restoring a technics linear tracking turntable

My Dual 1219 platter kept spinning twice as long after shut-off using Mobil 1 when compared to light machine handy oil. I now use it on my Nakamichi capstan shafts with complete confidence. It's not grease but its man-made molecules are of uniform length. Imagine long ribbons that can slide over each other. As they work they get chopped up. By comparison, conventional oil is a collection of long and short ribbons so they can't work as well or last as long.

Thanks everybody for all your help.I think
I'll try Mobil 1 oil and see what happens.

Mobil 1 is a bad idea. The rail is not sealed, and the oil will attract dust. Also, the oil is more likely to migrate to other places it is not desired. Too much oil, or grease, and the slow downward cuing of the arm will be lost. For the rail, I use Part # VFKS0081 GREASE from encompass parts distribution at http://www.encompassparts.com/products/?MSCVFKS0081.

Very, very light coating is all that is needed.
