@AutoMechanic what's with the sad reaction emoji dude? That 0W-20 has a robust Euro additive package and it had an ending visc of 9.5cSt in my most recent UOA, which is heavier than a lot of xW-30's we see on here:

Wow, that HPL flavor is robust indeed!

I didn't vote because I don't own one, but I would run 5W-30 if I did. I lean on the thickie side these days.

I ran 5w20 in my 2016. Eventually I started using Lubegard Biotech in mine to quiet it down. Absolutely loved that truck/motor, was an excellent ride.

I voted for the 0w40 as thats what i ran for 60k miles. Currently has HPL 5w30 premium plus in it

This 2006 Charger R/T went at least 277K miles on 5W-20, as of the latest update on it in November 2015. I wonder where that Charger is now, since the owner refreshed most of suspension back then...
