The Chinese Weasel Grease is all gone...what's the secret sauce I want to use instead?

I usually have synthetic lubricants around the home for brake jobs and other lubrication chores.
Pick a pretty color.

About $4.50 for a 3oz. tube

For some reason Super-Lube didn't run real smooth in my CG-5. I stripped it and reloaded it with acme thread grease I got from McMaster-Carr (Nook Industries # NLU-1001). It is a terrific low speed surface bearing grease. My worm gears I have lubed with high PTFE synthetic bicycle grease $$$.
In most cases, where SuperLube Grease hasn't performed up to expectations, the problem is that the prior lube wasn't completely removed. A toothbrush dipped into mineral spirits is the usual drill, and I've redone mounts where it took three or four passes to completely clean the gear teeth. IMHO, mineral spirits is the ONLY acceptable solvent (with the exception of the incredibly expensive Tower 99) to remove grease. Acetone, lacquer thinner, and soap-based products aren't. MEK is OK in a pinch.
If the bicycle grease works for you, fine, but I doubt it has the additives appropriate for helical gearsets. ACME thread grease may work, but ACME threads are cut differently from standard threads, and are generally designed for intermittent use, an application completely different from worm sets.
Mobil makes exceptional products, however, its synthetic grease has a Lithium soap-based thickener, with its drawbacks for astronomy.
BTW, I'm a recovering lube and fuels engineer (with a major oil company), and spent 30 years in the Navy Reserve as one of two nationwide...my mantra is: "Oil's cheaper than metal."
You pays your money and you makes your choice...

Makes sense to me, that would explain why the Super Lube worked well the first application but not after I tried the acme screw grease. Next time I've got reason to be in the mount I'll try a little more rigorous cleaning, I probably missed some in my last stripping as I really like the idea of high PTFE greases. I did misspeak, the bike grease I'm only using on the reduction spur gears.
