Agreed. It really comes down to this: speculation vs fact. What do we speculate is true, and what do we observe is true. I couldn't care less about the speculation to be honest; but if you quiet your engine by changing the oil/filter, that is a fact that should weigh more in your deliberations than what we think Ram is doing and why they chose one oil vs another or if they are aiming for 5 years of life vs 15 or whether there is some cam/oiling flaw. Fact is fact, and quieter is a GOOD THING, and nobody has shown any evidence to claim that Redline is a bad oil (blackstone analysis comes back and shows less wear than before). At that point, what is your problem? Why go off about zulus and pookies? I'm really confused by that response.
