Thanks for chiming in.
Looks like Motorcraft 5W-50 shears from 30%-38%
Amsoil Shears 1%-4%

Motorcraft Virgin Viscosity to Used Viscosity - 19.9 - 12.5
Amsoil - 10.5 - 10.1

Might I also add that the motorcraft results were from an engine with 3,800 miles
The amsoil was with 38,000 miles

lol... Just saying... Motorcraft is not great oil. Its sufficient
