I have been using MFA premium 15 w 40 for several years now in all farm tractors. In the last few years I have spread oil change intervals to 150 to 200 hours. Oil samples still look good at these hours. In the new Dodge pickup I use the 5w20 called for in a MFA brand. Four wheelers and small lawnmower engines gets 10w40 in MFA brand.
