A side story here:
When I bought the Ram 1500 5.7 used, I wanted to change the oil quickly naturally. I was told it had always had Valvoline synthetic 5w-20.
I ran down to Walmart and the only Valvoline 5w-20 they had on the shelf was the then new (I think) VRP 5w-20.
Shortly after that oil change, after the vehicle had been sitting for several days, on start up there was what sounded like a collapsed lifter (quite loud) that did not clear up after several seconds.
I shut it down and restarted it and all was good.
I soon changed the oil to Amsoil SS 5w-20 that I had on hand and this hasn't happened since. The vehicle sits for several days without being started all the time.
I am by no means blaming the issue on the VRP oil but I will likely not use it again.
. Done.
