Unacceptable gearbox wear

I have been seeing engines lately with unacceptable gearbox wear (in the dog gear). So far, these have all been using Aeroshell Sport 4 oil. I have never seen a problem with the gearbox using Mobile 1 4T oil. I would like to hear from anyone who has seen the wear, and what oil was used.
