When we last published a story on this subject just two months ago, July 24, the number of General Motors approved dexos1™ Gen 2 (a.k.a. dexos1:2015) oils listed was 168. There are now 465 approved dexos1™ Gen 2 oils.
dexos1™ (First Generation) licenses became obsolete as of September 1, 2017.
The second generation dexos1™ specification was issued in 2015 to provide better vehicle performance as well as low speed pre-ignition (LSPI) protection, particularly for small displacement turbo-charged engines.
The new dexos1 Gen 2 specification is a significantly strengthened, higher performance standard, offering improved fuel economy, turbocharger deposit control, aeration, stochastic pre-ignition (SPI) control, oil oxidation and piston deposit control.
