Mobil 1 oil products are a PAO base synthetic and you just can't purchase anything any better. I know that the Amsoil and Royal Purple people will chime in here but they are all just about the same. I've used Mobil 1 in the gears for years and it is a good lube.

I've been using it in the diffs of my jeep and trucks for 7 years now without a problem. I think it'd be tough for most people to tell a difference between a dino gear lube and a synthetic in typical usage but I'm into "overkill". It just makes me feel better when hammering it up a hill with the heavy trailer on the back.

Have a good one,

Go with any POA synthetic

I'll agree that Mobile 1 is a good product and I have to put in in my trans in a pinch but there are betters our there. I like Amsoil becasue of the Warranty. I also get it at dealer cost which make it cost competative to anything on the market. I also like the fact that you can run it longer than Mobile 1 and most of the other products on the market.

Without Oil Analysis I wouldn't run any oil past the recommended drain interval from the engine mfg.
On the gear lube front I've used Mobil 1 products for years and have been pleased with the results.

I run Mobil 1 in my axles, transmission, transfer case and power steering. Never had a problem and am very happy with the performance in cold temperatures as well as warm. I even run Mobil Delvac 1 in the engine.

Considering a change also. The last time I changed diff libe on an LSD/traction lock, I had to add friction modifier I purchased from F@rd (PN# C8AZ-19B546-A) is that needed for my '02 traction lock dif when switching to synthetic?

I use Ford friction modifier in my 96' limited slip while using the Mobil 1. Seems to work fine although I would call the limited a slip a unlimited slip since it doesn't do much.

I'm not 100% sure, but I think that the spec says you need the friction modifier if your gear lube doesn't meet the GL-5 spec. Mobil 1 is GL-5 rated. (I've had a couple of beers with dinner tonight though so I might be completely full of it. )

Have a good one,
