Anyone know what the SAE/API ratings are for dexos D, 0W-20?

Only two approved oils, ACDelco and Mobil (same oil as XOM is the supplier for ACDelco) but nothing on websites gives any information.

dexos1 -- Gasoline engines only dexos2 -- Most diesel engines, and a few gasoline engines (Corvette here; gasoline in Euro). Gasoline here is now low sulfur, so why not? As long as LSPI is not a concern. dexosD -- 0w20 diesel only, very special purpose right now. I expect it will expand to gasoline and diesel engines later.

I'm just surprised that dexosD isn't FA-4, maybe to eliminate confusion with HD diesel oils (which seem to be -30 weights).

bullwinkle, FA-4 has HTHS 2.9-3.2, and dexosD is around 2.6. I guess FA-4 can't go low enough. Other differences, FA-4 is higher SAPS than dexosD. Noticing Mobil Delvac 1â„¢ Advanced Fuel Economy (HTHS 3.2) does have a gasoline rating, SN at least. It could be used in a lot of passenger car gasoline engines.
