Is there a fundamental problem with the formulation of Redline oils? In many areas Redline has a good reputation, but I havn't seen a really good UOA for any Redline product. There doesn't seem to be any advantage for extended drain intervals or wear reduction. The motor oils even seem to exhibit more wear than a dino oil. Is the polyol ester base stocks simply not a suitable base for lubrication in an automotive application? I am NOT bashing Redline products, just trying the learn more about lubricating oils.
