Oil filter AMSOIL or AC DELCO

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.

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

Ac Delco is the obvious choice for oil n fuel filter

I will never use any oil filter that is not OE/OEM.

AC Delco in the D-max.

It's an AC Delco PF2057 without a sticker on it. Completely fine filter overall.

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 got an ACdelco oil filter for a 07 classic GMC duramax and right before installing it I noticed the threads were stripped off and there were big chunks metal shavings clipped off inside it.
