Need a recommendation for gears grease!

[waingroo]

Hi all,
Need an advice for what kind of grease is more suitable for greasing hub gears. No necessary a brand name... I'm looking rather for the type like what base should be the best (litium? graphite? calcium etc..) Also, the best NGCL recommendation. I'll use in a brushed steel gears hub. I'm look for something not so expensive.

I pumped a lot of Mobil 28 into helicopter rotorheads: https://www.amazon.com/Mobil-Mobilgrease-Aviation-Grease-MIL-PRF-81322/dp/B00G3BTV5A.

It's also recommended for Bafang mid drive reduction gearboxes as per Karl, and it's what I use in mine.

Need an advice for what kind of grease is more suitable for greasing hub gears.

Internal gear hub, or geared hub motor? If it's the former, take care you don't give it lubricant that's too thick and will stick the pawls down. I usually use a mixture of synthetic grease and 90W gear oil, or even motor oil. Those internal gear hubs that have oil ports on them (mostly old, or Rohloff) were never intended to be greased. Don't grease a Rohloff.

If a geared hub motor, then it depends on whether there are nylon gears or not. If nylon, I'd use something like Park Polylube, a polyurea-based grease that's compatible with most engineering materials including plastics. If the gears are all steel, I'd use a moly grease.

It is actually a Heinzmann hub motor with double reduction. On the exit both gears are steel and on the lower reduction is one steel and one plastic. In fact I'd like that the grease I'll buy to work on my Shimano nexus too. I know Rohloff works under oil. I also have some brushless hub motors filled with hydraulic oil dexron II. Now, talking about a brushes, I can't actually use oil.
But, i'm one of that few guys who sustain that gears must work under oil not grease.

In some cases this is actually impossible E.g. brushed hubs, tools who wuse reduction gears etc...
