Why are you using 5-W-30 oil, when Ram specifies 5-W-20 viscosity?
This might interest you.Read the note at the bottom,and you'll also notice nowhere do they claim 5W-20 is best for the longevity of the engine,they only say it's best for milege and cold weather starting,you can be damn sure if FCA thought 5W-20 was best for the engine longevity they'd be touting it to the moon and back.This is from the 700 page printed owners manual for my 14.There also seems to be less cam/lifter issues with 5W-30 . Alot of us are running 5W-30 with no issues.
