Prolong Engine Treatment

Prolong Engine Treatment is formulated with Prolong’s AFMT™ advanced technology to treat the metal surfaces of both gasoline and diesel fueled engines. As motor oil is pumped through the engine, Prolong 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 that tend to run hotter. Prolong Engine Treatment is particularly effective under extreme pressure conditions, in the very areas of your engine where severe metal-to-metal contact squeezes motor oil out and away. Prolong Engine Treatment adheres to metal surfaces in the engine, which means Prolong is working to protect your engine even when the motor oil is not yet fully circulating.

Unlike other engine treatments on the market, Prolong Engine Treatment does not contain any solid particles such as PTFE resins, ‘molys’, zinc, copper or graphite. There is simply no other product that works as well as Prolong to reduce friction and heat in your vehicle’s engine.

How to Use

Prolong Engine Treatment is quick and easy to use, just pour it right into the engine crankcase. For first use in a 4 to 5 quart crankcase, pour in the full contents of a 12 oz. Prolong Engine Treatment bottle. You can do this as part of or in between oil changes. Then use the 8 oz. Prolong Engine Treatment Booster for follow-up applications when the motor oil is changed. The Booster size, with the same superior formula, renews Prolong protection to the maximum level. It is recommended that the Booster be used at each oil change, definitely within every six months or 6,000 miles. The vehicle manufacturer’s recommended service schedule should always be followed.

For other crankcase capacities or engine applications, use Prolong Engine Treatment at 10% of the volume of oil.
