I’ve read that it’s better for the truck but…if you have a lot of miles on the truck or it is older it can dissolve a bunch of sludge and gum up the works.
Yep, be prepared to change out your fuel filters a few times until the system is cleaned out. Depending on the year model, B20 may not play nice with SCR equipped diesels. If memory serves, Chrysler specced B10 or B15 only.
