Same here. Oil still looks very clean at 5K miles oil changes.

5W40 Mobil Delvac in CJ-4 Grade. Allows same oil weight for summer and winter and towing 5th Wheel in all seasons

I fill to 14 litres only to leave a bit of room for diesel in oil growth.

I always ran Motorcraft 15w40 in the summer and M1 TDT 5w40 in the winter. I think that proper weight oil with the CJ-4 specification is all that matters, I have yet to hear of a "bad" oil to use.
