And another grease question, but for a mixer.

I need to repack the gearbox in a KitchenAid mixer soon, I'm noticing the factory lubricant is leaking from the mixer planetary and the body is getting warm when I use it. Whirlpool used a clay-based grease to get the mixers off the factory line and they do recommend repacking as part of routine service. It needs to be food-safe grease.

Amazon has Ultra-Lube Food Machinery grease, seems to work well, bio-based "synthetic":

Zoro has a Mobil NSF H1 certified grease:

The main differences is that the Ultra-Lube is a bio-based grease and the Mobil one is conventional mineral-based and has a thicker base oil(ISO40 vs. ISO220). Should I just get the grease off Amazon and call it a day when it arrives?
 
I just looked at it - looks like some are using Tri-Flow or Amsoil grease, but I tend to avoid Tri-Flow based on my experiences with it on bikes.

The KitchenAid mixer motor/gearbox does remind me strikingly of a Chamberlain/Lift-Master chain/belt drive garage door opener, doubt grease will migrate into the motor from the gearbox.
 
A lot of people I have seen use Ultra Lube, I went with KA grease. It was like $20 and it's food grade and also gives me some peace of mind, nothing else

How big of a KitchenAid?

When I did mine, I never thought to look into "food safe" since it doesn't leak, anyway. I used a moly grease with about 1/4tsp of STP.

It's a 300W 3.5 quart one from the late 1990s-mid 2000s. I'm seeing some of the OEM pack leak out from the planetary.

The gearbox is encased in plastic from what I've read. The gears are metal.
 
It would be nice dedicated foot grade grease. Since everything is under enclosure I would go to low cost low fortified grease. I assume that you already have something similar at home.
I living in Europe and I already have at home Total Ceran XM220 – Calcium sulfonate grease. Most Ca sulfonates greases are almost free of additives and many are food grade certied.

IF you really want Food grade grease - "Dow Corning 111" it is available in amazon.com.

Advantage is that is silicone based – friendly for plastic bearing or gears.
 
Turned out I had some NSF-H1 certified grease on hand - Loctite's ViperLube, a Ca-complex PAO grease. I used the the whole tube for the gearbox but I ran out. I ended up using M1 grease in the lower planetary, that way if it leaks I don't need to tear the whole mixer down, just the planetary gear if I need to relube it with food-safe grease.

The mixer seems to work as usual. I might have underfilled the gearbox.
