Hi Ken, Tri-Flow Grease is great for putting on *gears* because it's "sticky" and stays put longer. The older type of grease is gradually, if not completely, thrown off by the motion of the gears, like shaking water off of your hands.
However, you probably don't want to use Tri-Flow grease in a motor's grease tubes where there are wicks involved. Reason being, the way those operate is the wick is supposed to transmit the grease down to the axle; but Tri-Flow grease contains little bits of Teflon--the very thing that makes it sticky and good for gears--and there's some debate as to whether that Teflon actually clogs the wicks and therefore doesn't get down to where it needs to go. If I'm greasing a Singer motor's grease tubes, I always use Singer grease (or Vaseline, which is the same consistency).
hope that helps,
