I was skeptical, but I started using it and their best filter in my '98 Durango 5.9 (gas). I ran it for the full 25 K(+) and sent an oil sample out to a 3rd party "Analysts, Inc." for a full analysis - including spectrographic. Basically, their recommendation was that the oil showed minimal contamination, acceptable viscosity, and was still OK for continued use and to re-sample at next interval.

I use amsoil, pricy but the filter is what's really worth it and before I changed my valve seals I burnt quite a bit less, it went from a quart every 800-1k miles to a quarter quart in that same time frame.
Just had an amsoil filter fail at the gasket. The inner diameter was too small causing a crease in the gasket that leaked after 4 months use. Nearly ran me dry.
I recently switched to Amsoil using a Mann filter. It runs great.
I have used the Amsoil Premium diesel oil and filters for the last decade, changing them once a year, and my truck is doing just fine.
I use amsoil oil and amsoil filter
I have experience with the long drain intervals from Amsoil. I have 2 dodge vehicles with 3.6L engines both at around 130,000 km and I use the signature series 5w20 with Amsoil filter and I go about 18,000 km before I change the oil.
I do this every time. I buy my amsoil and filter and the dealer only charges me labor
I'm running the amsoil remote filter, it will help with your oil quality.
I installed an AMSoil satellite oil filter. I change it out every 15k and change my oil and primary oil filter at 30k.
