Lubenium® Engine Treatment is formulated with Nanum AFMS™ (Anti-Friction Metal Surface) advanced anti-friction technology to treat the metal surfaces of both gasoline and diesel fueled engines. As motor oil is pumped through the engine, Lubenium® Engine Treatment molecules interact with all of the metal surfaces, chemically bonding to create a protective layer that reduces damaging friction and heat. Temperature reduction is especially important in today's smaller import and compact engines, which tend to run hotter. Lubenium® Engine Treatment is particularly effective under extreme pressure conditions, in areas of the engine where severe metal-to-metal contact squeezes motor oil out and away. It adheres to metal surfaces in the engine, meaning Lubenium® works to protect your engine even before the motor oil is fully circulating.
