Reminds me of my 2002 Ram 4.7. After warranty I took over changing my oil and I noticed a oil sludge problem with that engine, and so did a lot of other people complaining about it.
Synthetic oil took care of that. It's made to take the heat. Great for lawn mowers !
You can make it dirty, but you can't wear it out. We made it, where I worked. I don't buy Walmart brand, if you know what I mean.
For my truck, filter only change, add a qt., and dump it once a year.
For now, stay in warranty and good standing.
To me, regular oil is minimal protection.
