I certainly want to strain the oil through something that doesn't pass particles large enough to clog orifices or block sliding parts. Filling through a 15-25 micron nominal element is good enough to me.
I'd bet that the bulk oil isn't Dexos 1 gen 2 ... that concerns me.
I have my suspicions as well, Why put the latest and greatest, and take on the associated costs into many vehicles that may not need it. More than likely a run of the mill 5w-30, API SN put out by ExxonMobil. Attached is the photo of the tank. Looks like it has been in use for years.
