Mobilgrease 28 Aviation Grease, 13.7oz, MIL-PRF-81322

Very good deal for the price. I use this on bearings for an industrial dust collector that sits outside in the weather all year long. I've heard some guys use this as a replacement for isoflex grease in crank bearings. I haven't tried that yet but it would probably work. Very high quality product.

I got it for here at home to do my garage door (runners, chain, etc.) and then put a dab on my car's sunroof and the drawers on my old roll-away chest. Everything is working better now and smoothly sliding quietly. The garage door went from squealing to quiet and is as smooth as glass. I chose this grease since it's what I worked with when I worked on aircraft actuators (commercial and military) as an engineer. I've personally tested this grease to military standards from -65F to 350F and it works flawlessly in that range. At -65F, I cold soaked my test article for 4 hours. When I applied power, it broke away without a hitch and started moving as required, even when I had added a ton of water to the test setup, this grease still broke free and moved smoothly. Performance at high temperature was never in doubt, it worked perfect. That's why this is used. If you've ever flown in a plane, you very likely had Mobil 28 in use all over the plane. The other one we saw use of is Aeroshell 7, but Mobil 28 was our more common. It's well regarded for staying where you put it. It migrates with moving parts as it should, but it doesn't splatter or drizzle off, etc. Can't recommend this grease enough. My parts are flying with it on military aircraft, so it should be fine for your regular uses.

From what I read online, it's recommended to replace the factory grease in Baofeng BBS02 ebike motors with this grease at or before 1000 miles for all motors, or immediately if your motor sounds a bit louder than it should and may not have enough grease from the factory. I did this at around 1000 miles and my ebike is now at 3500 miles with no motor issues, so seems to be doing its job. When replacing the grease, just wipe off as much of the factory grease as you can, then pack is much of this into the gears as you can, like you would when packing a wheel bearing. I still have a bunch of it left and it's good quality, so I'll probably use it for my car and other tools that need grease.

Worked fine for my ebike

I like this grease because it stays where you put it. It doesn't turn runny and ooze away from the gears where you need it. This grease is made for aviation motors and gears where you need dependable products to keep your plane in the air. This really is the best gease for ebike motors because they work hard and get hot.
