Maybe you could get some to clean up what the HPL leaves behind......J/K
I did the Auto-RX on my old Corolla with like 150k at the time iirc. It reduced the oil burning from like 1qt/1k to .5qt/1k by the end of the cleaning cycles. That car also countless GUNK brand Motor Flushes and an untold number of qts of mostly QS conventional iirc at 3k changes (and ZMAX/Slick 50 and others). I think I switched to a blend or full syn towards the end after the Auto-RX. It was probably one of the most talked about on here when I lurked for a long time before joining.
That was before (or at least I knew of) the BG EPR's, LM's and others. No qualms using EPR, LM, GUNK and others as the actual add right before a change. All my cars got BG EPR last year maybe 2 years ago.
Current learnings put me to the HPL EC30, and three of my cars are currently running it. The Pilot would get EC30 also but I want to do oil analysis again since I've been using for a lot more daily mileage. I didn't want any additives (like LM BioTech) in it to see what it shows. All of mine will get some HPL PCMO but probably only 1 qt after the EC30's are used up. I have enough of my oil stash that I can probably go 2 years before buying more. The HPL PCMO will be the add something better at getting and keeping clean on top of PP, PPE-L or M1. I'll probably get the 5W-30 version as 3/5 call for 5W-20/30 and have higher mileage. The other 2 call for 0W-20 but will some M1 0W-40 (Accord) and PP Euro L 5-30 in the pilot at next change after EC30 is used up.
Paralysis by Analysis is a definite thing especially after too much time at BITOG. Grab the dart board, cover with a BITOG BINGO paper and toss 1 dart then do that. You probably will not go wrong with any of the choices. If you don't like results, remove that one from next dart toss, lather, rinse, repeat.
