Product Description

Engineered for enthusiasts seeking maximum protection and performance. Precision-formulated with cutting-edge technology and a longstanding devotion to making the world’s best motor oil. The result: engine protection that blows the doors off the highest industry standards.

Fights Engine Wear: 75 percent more engine protection against horsepower loss and wear1 than required by the industry standard, extending the life of vital components like pistons and cams. Develops a strong fluid film that keeps metal surfaces separated. Robust anti-wear additives further reduce wear in metal-to-metal contact regions for maximum engine life.

Signature Series Improves Startup Protection: AMSOIL provides better cold cranking viscosity, helping improve wear protection for engine components at startup.

Signature Series Fights Wear: 75% more engine protection against horsepower loss and wear.

Signature Series Delivers Powerful Protection: AMSOIL delivers powerful protection. How good is it? An independent lab compared AMSOIL synthetic motor oil head-to-head against a leading competitor in a 100,000-mile test. AMSOIL provided far superior wear protection and kept bearings looking like new.

Signature Series Protects Against LSPI: All AMSOIL Synthetic Motor Oils achieved 100% protection against LSPI.

Signature Series Resists Viscosity Increase: Signature Series is barely challenged by the industry-standard testing, demonstrating only a 0.1% viscosity increase. Even when the test length is doubled, AMSOIL delivered twice the viscosity control required by the standard.

Signature Series Helps Keep Engines Cleaner: Fortified with a heavy treatment of detergent additives, delivering 28% more acid-neutralizing power than Mobil 1 and helping engines stay cleaner, longer. 50% more detergents to help keep oil passages clean and promote oil circulation. Controls heat and minimizes performance-robbing deposits. Superior thermal durability that resists breakdown and keeps pistons clean. Provides 90% better protection against sludge.

Signature Series Guards Turbos: Protects turbochargers 72% better than required by the GM dexos1 Gen 2 specification.

Keeps Pistons Cleaner: Even after doubling the length of the industry-standard test, AMSOIL delivered 40% cleaner pistons than required by the standard.

Brand Information

AMSOIL specializes in developing synthetic lubricants that offer innovative answers to the greatest challenges vehicles and equipment present. The extraordinary performance of AMSOIL synthetic lubricants in a range of markets – automotive, powersports, industrial, racing and more – has made our influence in the industry unmistakable and our brand highly respected. Our commitment to innovation has resulted in legions of brand-loyal customers.

AMSOIL founder and industry pioneer Al Amatuzio built his company on the same principles that defined his career as a jet fighter squadron commander – excellence, integrity and strong leadership. In 1972, the breakthrough came. AMSOIL 10W-40 Synthetic Motor Oil, the result of years of research and inspired by aerospace technology, became the first synthetic motor oil in the world to meet American Petroleum Institute service requirements. It outperformed conventional oils on all counts, signaling a new age in lubrication science. Today, virtually every other motor oil manufacturer has recognized the superiority of synthetic lubricants and followed the AMSOIL lead with introductions of synthetic motor oils of their own. Accept no substitutes – AMSOIL is The First in Synthetics®.

AMSOIL invests heavily in product research and validation to ensure we remain at the industry’s forefront. Our on-site chemical and mechanical test facilities contain the sophisticated instruments needed to develop cutting-edge synthetic technology. AMSOIL synthetic lubricants are validated in long-range studies with taxicabs, delivery fleets, police and emergency vehicles, over-the-road trucks, wind turbines and industrial machinery.

Further testing occurs at race tracks around the world. AMSOIL lubricants have helped racing teams operating off-road trucks, stock cars, high-powered boats, dirt bikes and snowmobiles capture countless checkered flags and championships. We believe that Racing is Research,™ and we use the data our racing efforts generate to tailor AMSOIL formulations for even greater levels of performance and protection.
