Would this Valvoline Synpower grease work in spicer u-joints: http://www.valvoline.com/our-products/grease-gear-oil/synpower-synthetic-grease
The grease is "moly-fortified". Some folks believe moly hurts needle bearings, others swear by it.
Nothing conclusive I've read so I figured I'd ask here where people know.
Yay or Nay?
Grease for spicer u-joints

I believe it's more important that they have grease vs the type of grease. I use moly grease in everything including ujoints
My driveline guy uses synthetic grease that is blue.
I don't know what it is, but it's awesome and withstands water contamination 100 times better than any moly grease I have come across.
DemoFly,
Could the blue grease be for bicycles?
Or even possibly marine?

When I installed spicer u-joints in my last truck I looked into this in depth. Its been a couple years but IIRC spicer actually named a cetain grease as recommended, though basically said any lb-cg #2 would be appropriate. IIRC it was either a chevron or delo version they named but I can't find that info.
I also use Synpower. It does have moly but only about 1% so I don't worry too much about it with bearings (unless they changed the formula recently). Valvoline does specifically list u-joints as an application, so I really doubt there would be any issues.
UPDATE: http://www2.dana.com/pdf/J3299-2-DSSP.PDF Looks like they name Chevron Ultra-Duty EP2.

I've read that moly can indeed cause premature wear of the rollers in u joints. I'll have to see if I can find the article that convinced me.
The evidence was strong enough that I changed out the grease cartridge in my grease gun to Mobil1 red non moly.
Spicer approved Mystik JT-6 Multi-Purpose Hi-Temp Grease:

But everyone around where I live sells it in boxes of 10.
What are your thoughts on Sta-Lube® Sta-Plex® Extreme Pressure Premium Red Grease for Spicer U-joints?

If you're concerned enough about this to start multiple posts on the topic, why don't you just go buy the Spicer grease?
