OE Synthetic Motor Oil (OES, OEZ, OEM, OEF, OET)
• Protects against wear
• Achieved 100 percent protection against LSPI1
• Fights sludge and deposits
• API-licensed to meet the requirements commonly found in owner’s manuals
Advanced Wear Protection OE Synthetic Motor Oil provides excellent wear control and protects vital engine parts like pistons and cams. This added protection is particularly important given the extreme environments produced by many of today’s smaller displacement engines that typically run lower-viscosity motor oil. Camshaft wear can alter valve timing, greatly reducing engine efficiency.
The Peugeot* TU3M Wear Test, which must be passed to meet the GM* dexos1® Gen 2 specification, determines a motor oil’s ability to limit wear. For 100 hours the four-cylinder test engine is subjected to extreme, wear-inducing conditions. AMSOIL OE Motor Oil provided 47 percent more wear protection than required by the GM dexos1 Gen 2 specification.2
Protects Pistons from Low-Speed Pre-Ignition Like AMSOIL Signature Series and XL, AMSOIL OE features an advanced detergent system for advanced protection. Most new engines feature gasoline direct injection (GDI), often combined with a turbocharger to boost power and improve fuel economy. These new technologies pose significant challenges to motor oil, one of which is low-speed pre-ignition (LSPI). LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. It occurs in today’s advanced engines and is much more destructive than typical pre-ignition. OEMs like GM have addressed the issue by designing tests to determine a motor oil’s ability to prevent LSPI. OE Synthetic Motor Oil provided 100 percent protection against LSPI1– zero occurrences were recorded in five consecutive tests.
LSPI is another version of engine knock, which has been around since engines were invented. In this case, it occurs under low-speed, high-torque conditions in turbocharged gasoline direct-injected engines and is more destructive than typical engine knock.
OE Synthetic Motor Oil provides excellent wear protection for today’s advanced automotive technology, including turbochargers and direct injection. It’s specifically formulated for the longer drain intervals recommended by original equipment manufacturers (OEMs).
- Outperforms conventional motor oil
- Protection to cover longer oil life monitor drain intervals
