[GreenKeys] Lubrication

[David Christ]

I agree on the 3-in-1.  My wife has an uncle who has repaired sewing 
machines for decades.  Some manufacturers would void the warrantee if 
you used the then common 3-in-1. It had a tendency to get gummy. 
Whether it is true now I don't know, but it was rumored that the 
original 3-in-1 had a vegetable rather than a petroleum base.
