[GreenKeys] Grease and oil recommendation

[Peter Gottlieb]

I am cleaning up this model 28 tape printer and have noticed that the 
grease used on gears and other moving parts has dried up a bit.

What is the recommendation for a modern grease and oil that I should use 
to lube this mechanism?

I've used some LPS-1 to free up some gummy actions with a lot of success 
but not sure if that is a good lube for operation.
