Looking back at the amsoil warning a couple things stick out, one it is for 2013 trucks and up, meaning the 10-48 rp size, which I'm not sure why anyone would use anyway?
Now, they also say temporary and it is fairly recent, so why temporary? Maybe the latest version, and there was one, has less flow or a different bypass. I had a low restriction filter and it was deadly to my truck, made it tick, and it was puro boss old style, so does it makes a difference? heck yeah it does, this rams are so finicky pay attention. All that was needed that time was a filter change and my truck no longer ticked. When you look at the why, you see the puro boss back then had a very few holes to let oil through. It had nothing to do with the media. I think most filters have went to cheese grater design, which appears to have zero issues with flow.
What once worked on older vehicles sometimes doesn't work on vehicles of today. It is an argument FOR low weight oil though, something for some people to consider.
old rp 20-820 versus old puro synthetic pre-boss.
