Hmmmmmmmmmmmmmmmm...................
I'm at almost a 100k on my modded stroke. I wail on this thing and have since day 1. Always run Amsoil Diesel rated oil as well as other fluids, along with the bypass filter system. Didn't do a complete drain until 50k, and again just a week or so ago.
I won't dispute "your" claim but I have monitored the diesel forums for the last several years and have heard nothing like your statement, ever. Frankly I have never heard of Amsoil products being the reason for failure although Ford rarely takes responsibility, always looking for a scapegoat.
Proving fault will be easy if you have documentation of the product used, oil change frequency, and of course lab samples of the fluids from each drain. But if ya had all that, you wouldn't have a failure, or at least it wouldn't come as a surprise.
I'd like to hear what the problem was that required a replacement.
Repeating what was posted earlier, Amsoil is a very reputable company and product line. Many don't like the MLM program and assume it to be snake oil as a result, take a good look at the entire product line, the houshold items, and Hastings filters and then make your decision.
Good Luck Eric!
