After reviewing thousands of oil analysis results over the last 20+ years, I couldn’t possibly disagree with this statement any more. I don’t even know where to start so I’ll just leave it at that.
 
yall really think the shops..oil change places and half the crooked stealerships are using anything other than the cheapest crap they can dump in there..otherwise yer dreamers. lucky if they use spec oil even..maybe the dealer..but i doubt even that

Just because that may be common practice, doesn't mean that all oils are the same.

I recently bought 2 barrels of the prior high zinc Rotella and considering the chances are your truck will be primarily a daily driver just keep regular 15w40 and run added zinc.

If racing then 20w50 and change more frequently.

Agree with Rotella 15w40 with zinc for pretty much any build unless a dedicated competition truck. I would only use 20w50 if your build has the correct clearances and oiling/warm-up processes.
 
I’ve brought my Rotella to work and ran it through the lab against some of the stuff we blend. For a truck that gets driven take your pick between the top brands that are sold at Wal mart and choose an interval based on your driving style and conditions.

If you want to waste some time and really dive into this, go to Bob is the Oil Guy.com and send your oil off for analysis and spend 2 times as much on oil. Your truck probably won’t last any longer but you might feel better at night haha.
 
Application of the truck is the first order? What is it you are doing with the truck? Oil is not just oil. If you don’t have specs on the engine then weight of oil cannot really be determined. If you are not too worried about the costs, cenpeco racing oil with appropriate levels of fr3 gets my vote. All my 4+ digit builds get that. Otherwise as suggested parts store diesel oil with zinc additive and then a stabilizer to help aid with neutralizing acidic breakdown.
