Concentrated Engine Break-In Additive

Lunati® Break-In Additive replaces the essential anti-wear molecules that have been removed from modern motor oils. It restores critical Zinc (ZDDP), Phosphorus and Sulfur to the proper levels needed for protection of internal engine parts – especially those in flat tappet valve trains. Designed for both conventional & full synthetic oils, this concentrated additive was developed to meet the needs of initial engine break-in as well as extended use with every oil change.
