Gear Oil Help

I'm trying to decide which gear oil to use in my differentials, transfer case and manual tranny.

I found this analysis online, but I'm not really sure what it all means. Can someone translate this into english for me?

Is this a valid study? If so, what brands are good and what brands should I stay away from?

 

I used royal purple in my 05... a little pricey but has a good rep with the off road world. I also noticed my truck drove smoother!

 

Okay, at the bottom, they are saying that AMSOIL is the best.

 

It looks like RP didn't do so well in some of their tests?

 

thats strange... i know a few people who run it and never had any problems? and i am starting to here good things about amsoil!

 

I seems like people either love or hate RP, so I'm staying away from it. I've been leaning towards AMSOIL for a while, cause I've heard nothing but good things about it.

 

When I do mine, im doing mobile 1 synthetic in the diffs and transfer case and redline mt90 in the transmission.

 

well im a believer in RP... but im sure the amsoil is good shit also! haha... i never had any problems! knock on wood.
