Being this is BITOG & Christmas, I thought it appropriate to ask! Problem is...there's no oil forum for gyroscopes. It is an Asian model, so perhaps "import" is appropriate? Looks like a metal pin on plastic bushing combination with a touch too much in clearance. I may be able to adjust it out. Definitely a high-speed, very low friction application here. Oil? Grease? Silicone? Graphite? What weight? HTHS? Suggested OCI? MTBF? Using a Moto-tool and a rubber wheel, one can get the gyroscope wheel spinning incredibly fast!
