just a tish NE of central ND | Im no help on your question, but I can tell you I bought some straight #10 for our old M IH to winterize it and the stuff from TSC was very thin and runny compared to the cenex #10 oil at the exact same temp. The TSC stuff was clear oil and looked like vet grade mineral oil you use to give a pluged cow.It was the color of clear silicone. |
