Tri Flow Superior Lubricant 2 oz bottle
Don't be confused by the word lubricant in the name of this product. On a Singer Featherweight, Tri Flow is used just like oil and in the same places as oil. The benefit of using this product is that it clings and is not thrown out as fast as the Singer oil products.
The places where lubricant are used is the creamy thicker type of lubricant is still correct.
