SAE 80W90 is recommended by Rega. It's available at the hardware store (gear lubricant at ACE) 2 drops into the spindle. First, clean spindle and bearing with alcohol and dry with soft cotton rag.
xiekitchen- yes, your rega needs a lube job periodically. My P2 made a popping sound eventually. Rega told me to relube it with 2 drops of gear oil. The old oil had turned into black, dirty sludge. Poor lubrication stresses the belt and motor.
NO ATF or MOTOR OIL! They are designed for pressurized systems, and WILL RESULT IN BEARING WEAR. Lithium grease is a good alternative. The Gear oil worked for 20 years before my bearing seized, and there are other Rega owners in this thread who exclaimed "you have re-lube it?" so I know gear oil (80W90) works.
