Nothing exotic. I've been a long time user of Blackstone Labs oil analysis services. Long story-short, unless you have a severe duty application like racing and a high-end engine build, even low cost conventional fluids are sufficient for regularly serviced vehicles. Even so, I do tend to buy synthetic blends and full syns. In this case I went with a full synthetic Mobil product at factory recommended weight of 75-90w. I may go with a 140w ceiling on next fill due to long service intervals of a differential.
