FWIW, I've updated the Amsoil Page on my Website with the following:

UPDATE (7/15/2007): Well, I'm just about at 30k and I've changed my trans and gear oil. I stuck with the same Amsoil products. What came out was incredible. The stuff looked almost new, it was that clean. I wish I had pictures of the drain plug magnets this time (sorry, my digital camera was not available) because there was very little particulate matter on them. There was a bit of "slush", but I would always expect that. So, we have one of three choices (that I can think of anyway) to choose from:

1. The Amsoil is doing a great job and keeping the gears from wearing as evidenced by the lack of material on the magnets.

2. The original 9k wasn't long enough to turn the particles into slush.

3. All of the "heavy" wear had already taken place within the first 9k miles.

It's likely that 2 and 3 are the "most true" statements, but I was very pleased with what I saw at these oil changes. I may change the oil again at 60k, but I think it's more likely that I'll give this batch at least 50k miles (80k on the odo); keeping in mind that the maintenance schedule for the 2wd doesn't even call for a oil change; only inspections.

Finally, it could be my imagination, but the transmission does seem to shift smoother. I don't really understand that. I didn't notice any change after the first Amsoil change. I can't believe there was enough of the original oil in there with the Amsoil to make a difference. Guess I'll see how it behaves when the weather cools.

I just changed my front and rear fluids with amsoil 75/90 I only have 900 miles on my 07 but I wanted the factory stuff out It is amazing how much ground metal those drain plug magnets hold. I also installed magnets on the oil filter and transmission.

I have an 03 and changed my front and rear diffs at about 44,000 miles. There was a lot of build up on the magnetic plug. I have the LSD in the rear. One thing to note about the rear orange tag is that it was covered over with undercoating and could not be seen so I had to scrap of that undercoating to make sure I had the LSD.

W/ the LSD you need to get the additive with the differential fluid. However, I used royal purple for the rear and front and no additive was needed. royal purple is more $ but has longer wear strength than a standard diff fluid.

This processes of doing the diff is so easy even a "caveman" could do it. However, it's better if you have an air gun for the front (at least on V6 model).
