Wrenches are essential tools for changing motor oil, with different sizes available such as SAE and metric. Oil filter removal also requires the correct sized socket or combination wrench. Specialty tools like the Ibetter oil filter removal tool and the WORKPRO universal wrench are designed for specific oil filters. It is recommended to use cap type, three-leg, chain, or band wrenches to loosen the oil filter. Novice individuals may struggle with oil changes without proper tools or experience. A combination wrench and chain-type oil-filter wrench are commonly used in oil changes.
