Here's what I want to know. I know this is widely debated and has a lot to do with opinions and personal thoughts, BUT.
What kind of motor oil do you use in your 4.7's (or any of your Dodges, really)?
How often do you change your oil?
How do your trucks do with sludging?
AND Do you use any oil additives, ie, Marvel Mystery Oil, Seafoam motor treatment, etc...
There's so many options and I'm just getting really curious about this topic, I've done so much research...
