Frequent oil changes are important preventive maintenance procedures that can be done by the home mechanic. As engine oil ages, it becomes diluted and contaminated, leading to premature engine wear. It is recommended to install a new oil filter every time the oil is changed, as the minimal cost and ease of installation make it worthwhile. Before beginning the procedure, gather all necessary tools and materials. Have clean rags and newspapers on hand to mop up spills. Access to the underside of the vehicle is improved by lifting it on a hoist, driving it onto ramps, or supporting it with jack stands. Familiarize yourself with the locations of the oil drain plug and oil filter under the vehicle. Warm the engine to normal operating temperature and gather all necessary tools and oil. With the warm engine oil, raise and support the vehicle safely. Position a drain pan under the drain plug and use a wrench to remove it. Allow the old oil to drain completely and wipe off the drain plug. Clean the area around the drain plug opening and reinstall the plug securely. Move the drain pan under the oil filter and use a filter wrench to loosen and remove the old filter. Compare the old filter with the new one to ensure they are the same type. Clean the area where the oil filter mounts and apply a light coat of clean oil to the rubber gasket on the new filter. Attach the new filter following the tightening directions. Remove all tools and lower the vehicle. In the engine compartment, locate the oil filler cap and pour four quarts of fresh oil into the engine. Wait for the oil to drain and check the level on the dipstick. Start the engine and check for leaks at the drain plug and oil filter. Recheck the oil level and add more if necessary. During the first few trips after an oil change, check for leaks and proper oil level. Dispose of the old oil properly by taking it to a recycling facility. Do not pour it on the ground or down a drain.

Frequent oil changes are essential for preventive maintenance to prevent premature engine wear due to aging, diluted, and contaminated oil. Ensure you have all necessary tools and ample rags or newspapers to handle potential spills. To access the underside of the vehicle, it's beneficial to lift it on a hoist, drive onto ramps, or support it with jack stands. Familiarize yourself with the oil drain plug's location if it's your first oil change, anticipating potential issues before the engine and components become hot. Park on level ground, start the engine, and let it reach normal operating temperature, then turn off the engine and remove the filler cap. Raise the vehicle and support it on jack stands, remove the under-vehicle splash shield, and position a drain pan under the oil pan's drain plug. Remove the plug, allowing the old oil to drain into the pan and inspect it for metal shavings and chips. After draining, wipe the plug clean and the surrounding area, reinstall and securely tighten the plug. Position the drain pan under the oil filter, loosen the filter using a filter wrench, wipe the mounting surface, ensure there's no residue, and compare the old filter to the new one. Lubricate the new filter's gasket with engine oil and hand-tighten it following directions on the canister or packing box. Remove tools and lower the vehicle, add new oil through the filler cap, pour three quarts, wait, check the level with the dipstick, start the engine, and check for leaks. Afterward, wait, recheck the dipstick level, and add oil if necessary. Monitor for leaks and proper oil levels during the first few trips after the oil change. Dispose of the old oil properly, as it cannot be reused, and consult local authorities or recycling facilities for disposal instructions, never pouring it into drains or onto the ground.
