Web link. Saw the following on the GM Dexos website:
“Please note: GM dexos 2 is being discontinued in 2025 and replaced by GM dexos D and GM dexos R. Vehicles equipped with diesel engines that used GM dexos 2 engine oil will use GM dexos D licensed engine oils, while vehicles equipped with gasoline engines will use GM dexos R licensed engine oils of the of the appropriate viscosity grade at their next oil change.”
I’m curious to see how Dexos D gets used in applications where an xW-30/xW-40 Dexos 2 was original spec. Maybe GM will allow the higher viscosities for D. That might be interesting to the 3.0 Duramax owners looking for a D approved oil but want more viscosity than 0W-20.
