[GreenKeys] Lube

[Nick]

My personal opinion :

No matter what oil you are using, you still have deal with the fact that dust (office, household, carpet and especially paper dust) will thicken the oil over time.
Depends on usage, soon or later you have to give your equipment a good cleaning and re-oiling.
Of course, later is better, right? Therfore, a good quality synthetic oil is probably the answer.

    I wonder if this mixture is true for single weight oils. Engine oil
has additives in it such as detergents, not sure if they are necessary
or desirable for general machinery.  Kano Labs makes a good, highly
refined petroleum based oil called Microil, about 20 weight, might be
good for this. Not supposed to gum up. There are also synthetic oils
available at hobby shops specializing in model trains. I've used LaBell
brand but, as you say, its expensive and comes in small containers.
    I wonder what service is required by a Teletype, i.e. high or
extreme pressure oils or just plain high quality machine oil.
