In my manual it has a recommendation in one section for ONH-68 oil in the headstock. However, at the back of the manual in the cross-reference for oils and lubes, it only shows recommendations for ONH-32 and ONG-68 (which is mentioned elsewhere as the spec for the way oil). I was going to find some ONH-68 equivalent, but now I'm a bit confused on whether that's a misprint.

What oil do you guys use in the headstock?
