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.
