Thanks to all - based on responses received and my own further reading, I have settled on the Lucas #2 Red n Tacky grease and Valvoline 0W20 synthetic oil for the M15.... time will tell how well it works in the running machine.

Some time ago when I first got my model 28, I either read or someone recommended to me these:
Valvoline 0W-20 Synthetic and
Lucas #2 Red & Tacky

Works for me...

Subject: [GreenKeys] M19 Lubricants?

At the risk of sparking a war of differing opinions, I am in search of a recommendation (perhaps even a consensus?) for a modern-day oil and grease to use in re-lubricating my freshly-reassembled M19 mechanisms.
I know I am looking for a light-weight mineral oil similar to the Teletype KSxxxx oil, and suspect that a white lithium grease will serve as an adequate substitute for the KS-spec Teletype grease.
Beyond that, what should I use to re-lube the M19?
