The Bar for Motor Oil Performance Has Been Raised. Just Not to Our Standards.

GM* Dexos1™ Gen 3 is the next-generation motor oil specification designed to address the challenges today’s smaller, higher-powered engines present.

Dexos1 Gen 3 highlights

• Updated performance standard for deposit and sludge control

• Revised stochastic pre-ignition (SPI) test

• Improved fuel economy

• Backward compatible with previous GM specifications

GM set a mandatory transition date of Sept. 1, 2022 to meet the new specification. AMSOIL Signature Series, XL and OE Synthetic Motor Oils already outperform it.
