[GreenKeys] Lube

[Michael Zahorik]

Nick, thanks for the info. Both of my machines were pretty junked up. I've been cleaning them and oiling. I'll try your suggestion.

I've been using 0-20W synthetic motor oil on five Teletype machines
since 2008 without problems.  Synthetic motor oil is all one
molecular weight - there are no heavy fractions.  Most oils are
a mixture of various molecular weights, from very light down to
asphalt.  This is OK at first, but the light fractions evaporate
first and leave the tar and asphalt components behind.

There are synthetic machine oils, but they tend to retail
in tiny containers with excessive prices and come from
vendors you never heard of and without a chemical composition
listed.  Full synthetic motor oils aren't that expensive
and are easy to buy.

It took me weeks to unjam a Teletype Model 15 which someone
had lubricated with an oil with heavy fractions, then
left in a garage for twenty years. See:
