I needed machine oil and grease for my machine. Checking out the internet I found Tri Flow. I couldn't find it at Walmart or Lowe's. If I see it somewhere I will try it. They did say not to use 3 n 1, which I have been using for a long time, lol. The grease goes on my ESE 2 which is 25 years old and has started squeaking on the bottom bar. I have put that embroidery machine through tons of work and it is still going strong.
