After removing the oil filter, you should clean the mounting surface and compare the old and new filters.

When working under the vehicle, be cautious of the hot exhaust components to avoid burns or injuries.

Position a drain pan under the plug in the bottom of the engine and remove the plug using a proper size box end wrench or socket. Some models may have two drain plugs.

Performing regular oil changes is a critical aspect of preventive maintenance for home mechanics to ensure the engine's longevity. Adequate preparation with necessary tools and materials, such as rags or newspapers for potential spills, is essential. Access to the oil drain plug and filter can be improved by elevating the vehicle on a hoist, ramps, or jackstands, but caution is necessary due to hot exhaust components. Start the engine and allow it to reach normal operating temperature before parking on a level surface and shutting it off. Raise and secure the vehicle, and place a drain pan beneath the engine's plug. Remove the plug with a suitable wrench, wearing a rubber glove to avoid hot oil contact. After draining, inspect the oil for metal particles and clean the drain plug. Replace it securely, move the drain pan under the oil filter, and loosen the filter using a filter wrench. If necessary, puncture the filter to remove it. Wipe the mounting surface and check for remaining gasket material. Lubricate the new filter's gasket with engine oil and install it, tightening by hand. Lower the vehicle, add fresh oil, start the engine, and check for leaks. Recheck the oil level and monitor for leaks during the initial trips after the oil change. Proper disposal of the old oil is essential. Some late-model vehicles allow oil change intervals to be adjusted through the instrument panel's display function, typically set to 7,500 miles but can be changed if needed.

Before starting, ensure you have the necessary tools and plenty of rags or newspapers for oil spills.

After adding new oil, you should check the oil level on the dipstick, start the engine, check for leaks, and recheck the oil level.

Frequent oil changes are important preventive maintenance procedures that can prevent premature engine wear. As engine oil ages, it becomes diluted and contaminated, which can lead to engine damage.
