Are there polyurea greases with Molybdenum?

[ChrisJ]

I thought this would be easy to figure out but,
Are there any polyurea greases with Molybdenum, or are any greases containing Moly going to always be lithium?

what exactly is your application??there are many good greases, Shell used to have a grease called Moly/Poly,a few years back,,,,I would think a regular polyurea grease as Schaeffer's 278 or 274 ,or Cenex (made by Axel) Poly Extreme would work good but has no moly,,,,,,,,,,,,,or Swepco has their 101 grease,, or ,,,Royal manf. Lubrication engineers etc etc ,,,,,,,just do not mix polyurea greases with other thickeners,, for most situations try Mystik lithium complex grease as their low temp,synblend #2 (blue color) grease,operating temp of -27f to 325 operating temp,drop of 500f,,timken load of 60lbs GC-LB approved,,, fantastic stuff for a lithium complex grease.

I'm working on a tool that has grease that I know has moly in it, but I don't know if it uses a lithium or polyurea thickener.
In reality, it probably doesn't matter since I'm cleaning 90% of it out, but it made me curious if all greases that contain moly use lithium.

This is more of a curiosity than anything.

a good 3% grease maybe is the schaeffers #274-2 aluminum complex ,or the mystik synblend mentioned above,,is it a high speed or heavy load ??, moisture interactions?

It's a corded Milwaukee sawzall.
Moisture is doubtful but possible, I suppose load could be high but I think speed is low. The best description I could get from the oem is that the grease used has moly in it, is a NLGI 2 and the old stuff is a dark grey color. Milwaukee calls it their type T grease.

I was planning on using Magnalube GX as we have it on hand for other uses and it's a NLGI 2. I'd assume it far exceeds any requirements in such an application?

just stay with a polyurea grease would be the way to go,little surprised its not a NLGI 1 though, or see if you can get it from the manuf. but maybe pricey. check with Great Lakes Power tools,1-800-341-3567,,it may be either Type A or E grease.though this maybe best choice .Super Lube has a squeeze tube grease that might work too.

I also keep Magnalube G in stock which is Polyurea/PTFE grease, also NLGI 2.
But I thought the GX would be closer to whatever the original stuff was since it has the addition of Moly like the original.

Can't find much info on it besides it being a mineral oil as the fluid and containing both a Teflon and Molybdenum compound. I'd probably buy the 1 lb tub available online given the clean out and changeover difficulties for switching greases.
