I'd be concerned about using ANY kind of lubricant that would attract or hold dirt, carbon particles, etc. Clean the advance weight pivot points and either leave them dry or sparingly apply something like a dry film lube. Powdered graphite could work - if it wasn't conductive. I have a spray lube that has PTFE (Teflon) in it - the carrier evaporates and leaves the PTFE behind. The one I have is by GUNK Liquid Wrench, but WD-40 makes it, as do B'Laster, 3-IN-ONE and probably every other maker of general purpose lubricants.
