\nSignature Series Fights Wear<\/h4>\n 75% more engine protection against horsepower loss and wear.<\/p>\n
Sequence IVA Engine Test – Lower Number = Less Wear<\/h2>\n <\/p>\n
Based on independent testing of AMSOIL Signature Series 0W-20, in ASTM D6891 as required by the API SN specification.<\/p>\n
\nSignature Series Delivers Powerful Protection<\/h4>\n 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.<\/p>\n
<\/p>\n
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.<\/p>\n
\nSignature Series Protects Against LSPI<\/h4>\n AMSOIL Synthetic Motor Oils achieved 100% protection against LSPI.<\/p>\n
<\/p>\n
Example of piston damage due to an LSPI event observed during the testing of a competitor\u2019s motor oil. The red arrows indicate sections of the ring land that have broken away from the piston.<\/p>\n
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.<\/p>\n
\nSignature Series Resists Viscosity Increase<\/h4>\n 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.<\/p>\n
Sequence IIIH Engine Test – Lower number = better viscosity control<\/h2>\n <\/p>\n
