I can't say enough good things about Tri-Flow oil and grease. A few months back I bought a 1915 Singer treadle that had been sitting around a LONG time. I oiled it with Singer Oil and Singer Lubricant and I got it working. I thought it was doing pretty well and then I tried the Tri-Flow products and the difference was amazing. I can tell you that it was MUCH easier to treadle after the Tri-Flow!
