Lots of yacking, mudslinging, and inferences yet no one has:

!. Found the root cause,

2. No one has asked Amsoil to comment.

Under what conditions has any one fluid supposedly failed - tracking or daily driving; what was the fluid change interval, what did the UOA's show?

I have seen causes of differential overheating due to incorrect bearing and gear pre-loading with shims that did not provide the proper loading.

Could it also be that the bearings, ring and pinion gears are undersized for the torque developed by the engine?

Where do you get the Delvac 1? I've been considering migrating from Mobil 1 to this for some additional protection for loose sand work in the Florida heat.
