stick my head in here as a worm drive user:
my go to grease is
john deere hd moly (scrolling is required, worth the spec read to me).
i've used a few different greases over the years when i was working on combines and semi's, so when it came time to do some testing, i had some good places to start.
oregon chainsaw grease: it worked well for a long time, designed for bar sprocket use on chainsaws, it is made to take friction and high operating temps. diff area temps were acceptable.
jd sd polyurea: my general purpose grease, always have a tube loaded in the shop. i've used this on a few hundred different areas, but the diff temps were a touch high for my liking in the losi. works great in the vendetta though.
jd xd synthetic: this is some wicked stuff that performed well. i had a limited supply, so didn't do much testing. diff temps were cool, but the motor temp was raised.
jd hd moly: designed for sliding friction on construction equipment. diff and motor temps are great, and the grease lasts a long time. put it through a 30 hour torture, smelled not good, but inspection of the gears proved that only the oxide layer was worn on the worm and spool. i still use this grease.
losi great grease: about the same as the oregon chainsaw grease really. performance was the same across the board.
non-rc:
jd sp water resistant: just picked up a tube of this the other day, have not tried it out, but feels similar to hd moly. will try this next grease change.
lucas red and tacky: i have dug this red hell out of so many trashed bearings (robbing grease zerks) that i don't allow it in anything. we supplied deere sd polyurea, but some customers would still use it. bearing failure rates between the 2 were very noticable.
mystic jp-1: grease that is like an old truck. trusty as hell, but overall, nothing to right home about. great drill and tap lube.
jd sp corn head: designed for low speed 90 deg pinion gear boxes, it is a thin grease that goes to a near gear oil consistency when worked.
mobil generic grease: used in the power luber, it is much like the mystic. reliable but not spectacular.
deere aerosol lithium: have used this in rc's, but it was a grease magnet. i use this on everything from car/truck door hinges to drilling. may work in something like an ax trans, but have no clue for sure. it is very sticky, hangs on to metal very well.
as you can see i use mainly deere lubricants, the reason is that over the years, they have proven to be more reliable in more situations than many other greases. i also use deere oils and they also out perform many others, especially as motor oil. when i drain my dodge or when we drained the semi, there was no char smell, and in many cases, you could still see through the oil (not turning black in a diesel motor is what i'm trying to say, words are failing a bit). the only lube that consistently does better than deere is pb blaster. i love it as a drill lube and does better on rusted bolts than deere penetrating. i never have that much blaster around, but have a supply of deere penetrating, so that is what i use as drill lube and general hinge lubing most often.
