Morning
@Burla,
Been reading through countless oil, oil filter and lifter threads since my recently developed failed lifter.
To keep to topic; redline is expensiveAF (I know, how expensive is the cost of not having good insurance) just weighing my options before religiously switching to a $14/qt oil for the rest of my truck’s life. (Absurd!)
I saw you said M1 fs 0w40 is super class, thinner, and missing out on ester base and additives.
Is there a better than M1 not as expensive as RL option (for the hemi)?
I’m coming from PUP 5w20 with fram xg10060
I’m planning on installing a hellcat oil pump while I’m in there with the 50psi bypass spring to up idle flow. Still debating if I want to go to rp oil filters. A change to the fram xg10575 for sure at the least.
Thanks everyone for all the documentation in the various threads. Life saver for ignorant owners like myself.
Best ,
James
P.s.
Read another post by burla - gonna just try RL 5w30 rp 20-820 what can it hurt (considering I was planning on spending 2k to do the fix).
Leaving my original post for transparency.
