Oil filter Fram or AMSOIL

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.

Have used FRAM oil filters for 45 years, GMC trucks, VW, Honda, multiple Nissan trucks and never an issue all engines lasted till crashed or sold.

Also, I would just use Fram ultra synthetic for 5k mile oil changes. It has 99% efficiency at 20 micron, so it’s fine, and its 20k mile rating is obviously more than enough for 5k mile oil changes.

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 use fram filters, full synthetic 5w-20, for the last 150k miles. Total cost is like $25 at walmart. I am right at 210k miles now with oil changes EVERY 5k miles.

Runs good, but burns a quart by 5k miles.

I’ve worked on Subarus for over 20 years now and almost every blowed engine has a fram oil filter on it. Easily 75%

Using a cheap (fram) oil filter is a recipe for disaster, because those filters fail internally, and either go into bypass mode, or the internals of the filter grenade, and go directly into the crankshaft bearings.

Stay away from fram as the name is just ruined in many peoples eyes. I wouldn't buy something for good money with fram on it.

Fram Air filters: Their OEM filters are the absolutely best while the exact same filters with a "Fram" label are manufacturing rejects. Kinked pleats, misaligned bracing screen, holes in the gasket, missing glue, etc.

Fram Oil filters: Nope. Few pleats and not very strong. You can find lots of test and teardown videos. I've had past problems with the gasket swelling so badly that the filter has to be torched off.

FRAM filters are pretty dookie. They are known for coming apart and clogging oil systems. My RAM had FRAM filters for its 180k miles and its got little pieces of shit in the oil every time i check or change it.

I wouldnt bother with them.
