As we now have a 19 Laramie Night Edition alone with the 06 5.9L Cummins.
I’m curious what everyone is using for engine oil. 5w40, 10w30?
Also what brands does everyone like?
I live in Texas so below 0 is not all the time in the north part of the state but it does hit it with the wind chill.
Valvoline, Amsoil, etc.
