Regarding oil for lubrication, it is important that it should be "non-gumming".
Motor oils like 10w40 meet this requirement, and have been recommended a lot
on forums like audiokarma. I have used it for my Dual 1229 restoration too.
I understand even good sewing machine oils are non-gumming, so should be ok.
Many of the service manuals quote old, outdated products by brand. For Dual, I
found this info which gives modern equivalents for the recommended lubricants -
Renotac No. 342 Adhesive Oil
Use Automotive Synthetic Motor Oil 10W-30W
BP Super Viscostatic 10W/30
Use Automotive Synthetic Motor Oil 10W-30W

Use any White Lithium Based Grease with the consistency of Vaseline, but don't use Vaseline.
(Shell Alvania #2 is a general purpose lithium soap grease with a useful temperature range
of -40 F to +280 F. EP2 (LF) grade.)
