Fully synthetic oil. As the name suggests, fully synthetic oils are purely synthetic with no mineral oil. Semi and fully synthetic oils have an additive blended into them called a friction modifier. This helps the oil defy gravity. When the engine is stopped the oil stays at the top, coating the surface of the vital engine components, and ensuring they don’t rattle on start-up in the morning.
