Be careful with Dubbum-D 40. It is a not really a lubricant, but rather an extremely light petroleum fraction that will act as a solvent for other oils and greases. It frees stuck machinery by dissolving the hardened, old lubricant and diluting it.
Its primary purpose is to displace water (hence "WD"--"water displacer").
Clock-repair technicians routinely double (or wish they could) the repair estimate of clocks that sport the distinctive WD-40 aroma. That lets you know what they think of it. I use it for freeing up old machinery, in the same way I'd use penetrating oil, but once freed I clean it and lubricate it with something real.
Pam would be a better lubricant! At least until it went rancid.
