilled. The old oil should be collected in the drain pan and transferred to a sealed container. Many auto parts stores accept used oil for free; simply bring the container to the store’s recycling bin. If you prefer, you can also contact a local recycling center that accepts automotive fluids. Proper disposal prevents environmental contamination and keeps your driveway clean. Don’t pour oil onto the ground or down the drain, as it can damage plumbing and harm wildlife.
Final Thoughts
Changing your oil at home is a practical way to save money and gain confidence in basic vehicle maintenance. By following the steps above—preparing the car, draining the old oil, replacing the filter, refilling, and disposing of the waste—you’ll keep your engine running smoothly and avoid the high costs of shop services. With a little preparation and the right tools, the next oil change can be a quick, satisfying DIY project that reinforces your understanding of how your car works.
