Peter --

If it's the little clock, to the right of the main cluster, you simply pop out the bezel and slide out the clock. It's held by three small rubber "grippers"—but don't lose 'em!

If it's the big clock in the cluster, you remove the cluster and then remove the screws securing the clock to the printed circuit board.

Lubrication is probably the WRONG soultion — and if anything, may cause problems (oil becomes viscous in the cold). Instead, replace the capacitor in the clock electronics. You can buy a replacement at Radio Shack. Get the same mfd value (or slightly higher), and be sure you buy one with a 15-volt or higher rating. Make a sketch of the polarity (+ and -) of the original cap, and be sure the replacement is properly polarized when you solder it in.
