Get on the phone to FotoCare, Oslo and ask them for help. The head tech, Mr. Vegard Kvamme, tends to be very helpful. He probably could arrange for a small vial of the proper lubricant to be picked up at their site. Or you just drop off the lens there.
Do note that this particular Micro-Nikkor has a nasty reputation for its propensity to get lubricant smear on the aperture blades. Thus regreasing should be done with the correct lubricant and utmost care.
