Lubricants, rearend differential and transfer

[1983gsp]

I was at work today secvicing the high speed pumps we use and started wondering about the oil I was putting in the gearboxes. They are pumps used to transfer water and lime sludge from one tank to another or from the plant to a retaining pond. These pumps handle a lot of water, over 1100gpm+ @ over 100psi. The gearboxes seem to never wear out over the 4 years I've been here, running 24/7 365.

The oil is called iso150, fully synthetic gear oil. I researched on google and this is what I came up with, Schaeffer Oil | Universal Moly Gear Lube #209A

Need some oil guys opinion on this stuff. Looks like it could be a winner for our differentials and transfers, and maybe transmissions as well. No need for the redline is proven or just run what everyone else is running comments.

Let the discussion comense.

I would not put a single-rating oil in the rear or transfer or anywhere else. Your car sees quite a variety of temps. Something with a wide range, such as 75-250 (e.g., *cough* Redline Heavy Shockproof *cough* ), is the kind of gear oil that you want.

talking oils is like talking religion, politics, or OS's. you will get way more opinions then facts. simple answer is if it seems to work good in something and has no corosive agents to any of the metals in the trans, it might be worth trying, but then, are you up for the possible side effects if it fails? with that said i think single weights are generally fine and have ran them in some EXTREME engines.

to point that out iwould NEVER run a wide range rated oil in anything i own, IE: something with a 75-250 rating.

What kind of opinions are you looking for with this post? Redline IS what a lot of knowledgeable people run, because it IS proven. Asking for us to post our opinions, but only if they don't include any mention of the most popular lubricants that are known to work well is a bit useless, don't you think?

BTW - I run Redline Heavy Shockproof in the rear end and transfer case, and Redline MT-90 or 75W140NS in the trans... because it's proven to be damn good in countless 600+ hp cars.

Heavy shockproof in rear and transfer case. MTL and MT90 mix in transmission.

I'm sure you can call in to change the fluids out for the rear and xfer case.
