Floor jack maintenance questions

[RoundedCorners]

This might be a dumb question, but are there any recommended greases, sprays or hydraulic oils that are recommended over the others? There's a good chance that I'm over-thinking this.

I assume(?) that pretty much all NGLI greases are the same, and #2 being the standard.

Are "dry" sprays OK?

Is it worth getting something like "Bar's Leaks HJ12"?

#2 grease should be fine.

As far as hydraulic fluid I use special "jack oil" it has some type of additive that swells the seals to "fix" leaks. If I rebuilt one I'd probably avoid the leak "fixing" stuff.
