Installed the cover today and refilled it with one 4oz bottle of Ford friction modifier and 4.5 quarts of Amsoil 75W-140 Severe Duty oil. I thought it held 5 quarts, but I think that is filling it to the upper dipstick mark.
We filled it through the factory hole to a point then switched to the dipstick hole. With the oil between the marks on the dipstick the oil is above the factory fill hole.
This OC was Ford synthetic 75W-140 and it had 56,600 miles on it (I changed it initially at 13,300 to remove any break-in metals). The front differential, transfer case, and transmission are next.
The Amsoil seemed to be thinner than the Ford oil and quite a bit thinner than the old Ford oil. I will be sending the Ford oil out for a UOA and I will post the results when I have them. I am sure this is a "seat of the pants" assessment, but there feels like less drag on the powertrain. It is CERTAINLY going to make maintenance much easier in the future.
Thoughts and comments always welcome!
Here are some photos of the internals and the cover installed:
