Visit www.kaaz.com. They clearly state that synthetic is NOT RECOMMENDED for their differentials. The performance will be greatly diminished. The diff was designed for natural oil. If you don't want to use the kaaz brand oil, just use cheapo valvoline with ford friction modifier. That's what I'm using right now, and I think it works just fine. Plus, you can get all of that at autozone for about 10 bucks, instead of 50 for the kaaz stuff.
