Why This Method is Recommended

Performing your own oil change is not only a cost-effective choice but also incredibly empowering. When you change your own oil, you have full control over the quality of the oil and filter used. You can choose brands you trust, ensuring your engine gets the best possible protection. This method also helps you become more familiar with your car’s undercarriage, allowing you to spot other potential issues early. While professional services are convenient, doing it yourself ensures the job is done right, to your standards, and often faster than waiting at a shop. It’s a key part of responsible car ownership, much like learning how to change a tyre.

Detailed Step-by-Step Guide

Step 1: 1. Prepare Your Vehicle and Gather Supplies

First, make sure you have all your tools and supplies ready. This prevents interruptions once you start. Refer to your car’s owner manual to find out the exact type and amount of engine oil your car needs. It will also specify the correct oil filter. Drive your car for about 5-10 minutes to warm up the engine. Warm oil flows more easily, making the draining process quicker and more complete. Once slightly warm, park your car on a level surface. Engage the parking brake. Place wheel chocks behind the rear wheels for extra safety. Now, carefully use your jack to lift the front of your car, then place the jack stands under the vehicle’s frame. Never rely solely on the jack. Ensure the car is stable on the jack stands before proceeding. Safety is paramount when working under a car.

Step 2: 2. Drain the Old Engine Oil

Crawl under your car, taking all safety precautions. Locate the oil drain plug. It’s usually a large bolt at the lowest point of the oil pan, which is a metal reservoir at the bottom of the engine. Position your drain pan directly underneath the plug. Using your ratchet and the correct size socket, carefully loosen the drain plug. Be prepared, as oil will start to trickle out once it’s loose. Once you can turn it by hand, remove the plug completely. The hot oil will gush out quickly, so make sure your hands are clear. Let the oil drain completely. This can take anywhere from 10 to 20 minutes, depending on the car and oil temperature. While it drains, inspect the drain plug for any damage to its threads or washer. You might need to replace the washer if it looks compressed or damaged.

Step 3: 3. Remove the Old Oil Filter

While the oil finishes draining, locate the oil filter. It’s typically a cylinder-shaped component, often near the engine block. Place your drain pan directly below the filter, as more oil will come out. Use your oil filter wrench to loosen the old filter. Once it’s loose enough, you can usually unscrew it by hand. Be careful, as the filter will be full of old oil and can be hot. Let the remaining oil drain into the pan. Once all the oil has drained from the filter housing, dispose of the old filter responsibly. Many auto parts stores accept used oil and filters for recycling.

Step 4: 4. Install the New Oil Filter and Replace Drain Plug

Take your new oil filter. Dip your finger in some new, clean engine oil and lightly lubricate the rubber gasket around the rim of the new filter. This ensures a good seal and makes it easier to remove next time. Screw the new filter onto its housing by hand until it’s snug. Then, use your oil filter wrench to give it about another quarter to half-turn. Do not overtighten it, as this can damage the filter or its housing. Next, clean the area around the oil pan drain plug opening with a rag. Reinsert the drain plug, ensuring it’s tightened securely with your ratchet. Again, do not overtighten, but make sure it’s snug enough to prevent leaks. Once the drain plug and new filter are in place, you can carefully remove the jack stands and lower your car back to the ground.

Step 5: 5. Add New Engine Oil

Open your car’s hood and locate the oil filler cap, usually marked with an oil can symbol. Remove the cap. Place your funnel into the oil filler neck. Slowly pour the new engine oil into the funnel. Refer to your owner’s manual for the exact capacity. It’s often best to pour about 80-90% of the recommended amount, then pause. Wait a few minutes for the oil to settle in the engine. Remove the funnel and replace the oil filler cap securely. Double-check that all caps are on and everything is tightened.

Step 6: 6. Check Oil Level and Inspect for Leaks

With the new oil in, it’s time to check the level accurately. Start your engine and let it run for a minute or two. This circulates the new oil through the engine and filter. Turn off the engine and wait another 5-10 minutes for the oil to settle back into the oil pan. Now, pull out the dipstick, wipe it clean with a rag, reinsert it completely, and then pull it out again. Check the oil level. It should be between the ‘min’ and ‘max’ marks. If it’s low, add a small amount of oil, wait a few minutes, and recheck. If it’s too high, you might need to drain a small amount. Finally, look under the car for any signs of leaks around the drain plug or oil filter. If you see any, tighten them slightly. You can also take your car for a short drive, then recheck for leaks upon your return.

Troubleshooting Common Issues

The drain plug or oil filter is stuck and won’t loosen.

For a stuck drain plug, ensure you’re turning it counter-clockwise. A breaker bar can provide more leverage. For a stuck oil filter, try a different type of oil filter wrench, like a strap wrench, or a larger filter wrench. Sometimes, a quick tap with a rubber mallet on the wrench handle can help break it free. Always ensure your tools are correctly sized.

Oil is leaking after the change.

Carefully check both the drain plug and the oil filter. The drain plug might not be tight enough, or its washer might be damaged and need replacement. For the oil filter, ensure the old gasket was removed (sometimes it sticks to the engine) and that the new filter’s gasket was lightly lubricated and the filter is tightened properly, but not overtightened.

The new oil level is too high.

If you’ve overfilled, you’ll need to drain some oil out. Place your drain pan back under the car and carefully loosen the drain plug just enough for a small amount of oil to trickle out. Tighten the plug, wait a few minutes, and recheck the level. Repeat until the level is correct.

Common Mistakes to Avoid

Not using jack stands: Never work under a car supported only by a jack. Always use jack stands for safety.
Overtightening the drain plug or oil filter: This can strip threads or damage components, leading to leaks or difficulty removing them next time. Hand-tighten filters and then give a small turn with the wrench; drain plugs should be snug but not wrenched on with extreme force.
Forgetting to replace the old oil filter gasket: The old filter’s rubber gasket can sometimes stick to the engine block. If you install a new filter over the old gasket, you’ll have a double gasket, leading to a severe leak.
Using the wrong type of oil: Always check your owner’s manual for the exact viscosity and specification of oil required for your vehicle.
Not disposing of used oil properly: Used engine oil is a hazardous waste. Never pour it down a drain or on the ground. Take it to an auto parts store or local recycling center.

Pro Tips

Consider an oil change interval sticker: Many new oil filters come with a sticker you can place in your windshield to remind you of your next oil change mileage and date.
Check other fluids: While you’re under the hood, take a moment to check your power steering fluid, brake fluid, coolant, and windshield washer fluid levels.
Always have extra rags: Oil changes can be messy. Having plenty of rags on hand will make cleanup much easier.
Invest in a fluid extractor: If you’re not keen on crawling under your car, a top-side fluid extractor can suck the oil out through the dipstick tube, eliminating the need for a drain plug removal on some vehicles (check compatibility).

Final Result

After completing these steps, your car will have fresh, clean engine oil, ensuring its engine runs smoothly and efficiently. You’ll have the satisfaction of knowing you performed a crucial maintenance task yourself, extending your vehicle’s life and saving money in the process. Your car should feel responsive and perform optimally.

Summary

Learning how to change oil is a valuable skill for any car owner. By following these detailed steps, you can confidently perform this essential maintenance task yourself. Remember to prioritize safety with jack stands and wheel chocks, use the correct oil and filter for your vehicle, and dispose of used oil responsibly. Regularly changing your oil is key to engine longevity and overall vehicle health, keeping your car running its best for years to come. Congratulations, you’ve just mastered a fundamental aspect of car care!
