Now that's the kind of post that makes this site truly interesting and worthwhile. Bob, your expertise is appreciated. My Gyro SE comes with a thimbleful of oil, which can be replaced for a mere $15.00. As an engineer, I was quite certain that Michell doesn't have a refinery create a unique oil for their application, and that any motor oil would think it was on vacation circulating around in my turntable. Thanks for confirming my suspicions.
Home Spindle Lube Test
In anticipation of an phono preamp switch I gave my 30+ year old Dual 1219 turntable a lube job. It's rim drive so the platter spins freely with the drive disengaged. The test involved only common household lubricants that have other uses.
Procedure: clean the mating surfaces with 99% isopropyl alcohol; lightly lube all sufaces using Q-tip; spin platter by hand at high speed for a few minutes.
The test (taken at 58F degrees room temperature): Engage drive at 33 1/3 then disengage it, noting how long it takes the platter to come to complete rest. I repeated each test once to verify the result. The results in the order tested:
Light machine oil - Gunk Household oil: 105 seconds
Bicycle bearing grease - Castrol Synthetic: 65 seconds
Automotive motor oil - Mobil 1 grade 0W40: 160 seconds
Note: when mounting the platter on the spindle, with Gunk the platter seemed catch as it slid down. On dissasembly, the Castrol had coated the surfaces reassuringly. I left the Mobil 1 undisturbed!
