Wolf Oil launches engine oils that meet GM dexos1 Gen3 spec

Wolf Oil Corporation has launched three engine oils, including two that have been officially approved as meeting the latest General Motors dexos1TM Gen3 specification.

WOLF ECOTECH 0W20 SP/RC D1-3 and WOLF ECOTECH 5W30 SP/RC D1-3 are officially approved products. WOLF ECOTECH 5W20 SP/RC D1-3, while meeting the dexos1TM Gen3 specification, has not been approved as GM is not yet currently supporting the SAE 5W-20 viscosity grade. However, all three products are backward compatible with older dexos1 specifications and also meets ILSAC GF-6 A specifications. 

The new dexos1TM Gen3 specification is designed to meet performance needs of GM vehicles and includes a more recent version of the stochastic pre-ignition (SPI) test, fuel economy test, and upgraded performance limits for deposit and sludge tests. 

There is some overlap with dexos1 Gen 2 when compared to the latest industry standard, ILSAC GF-6, but dexos1 Gen 3 still has enhanced oxidation, turbocharger protection and engine cleanliness. 

GM has set a mandatory transition date of September 1, 2022 to meet its dexos1 Gen 3 specification. As a result, Wolf Oil, based in Antwerpen, Belgium, said it will be phasing out its GM dexos1TM Gen2 engine oils over the coming months.
