Determining engine wear through UOAs is bunk information. You cannot track engine wear through any means except for measuring components before and after. You can have a cam lobe wearing down significantly without the UOA showing anything abnormal, it's happened to members of this very community.Respectfully, when data is analyzed without emotion and purely relying on static rules (viscosity in grade, Fe tracking with universal averages, TBN with plenty of reserve, etc) that show the engine is not at any additional risk compared to those who change at 5k, why should I spend the money and time and create extra waste?
Like I mentioned @wwillson… there’s absolutely no difference in his engine numbers with 20k (adjusted to a per 1k average) than guys changing at 3, 6, or 10k miles. Big sumps take a lot of oil. He’s saved 6x what a regimen with a 3k interval would have consumed. That would likely be well over $300 with conventional fluids, and was matched with roughly $100 of HPL. That’s real money in pocket with zero risk. The engine is cleaner, the parts are protected (the right balance of ZDDP, moly, and other AW additives), and the engine is not “suffering” because the oil is robust enough.
Without being political, one could say using HPL to its full life, whatever that is in each application, is not only “good for the planet”, it’s saving time and labor as well. Extending UOAs brings down the “carbon cost” of an ICE. HPL makes that cost-effective and SAFE because of its chemistry!![]()
People really overhype the relevance of cheap UOAs here. New oil itself is definitive cheap insurance. UOAs are not.
