    Which one?

    Pretty straightforward- the minus is that you spend a little money.

    The plus: Break-in lubricants are removed and replaced with fresh, removing with them (and the oil filter) most of the metal that wears away from surfaces as the engine is broken in.

    This is not a "Required" service. It IS recommended, primarily as an investment in your engine's longevity.

    trust me , 20 Hour can add many hours to the life. AS stated by Don.
