Selecting the right engine oil grade involves: 1. Choosing based on driving habits; 2. Selecting according to mileage; 3. Picking the appropriate grade for your vehicle model. The steps for changing engine oil are: 1. Remove the oil filter; 2. Loosen the drain plug at the oil pan to drain the oil; 3. Reinstall the drain plug; 4. Tighten the screws, pour new oil into the engine, and reinstall the oil filter. Engine oil functions include: 1. Separating sliding parts to reduce wear; 2.

Circulating carbon deposits, sludge, and wear particles back to the oil tank, using oil flow to clean contaminants from engine components.
