| Local supplier has Mach 4 UTF pretty cheap. Salesman says he has total confidence in it. Has anyone sent in a new or used sample for analysis? It is supposed to meet most specs. It meets my tractors specs. I prefer to see the additive levels myself. You would think oil suppliers would hand you an analysis on request but they dont. Sone will tell you it is a trade secret. The specs are no secret why should whats in the oil be a secret. | |
