Vehicles equipped with an oil life indicator system illuminate a light or message on the instrument panel to signal the need for an oil change, typically allowing for extended intervals compared to the traditional 3000-mile mark, but it's recommended not to exceed 10,000 miles between changes. Frequent oil changes are crucial for preventive maintenance as aging engine oil becomes diluted and contaminated, contributing to premature engine wear. Before initiating the oil change, ensure you have the necessary tools and ample rags or newspapers for oil spills. Access to the oil drain plug and filter is improved when the vehicle is raised on a hoist, driven onto ramps, or supported by jackstands. Start the engine and let it reach normal operating temperature, facilitating easier oil drainage. Park on a level surface, shut off the engine, and remove the oil filler cap. Raise the vehicle, supporting it securely with jackstands. Carefully position a drain pan beneath the engine's drain plug, remove the plug with a proper-sized wrench, and be cautious of hot exhaust components. After draining, inspect the old oil for metal particles, clean the drain plug, and the surrounding area, then reinstall and tighten it. Move the drain pan under the oil filter, unscrew the filter cap, and remove both the cap and element. Clean the housing and cap thoroughly. Install a new O-ring seal and a new filter element into the cap, then insert them into the filter housing, securely tightening the cap. Lower the vehicle, add fresh oil through the filler cap using a funnel, and check the oil level with the dipstick. Start the engine for a minute, inspect for oil leaks, and recheck the dipstick. During initial trips after the oil change, monitor for leaks and proper oil levels. Properly dispose of the old oil by checking with local facilities or recycling centers. Lastly, reset the "Change Engine Oil" light using either of the two specified methods, depending on your vehicle's features, ensuring the Oil Life Monitor is successfully reset.

After replacing the oil filter and draining the oil, all tools should be removed, and the vehicle should be lowered. Then, the proper amount of fresh oil should be added to the engine, the oil level should be checked, and the engine should be inspected for any oil leaks.

The purpose is to signal the need for an oil change, typically allowing for extended intervals compared to the traditional 3000-mile mark.

These vehicles are equipped with an oil life indicator system that illuminates a light on the instrument panel when the system deems it necessary to change the oil. While this system may allow for longer intervals between oil changes than the traditional 3000-mile recommendation, it is advised not to exceed 10,000 miles before an oil change, regardless of the indicator. Frequent oil changes are crucial preventive maintenance procedures as engine oil ages and becomes diluted and contaminated over time, leading to premature engine wear. It's recommended to change the oil filter with every oil change for minimal cost and ease of installation. Before beginning the oil change, gather necessary tools and materials and ensure the engine is warm for efficient oil drainage. The vehicle should be safely supported, and a drain pan positioned under the oil pan's drain plug. Remove the drain plug carefully, allowing the oil to drain completely. After draining, clean the drain plug and surrounding area before reinstalling it securely. For V6 models, the oil filter should also be removed and replaced using an oil filter wrench. For four-cylinder models, the canister-type oil filter can be accessed from the top of the engine. Once the filter is replaced, remove all tools and lower the vehicle. Add the proper amount of fresh oil to the engine, check the oil level, and inspect for leaks. Dispose of the old oil properly, and if the vehicle has an Oil Life Monitor system, reset it following specific instructions. Regular oil changes and maintenance are essential for engine longevity and performance.
