First of all, regular oil changes are critical for preventive maintenance, detecting issues, and preventing engine wear. Some models have an oil life indicator system that extends the interval beyond 3000 miles but not exceeding 7500 miles. You can support the vehicle, place a drain pan under the plug, remove the plug, and inspect the old oil for metal particles. Remove the filter, clean the surface and gasket, compare old and new filters, lubricate the gasket, and install new filter. Lower the vehicle, check the valve stem core, and top it off with oil. Check for leaks, wait for the engine to cool down, and dispose of old oil properly.

Access to the oil drain plug and filter is improved by hoisting the vehicle, using ramps, or using jackstands for vehicle support.

After changing the oil, check for leaks, wait for the engine to cool down, and dispose of the old oil properly. Specific models, like 2.7L V6 versions, may have additional instructions, such as removing a canister-type filter housing, replacing O-rings, and tightening to specified torque.
