Home mechanics should add fresh oil through the valve cover's oil filler cap using a funnel, pouring three quarts and allowing it to drain into the pan before checking the oil level with the dipstick.

Frequent oil changes are essential for preventive maintenance to prevent premature engine wear. Before starting the procedure, ensure you have all the necessary tools and rags or newspapers for spills. Access to the underside of the vehicle is improved by lifting it on a hoist, ramps, or jack stands. Familiarize yourself with the location of the oil drain plug before getting under the vehicle. Park the vehicle on a level spot and let the engine reach its normal operating temperature. Raise the vehicle and place a drain pan under the drain plug. Carefully remove the plug, allowing the old oil to drain into the pan. Inspect the oil for metal shavings and chips. Wipe off the drain plug and clean the area around the opening before reinstalling and tightening the plug. Move the drain pan under the oil filter and loosen the filter with an oil filter wrench. Unscrew the filter by hand, ensuring the open end is tilted up to prevent oil spillage. Wipe off the mounting surface on the block and remove any old gasket residue. Compare the old filter with the new one and lubricate the gasket of the new filter with engine oil before screwing it into place. Add fresh oil to the engine through the oil filler cap and check the level on the dipstick. Start the engine and check for leaks. Wait for the oil to drain into the pan and recheck the level on the dipstick. Dispose of the old oil properly. Reset the engine oil replacement reminder light.

Old oil should be disposed of properly by contacting a local disposal facility or environmental agency. It should never be poured into drains or onto the ground to prevent environmental contamination.

After an oil change, check for leaks and proper oil level during the first few trips to ensure everything is functioning correctly. The old oil should be disposed of at an oil reclamation center or an appropriate disposal site.

After draining the old oil and inspecting the drain plug for metal shavings and chips, you should wipe the plug clean, reinstall it, and securely tighten it.
