Synthetic Motor Oil 5W-30 API Certified (OEF)
Advanced Engine Protection and Performance
OE Synthetic motor oil for mechanics and vehicle owners seeking the peace of mind protection and exceptional value of synthetic motor oil. It delivers 100% synthetic engine protection for advanced automotive technology, including turbochargers and direct injection fuel systems. OE is specially formulated for extended oil drain intervals recommended by original equipment manufacturers (OEM).
Delivers Enhanced Anti-Wear Protection
OE Synthetic motor oil provides excellent wear control and protects critical engine components such as pistons and camshafts. This additional protection is especially important in severe environments, as today's smaller displacement engines typically run lower viscosity oils. Camshaft wear can lead to poor valve adjustment, significantly reducing engine performance and resulting in expensive repairs. The wear test on Peugeot TU3M (CEC L-38-A-94), which must be passed to meet GM dexos1 Gen 2 specification, determines the wear-limiting capability of motor oil. Over 100 hours, a four-cylinder test engine must endure severe, wear-inducing conditions. AMSOIL OE motor oil delivers wear protection 47% higher than the requirements of GM dexos1 Gen 2 specification.
Protects Pistons Against Low-Speed Pre-Ignition
OE Synthetic motor oil features unique chemistry proven to protect your engine against the damaging effects of low-speed pre-ignition (LSPI). LSPI is spontaneous ignition of the fuel/air mixture before ignition by the spark plug. Most new engines feature gasoline direct injection (GDI), typically paired with a turbocharger. These technologies increase the likelihood of LSPI events, which can destroy pistons and connecting rods. Properly formulated motor oil is critical to protect your engine against LSPI.
Original equipment manufacturers (OEMs) such as GM have addressed this issue by designing tests to determine the LSPI prevention capability of motor oils. OE Synthetic motor oil achieves 100% protection against LSPI in engine testing required by GM dexos1 Gen 2 specification—no occurrences were recorded throughout five consecutive test runs.
