I suspect you guys have a little bit of a perception problem, nobody here criticizes anyone for not using HPL for one reason or another. "Darling", "wrath", "club", come off it, that's just something you're feeling rather than the majority of HPL users actually exhibiting this behaviour. I know you'll respond with that one post where one guy "proves me wrong", but the majority of us use it because we feel it's a very high quality product backed by very smart people and a team that cares for their end users. So yes we like the product and recommend it but that doesn't automatically we're slighting other brands.
I'm not against Amsoil (for example), I happen to be running that in my diffs. Just a choice I made based on availability of the product, the quality of it vs HPL (probably not much difference but I'm comfortable running either one), and the time I had to get the job done. But I'm very confident in that oil as well.
