Is this stuff any good for a Ford differential that calls for 75W-140 Synthetic? It is about half the price of Motorcraft or Mobil-1. I change the diff oil every 50,000 miles and don't really see the need to spend the extra money if I don't have to.

PAO based. I'm using it my Harley transmission. It's working good so far.
