AMSOIL has launched a new formulation of its top-tier Signature Series Synthetic Motor Oil. Built upon a solid foundation of unsurpassed performance and protection, the AMSOIL Signature Series line now offers motorists a new level of engine protection that exceeds new and upcoming engine oil specifications.

AMSOIL Signature Series Synthetic Motor Oil provides 75 percent more engine protection against horsepower loss and wear than required by a leading industry standard1, extending the life of vital components like pistons and cams. Its strong fluid film keeps metal surfaces separated while its robust anti-wear additives further reduce wear in metal-to-metal contact regions for maximum engine life. It features an advanced detergent system to protect vital engine parts including pistons and rings.

Low-speed pre-ignition (LSPI) is a common issue found in today’s advanced engines and is much more destructive than typical pre-ignition. AMSOIL Signature Series achieved 100 percent protection against LSPI in the engine test required by GM’s dexos1® Gen 2 specification2. It is ideal for use in both turbos and direct injection engines, protecting turbochargers 72 percent better than required by the GM dexos1 Gen 2 specification3.

Additional benefits include sludge protection, thermal stability for easier cold starting and limited oil consumption. AMSOIL Signature Series Synthetic Motor Oil is available in seven viscosities: 0W-20, 0W-40, 5W-20, 0W-30, 5W-30, 10W-30 & 5W-50. It offers guaranteed protection in normal service for extended drain intervals up to 25,000 miles or one year, whichever comes first.

AMSOIL has been the recognized leader in synthetic lubrication since 1972.
