So I’m 1.5 hours in (3/4 finished) with the 540Rat blog. Amazing how smart this guy is. But stumbled upon this.
Those of you persistent about using 5W30 to try and prevent lifter failure are wasting your time.
Assuming based off his analysis all we can do is just GUESS when a lifter is about to fail and get it replaced before it causes serious engine damage?
He does mention that 5W30 could potentially assist in engine noise due to being a bit thicker, but apparently we can’t do anything to prevent lifter failure and it’s good to know idling isn’t a bad thing for them! I thought idling was bad for Hemi lifters.
In the end, if under warranty, we’ll still be questioned and potentially blamed for this due to oil or change interval etc etc, but the truth of the matter is, OIL/Filter play NO ROLE IN LIFTER FAILURE!
