Record changer slowing down

I have a Zenith Moderne Z565 record changer.

When I got the unit I immediately ordered a new idler wheel, lubricated the arm and platter mechanisms, and took apart and lubricated the electric motor. Later I changed out all of the resistors and capacitors. It worked perfectly for about 5 months, until it started slowing down.

I have a single, very dry, gas heater in my apartment. It's in the same room as the turntable. I started to suspect that I'd used the wrong oil on the motor and that the dryness and temperature fluctuations had started to solidify the lube, so I took it apart, cleaned and re-lubed the motor using a light turbine-oil.

The speed improved for a couple months and now is very slowly degrading. If I had to guess, because I don't have a strobe, I'd say it's playing at 29-30 rpm.

Does anyone have experience with an issue like this?

My guess it was not originally designed to be run using a light oil. Friction of motion alone will help to dissipate it. Also not knowing how the well is designed, if it would hold it for a long period. I would try a light grease, Vaseline comes to mind, and see if it improves.

Grease is my guess too. Alternatives to petroleum jelly include gun grease and the lithium grease used on auto door hardware.

All from the advice of audio forum posters, for the arm and platter mechanisms I used Super Lube 21030 synthetic grease.

For the motor I initially used Super Lube 51010 synthetic oil, but then replaced that with LA-CO zoom spout turbine oil.

I'll try grease on the motor.
