It would depend on the particle size and geometry. As you state, “somewhat” is probably accurate.
I'm babying this truck, and I don't intend to ever sell it. Lifter failure is undesirable, however, I'm trying to be cautious. If that happens, I hope that the magnets catch as much debris as possible. I was contemplating attaching neodymium magnets to the steel oil pan as well. It may or may not be a good idea. Otherwise, I had all the usual problems that trucks of this vintage come with, like broken exhaust manifold bolts leaking valve cover, both on the passenger side. I replaced the manifold, gasket, and bolts with brand new OEM parts, and the valve cover seal. The exhaust manifold is fine, the valve cover is now leaking from a different place. I am replacing the entire thing this time around with a brand new cover, gasket, and bolts with rubber grommets.
Oxidation numbers of virgin Redline oil is high due to their base oils. Look on the numbers in the voa postings. Redline oil can give for some reasons different uoa numbers that other oils.
RedLine has a higher ester content than other oils. Motor oils that contain higher amounts of esters will show higher oxidation numbers even in VOAs. BTW, that's not something Blackstone measures. POE should have good oxidative stability though. I've read many theories over the years, however, looking at the UOA in this thread, I don't see anything unusual when it comes to wear metals in his UOA when compared to other UOAs I've seen for the 5.7 HEMI. To get RedLine 5W-X to thicken like that, you have to run the oil repeatedly at around 250F or higher, at least that's what I've seen happen in HEMIs.
From RedLine's own website:
Q: HOW OFTEN SHOULD I CHANGE MY RED LINE OIL?It depends on how you drive. If you do a lot of city driving or low speed/low frequency driving, we recommend oil changes at 7500 miles. Vehicles that see more highway driving can go a maximum of 15,000 to 18,000 miles with an oil filter change in between. Modern filter technology and the latest, clean-burning fuels have reduced the solids that contaminate oil, so frequent filter changes aren't usually necessary.
What's your opinion? The cam and lifter problem is either quality control or oiling system design problems. Roller lifter flaw is the bearings.
The thousands and thousands of pages of endless discussions about lifters' issues and oiling systems is ridiculous, however, it comes up every time people talk about the HEMI. Even YouTubers like Uncle Tony and ReIgnited try to cash in on sensationalism to get more views. Personally, I'm no longer interested in the latest speculation as to why some HEMIs experienced lifter and/or cam failure. The HEMI is not a lawnmower engine that works with splash lubrication, nor will it run better if you install all non-MDS lifters and then enable MDS in the computer - yes, I saw this on ReIgnited on YouTube.
I believe that it's a supplier side issue affecting a small number of engines. The problem is exacerbated by the wonderful combination of high heat and thin 0/5W-20 oils. When you tow while going up a mountain, like the "Ike Gantlet" in Colorado (shown on TFL on YT), and you see oil temperatures upward 285F and you're running 5W-20, well you should know better. Don't expect a light duty truck to perform like a 2500/3500. It won't.
