In this video in particular he says it will throw a code: (@6:05)
This video in particular, a 10 year Mopar mechanic, is why I ask the question in the first place. I am going to do the RL 5w30 / Royal Purp filter regardless, I have nothing to lost at this point.
That's the benefit of Ram forum, we have likely 100 historical users of redline 5w30 with no codes thrown over as long as a decade, and 100's of ram forum members using other 5w30's with no codes thrown. maybe you will or wont get a CEL, but I'm wondering if that code has some allowance different states of viscosity, so the code gets thrown on something heavier then 5w30. Anyhow, the overwhelming evidence is 5w30 redline is a known tick killer, against the off chance you would get a oil code, the decision is yours.
