What are the credentials of these folks on this forum that their collective "wisdom" trumps the manufacturer recommendation such that these are the answers? Anecdotal at very best, these basement lab experiments with oils and "Uber" filters defy those which the factory specify. In a big-picture format, the hundreds of thousands of manufactured Hemi vehicles are very dependable and well engineered. The thin pie sliver of those whose owners seek problem solving unfortunately tend to fall into snake-oil remedies for their misfortune, and, when that fails, some scream "foul" and demand a recall or other factory recompense, which is iconoclastic in big corporate business models, who cater to share holders more intensely than consumers. One will never outrun planned obsolescence nor metallurgically designed long term fatigue failure engineered into everything from toasters to cars. I own an old fashioned coffee pot that percolates on my gas cooktop. When we had no power for 3 days here in Houston in February, engineering from my great grandparents' day enabled me to still warm up with fresh brewed coffee whilst my Keurig sat useless due to lack of electromotive force!! Several of my friends keep an old pre-computer era car for back up.
DOD (displacement on demand) change from v-8 to 4 cylinder is a very difficult and intricate answer to fulfill the gluttony for power demanded by the public for having their cake and eating it, too.
My wheezy 3.9L non overdrive truck is testament to "obsolescence" in todays speed and power greedy motorists who think 65 MPH is for chumps on Houston's highways where 80 MPH is just average. I feel like I'll be flattened whenever I drive it on these autobahns, so I no longer do, but it gets GREAT mileage.
I recommend (FWIW) that you put a genuine MOPAR filter on the engine, use the weight oil recommended, and go for the gusto. You will never fix an inherent engineering issue that plagues so few of the collective and is absent the majority of these engines.
As far as I'm concerned, only a different vehicle or replacement of the existing engine with a completely different unit will cure this problem once and for all, and that is a very capital intense remedy.
