[Help!] Lubrication of 9v motors?

[Rail Co]

Hey all! So the other day my package arrived containing the 4563 Load N' Haul from 1991 and the 7722 Cargo Train from 1985!, this is beside the point. Today I was removing the traction tires on my 9v motor to clean them (junk like dust, dirt and hair was caught in them). But before doing so I relized that almost my whole motor was layered with oil! So i cleaned that off and put it back together. The problem is I am wanting to make sure that there is still enough oil to not have the motor be damged by not enough oil. When I run it it doesn't make loud squeaks or anything it sounds normal. Anyone have tips on oiling/knowing when to oil your motor!

Thanks guys!

The 9V motor is mostly plastic gears, so lubrication isn't strictly required. That said, if you want to lubricate them, a silicone-based thin lubricating oil is probably the best choice.
