That should be Tri-Flow oil, not trip-flow and we also like Tri-Flow grease. It's a great product for gears such as the fiber one on the hand wheel and it's drive gear. Does wonders for any steel gears too. You can get both at Sew-Classic.
Use motor oil on the top of the motor shaft bearing, and run the machine after you have put the oil on it. That way the oil can work it's way into the bearing and soften the old hardened grease.
Use sewing machine oil or Tri-Flow oil everywhere else you oil.
In lieu of the Tri-Flow grease you can use the white colored Singer grease that's available now. It's for gears. The old motor lube in the tube will work too, but not as good.
