So I see that many past popular oils are still not approved by Ford for use in their vehicles, specifically their 6.0 motor. What's the general consensus on what to use? Should I just use Delvac, Valvoline, M1 etc off the shelf and don't worry?
Ford say's we'll kill our engine but the oil manufactures are touting less wear.... What gives?
