To begin with, regular oil changes are vital for engine maintenance. Also, it's advised to change the oil filter with each oil change. You also need tools like a wrench, oil filter wrench, drain container, and funnel. Clean rags and newspapers are useful for spills. Before starting, locate the drain plug and oil filter, warm up the engine, and gather tools. Raise the vehicle, position the drain pan, and remove the drain plug. Replace the old filter with a new one, ensuring they match.
