I'm surprised no one mentioned this, but if my oil was coming out clean looking at 10,000 miles, but another brand looked dirty at 3000 miles (with the same engine) I would seriously wonder if the brand that looked good at 10,000 miles had enough detergent to clean my engine properly?

My implication that Mobil supplied Amsoil is opinion as I have no documentation for that. Gulf and Mobil were the only two patent holders at that time for the process. So PAO blendstock would have to be either supplied by them or by a company to whom their technology was licensed to. I would be willing to believe that Amsoil manufactured PAO base stock under license from either one of those two companys just as soon as someone can name and document the location of an Amsoil refinery.
As to your observation that "mobil always seems to not hold up quite aswell as the amsoil", no fair and scientific comparison can be made because Amsoil is not API licensed and Mobil is. So Amsoil is free and unencumbered by any standards when it comes to additives. Sort of like you cannot fairly compare an athelete who built their body with steroids to one that did not.
Gulf Oil was once one of the major oil companys. In 1986 they merged with Chevron USA. The trade name Gulf survived only to be sold and is held by a marketing company with no affiliation to Chevron.

F250_, you clearly have done your homework. i would like to go shaeffers 9000. not just the PSD owners but big rigs swear by the stuff and the UOA i have seen show it to be the best period.
where did you purchase it?
as for your amsoils experiance you are among many with the same results.
amsoil < all others
like i have said before, best of luck with the amsoils.

Well, to be honest, killaford, I had excellent success on Amsoil with my '96 Suburban and '85 F150... just wasn't as happy as I thought I'd be with how it worked on the PSD.
If you go to the Schaeffer site, ther is a link to find "where it is sold". Use your zip code, and it will direct you to a list of closest dealers. If nothing is nearby, call their 800 number and they wil either direct you to a regional rep who may live close enough to work with you, or they will do the same themselves.

A) Drain as much oil as you can (perhaps have truck at angle for gravity assist) and change oil filter.
B) Drive 3 k miles, send in sample.
C) change oil and filter, to same brand/type oil and new same/type oil filter.
D) retest
E) wash, rinse, repeat
F) try new filter / oil combination
F) wash, rinse repeat
The point is to use first cycle as a 'wash/clean' and pay more attention to the second cycle. Go a third cycle on same oil/filter combo if you like. Then change oil/filter to different combo.
IMPORTANT: If at ANY POINT you see a 'dangerous' situation in a Used Oil Analysis (UOA) immediately take the appropriate actions.
