Wheel Bearings:
Shell 22 for high performance (high altitude) airplanes because of its low
temperature performance.
Shell 5 for others because of high corrosion resistance and the high
viscosisity of the base oil

General airframe grease gun applications

Shell 7 for high performance again because of low temperature performance
Shell 6 for others

Gearboxes and motors

Shell 22 or what is recommended by the MM.

Don't mix greases
Keep things CLEAN.
When in doubt, use what is recommended in the MM.

I highly recommend Light Plane Maitenance The cost of the subscription will
be quickly recovered and they touch on a lot of interesting topics. It is a
must for the piston GA owner IMHO

...other than pork fat and olive oil

For those who do their own aircraft lubeing, which brand of MIL G-23827
Acft, Inst, Gear and Accuator Screw grease do you like? Why? any
dislikes?

also for MIL G-3545 High temp/wheel bearing grease.

How old are these mil specs and have their been significant
improvements
made in greases and should we consider a newer type grease??
