NMF Ionic Friction Reducer, 4 Engines (16 oz) APPLICATION: engine, transmission, differentials, hydraulics, power steering, fuel, greased joints/bearings. Leaves no residue. Safe for automatic transmissions and wet clutches; will not cause slippage. TECHNOLOGY: NMF eliminates the attractive electrical relationship which is the root cause of most friction. Creates a negative-negative operating environment so metal parts repel each other and residue is repelled away from metal. RESULTS: less wear and clean parts. All-American product by a veteran-owned business. Purchase comes with the following GUARANTEES: (1) NMF reduces wear and heat to your satisfaction or money back (2) if used in an engine, NMF cleans the engine to your satisfaction or money back (3) if used in fuel, NMF cleans the fuel injectors to your satisfaction or money back (4) for a fully-treated semi truck only, NMF improves fuel efficiency or money back and (5) on ASTM D4172 reduces wear by at least 10% or money back. WEAR TEST PROVEN: ASTM D4172 is the standard measurement of friction trusted by SAE engineers. Petro Lubricant Labs of Lafayette New Jersey conducted ASTM D4172 on Shell Rotella T 15W40 without and with NMF. NMF improved the wear-resistance of Rotella T by 22% and reduced the overall friction coefficient by 36%. ** New engines need friction for proper piston ring seating. Apply NMF after break-in period ** RACE TEST PROVEN: Motorsports teams at all levels, from IndyCar to the Bandit Big Rig Series, Monster Jam circuit, and dirt tracks and drag strips around the world use NMF to keep temperatures down and parts alive. Sponsored motorsports teams have no monetary or material incentive to promote NMF. We don't pay -- all we provide is NMF and t-shirts, hats, patches, etc. for the driver and crew chief.
