This new post break-in lube developed by world renowned engine master literally pours-in 4-7hp. A three step process for reducing friction and developing more power during the break-in process that lasts throughout the engine's lifespan. This process protects the engine so well from wear that the engine's lifespan is increased exponentially. This is bottle #3 only and is for an already broken in engine. For those who have a fresh engine not yet broken in, use the three part break-in lube here.
