How to change engine oil?

Changing your car’s engine oil is an essential maintenance task that helps keep your engine running smoothly and prolongs its lifespan. Here’s a step-by-step guide to help you change the engine oil safely and effectively: 1. **Prepare your tools and materials:** You will need fresh engine oil (check your owner’s manual for the correct type and quantity), a new oil filter, an oil filter wrench, a wrench or socket set to remove the drain plug, an oil drain pan, a funnel, gloves, and rags or paper towels. 2. **Warm up the engine:** Run your car for about 5-10 minutes to warm the oil slightly. Warm oil drains more completely and carries away more impurities. Then, park your car on a level surface, turn off the engine, and engage the parking brake. 3. **Raise the vehicle safely (if necessary):** Depending on your car’s clearance, you may need to use ramps or jack stands to access the drain plug and oil filter. Never rely on a jack alone for support — always use jack stands. 4. **Drain the old oil:** Place the oil drain pan beneath the oil drain plug, which is located on the bottom of the engine’s oil pan. Use the correct wrench to carefully loosen and remove the drain plug. Allow all the oil to drain out completely (this may take several minutes). After draining, clean the drain plug and replace its crush washer if applicable, then reinstall and tighten the drain plug securely. 5. **Remove and replace the oil filter:** Locate the oil filter (refer to your manual if unsure). Use the oil filter wrench to loosen and remove the old filter, taking care as it will contain some oil. Before installing the new filter, apply a thin layer of fresh oil to the rubber gasket on the new filter to ensure a good seal. Screw on the new filter by hand until snug, then give it another ¾ turn (do not overtighten). 6. **Add fresh oil:** Open the hood and remove the engine oil filler cap. Using a funnel, pour the correct amount and type of fresh oil into the engine. Check your owner’s manual for specifications. Replace the oil filler cap securely. 7. **Check for leaks and oil level:** Start the engine and let it run for a minute, then turn it off and wait a few minutes. Check under the vehicle for leaks near the drain plug and oil filter. Use the dipstick to check the oil level, and add oil if necessary to reach the recommended level. 8. **Dispose of used oil properly:** Collect the used oil in a sealed container and take it to a recycling center or an auto shop that accepts used oil. Never pour oil down drains or onto the ground. By following these steps carefully, you can change your engine oil yourself, saving money and ensuring your car runs efficiently. If you’re unsure at any point, consult your vehicle’s manual or seek assistance from a professional mechanic.
