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, AMSOIL Signature Series now provides motorists a new level of engine protection that raises the bar for motor oil performance in increasingly demanding modern engines.
AMSOIL Signature Series 100% Synthetic Motor Oil features an industry-leading formulation with premium base oils and a precision-engineered additive system. It helps control wear and maintains viscosity even in extreme heat, pressure and cold-start operating conditions. It delivers 2X better protection against volatility,1 helping reduce oil consumption, minimize top-offs and keep engines cleaner over time.
“This next generation of AMSOIL Signature Series represents nearly a decade of precision engineering and rigorous testing,” said AMSOIL Director, Product Marketing Automotive & Commercial Alex Thompson. “Developing a product that demonstrates meaningful performance improvements over an already industry-leading formulation was not easy, but necessary to continue protecting both modern and late-model engine platforms at the highest level.”
Low-speed pre-ignition (LSPI) can damage pistons and other critical engine components, and remains a concern in today’s turbocharged, direct-injection engines. AMSOIL Signature Series 100% Synthetic Motor Oil delivers 4X more piston protection against LSPI2 while maintaining a strong, stable formulation that continuously delivers outstanding performance. In Sequence IIH testing, AMSOIL Signature Series provided 72% more protection against piston deposits than required by industry standards.3
Additional benefits include protection against sludge, thermal stability for easier cold starting and limited oil consumption. AMSOIL Signature Series Synthetic Motor Oil is available in eight viscosities: 0W-16, 0W-20, 5W-20, 0W-30, 5W-30, 10W-30, 0W-40 & 5W-50. It provides guaranteed protection in normal service for extended drain intervals up to 25,000 miles or one year, whichever comes first. New Signature Series is rolling out as inventory of the prior formulation is used up.
