In my work overhauling various products, I've gravitated to using synthetic grease for many things.
It sheds water/moisture better than petroleum greases.
It doesen't attract dirt.
And it seems to last forever without hardening or drying out like pretroleum does.
In the shop over the years, I started using "Super Lube" grease on things like VCR mechanisms, CD mechs, Turntables, etc.
And at home on power tools, mechanisms, etc.
30 years ago I serviced my old VCR's with that grease, and just a few years back did an inspection of them - they worked fine, and that grease was still slippery as hell.
It's also great to pack bearings with.
That turbine oil is great too.
As for heavy oils, I like the 20 weight engine "break-in" oil with the zinc additive.
