Which average priced synthetic oil would you run to tackle varnish?

What is the evidence for ESP 5W-30 having AN? I might be misremembering what oil’s FTIR graph was posted, but I think it was this oil and I saw no sign of AN, which look like fingers in a certain part of the graph.

Your correct. I thought it was in a LSJR vid at HPL’s lab, but then remembered it was EP, Truck & SUV, and FS 0w40.

Does the current formulation of 0w30 ESP contain AN’s? I thought the 5w30 does while the 0w30 has esters for cleaning?

Nope, it's esters, I misremembered.

Yes. 0W-30 esters, 5W-30 AN’s.

Actually 5W-30 contains no ANs. I had the reference on this bookmarked, but unfortunately a mod decided to just delete the entire thread instead of just locking it. It was a great thread with a lot of evidence. Shame the mod just decided to rage quit on it. @dnewton3 @wwillson

here's a link to it (rip)

Jury still out on what the secret sauce is in M1 ESP 5W-30.

I took the time to remove the bickering, locked it, and put it back in PCMO.

What range of oxidation do AN or PAO or GRP III show in a VOA?
Click to expand...
Zero or near zero for PAO and AN, due to lack of oxygen atoms. I expect non-GTL Group III to have a very small concentration of oxygen containing molecules because the processing tends to get rid of the oxygen-containing molecules present in crude oil. I expect GTL to be similar to PAO in terms of lack of oxygen content. Whether dissolved oxygen gas in oils registers as oxidation in the test devices is an interesting question.
 
Yes I saw that after I replied. I was just reading in chronological order.

Edit: was replying to Glenda above. I guess it clipped the quoted messages even though I tried to reply.

My one year experiment with VRP is over and I have to say it was a smashing success. The varnish visible on the rocker arm through the oil fill is basically entirely removed. The filter loading has declined to something more typical of a regular oil change.

My odyssey is running fantastically. Having proven that VRP works and works amazingly well, I’m confident in its ability to clean to a degree never before seen in a wal-mart aisle kind of oil.

I’ll grab my “final” pics when I do the next OCI. VRP is a fantastic product whose ability to clean and protect is thoroughly well-documented at this point. If anyone remains skeptical of it, it’s because they have consciously chosen to ignore the large number of impressive UOAs, filter C&Ps, youtube video demonstrations, and other evidence showing this quite conclusively to be true.

The only reason I’m moving away from VRP for my van is because 1) I’m wanting to save my VRP for a couple other vehicles I maintain for friends that might need it more 2) I have a lot of non-VRP oil to use up, 3) having learned from my prior mistakes, I’m confident I can keep my van happy with non-VRP oils, and 4) I’m a relentless tinkerer and experimenter whose ADHD rarely lets him sit still when there’s new things to try.

VRP works by any measure of “work” for an engine oil that doesn’t include far extended OCIs. That’s beyond any reasonable doubt at this point for me. It’s not a 20k oil and not intended to be. If you want that, run a VRP regimen and switch to your preferred EP kind of oil like HPL once your filter loading dies off so you aren’t prematurely draining your EP oil. (That’s what I’m doing). HPL cleans well, but using it to clean when there’s a cheaper oil that cleans as well or better to me is a waste of money. Use the cheaper oil to clean, then switch to the HPL to enjoy an engine that stays clean AND goes much longer on an OCI.

This is a great data point. Thank you. Can you remind us what your oil change history was prior to VRP? OCI and oil used? I know you mentioned it elsewhere. I just cannot find it.
 
nice you mentioned Torco,they often are not as popular, but they produce a excellent engine oil among other products made.

Yes I'm not very familiar with them, but poking around online I found that page on ANs. I thought it was a pretty good explanation.
