Signature Series 5W-30 Synthetic Motor Oil

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 wearthan required by the industry standard, extending the life of vital components like pistons and cams.
• Develops astrong fluid filmthat keeps metal surfaces separated.
• Robust anti-wear additives furtherreduce wearin metal-to-metal contact regions formaximum engine life.

Signature Series Fights Wear

75% more engine protection against horsepower loss and wear.A

A Based on independent testing of AMSOIL Signature Series 0W-20, in ASTM D6891 as required by the API SN specification.

Signature Series Fights Viscosity Breakdown

AMSOIL fights viscosity breakdown better than the competition,Oproviding superior protection of pistons, cams and bearings.

O Based upon independent testing of Mobil 1 Annual Protection Full Synthetic 5W-30, Schaeffer’s Supreme 9000 5W-30, Lucas Synthetic 5W-30, Valvoline Conventional Daily Protection 5W-30, Pennzoil 5W-30 and AMSOIL Signature Series 5W-30 in the Kurt Orbahn test. Oils purchased on 05/03/18.

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.PAMSOIL provided far superior wear protection and kept bearings looking like new.

P Testing conducted in an independent lab using AMSOIL Signature Series 5W-30 Synthetic Motor Oil and a leading synthetic-blend 5W-30 motor oil in Ford F-150 trucks with 3.5L twin-turbo engines.

Signature Series Protects Against LSPI

AMSOIL Synthetic Motor Oils achieved 100% protection against LSPI.B

Example of piston damage due to an LSPI event observed during the testing of a competitor’s motor oil. The red arrows indicate sections of the ring land that have broken away from the piston.

B Based on zero LSPI events in five consecutive tests of AMSOIL Signature Series, XL and OE 5W-30 Motor Oil in the LSPI engine test required by the GM dexos1 Gen 2 specification.

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.GG

GG Based on independent testing of AMSOIL Signature Series 5W-30 in the Sequence IIIH Engine Test (ASTM D8111), required by the ILSAC GF-6 and API SP specifications.

Signature Series Guards Turbos

Protects turbochargers 72% better than requiredCby the GM dexos1* Gen 2 specification.

C Based on independent testing of AMSOIL Signature Series 5W-30 in the GM turbo coking test.

Signature Series Cleans

Signature Series has 50% more detergentsDto help keep oil passages clean and promote oil circulation. It provides 90% better protection against sludge.DD

The oil pick-up tube screen is virtually free of sludge.

D vs. AMSOIL OE Motor Oil

DD Based on independent testing of AMSOIL Signature Series 5W-30 in the ASTM D6593 engine test for oil screen plugging as required by the API SN specification.

Signature Series Neutralizes Acids

AMSOIL Signature Series is fortified with a heavy treatment of detergent additive and it delivers 30% more acid neutralizing powerEthan Mobil 1,* and 36% more than Royal Purple,* helping engines to stay cleaner, longer.
