PBR is probably still available somewhere; it has been reformulated though and I don’t think we’ve seen the replacement yet. But the biggest issue there (if you’re concerned about it) is that it was only ever a diesel-rated oil; it never carried any gasoline certs. I’s also more expensive than HPL EC or oil (PBR was $70+/gal, HPL is $70/6qts) and you’ll only likely ever find PBR at a Cummins service shop, when HPL will be at your door in 2 days.
I’m certainly not downplaying PBR; it was obviously a very powerful combination, but it’s way closer to most peoples’ ideas of what a boutique oil is: hard to get and REALLY expensive. HPL gives you all of the pluses and really only one of the minuses (it costs about double what WM shelf-stock runs). Toss in the fact that HPL is a board sponsor; has had several public open houses; gives members a 15% discount and $25 flat-rate shipping; and frequents the board with open, honest, and fair input on multiple topics… the winner becomes pretty clear (at least to me). @wwillson and @OVERKILL also have threads with pics on the incredible cleaning power of HPL’s AN/ester combination, and @RDY4WAR has done some deep-dives on the how’s and why’s of HPL performance.
