Very informative and interesting. TY for posting.

FRAM is pure JUNK. They have bought many Cummins engines from rubber coming loose and plugging piston cooling nozzles.

Wix and NAPA Gold are ok but if you want top quality buy FleetGuard Stratapore or Donaldson. Donaldson makes the AMZ/OIL filters and are superior to the FleetGuard Stratapore.

Donaldson don't make filters, they sub them out.

I was hoping they would cut open the Mobil 1 filter I use :(

Wix for me and Rock auto has a deep discount going on right now.

I had a start up death rattle on a 2.7 Dodge engine. It was concerning if the vehicle sat overnight, and horrific if it sat a few days. I was DIYing the oil changes with dino and the orange cans at 5K intervals. A mechanic suggested I lose the Fram. I literally spent a few cents more for the commodity grade Purolator and the problem disappeared. The car was the infamous Intrepid and the motor had a horrible rep. for sludging. After the Fram mess, it continues in service, nineteen years later, with over 300K on it.

LUBERFINER the famous maker of the 3 micron bypass filter on so many tens of millions of big rigs in last sixty years is supposed to have one heck of a filter for cars now. Baldwin and Wix were the standard big rig filters then came Fleetgard.

Have not used a Fram filter since about 1985, used Purelator for many years. Once I got my Ram/Cummins I went with Fleetguard filters for the Ram, I noticed larger feed holes. I have never cut one open.

I Like the Fram Ultra XG8a in my LA318(not dissected in the linked video), but I'd like it more if it had the thread end bypass instead of the dome end bypass. I use an Fram Ultra XG16 on my Derale remote transmission filter mount on the cooler lines.

Wire backed synthetic media with good flow and some of the best efficiency numbers of any oil filter, like 99% at 20 microns IIRC, and rated for 15 or 20K miles, silicone Anti-drainback valve and under 10$ at wally world or online. Next favorite is the Mobil 1 M1-301 which has a very thick can, and thread end bypass silicone ADBV, but glass media, not wire backed and 13 to 14$.

I am not really fond of the combined antidrainback and bypass valve design on most Wix oil filters, seems like it could get kinked sideways, and stay partially in bypass with no antidrainback function.

I've not tried many others lately, the others I have tried were not made by the same factory/owners as they now are, so any opinions on those are no longer relevant.

Until something with better features for a lower price comes along, I will be sticking with the Fram Ultra, no matter who types the loudest, and will likely be using it for 2 oil change intervals, as I am doing with the currently installed one.

The FU XG16 on my ATF cooler lines might be able to be considered a lifetime filter. The in pan ATF filter is rated at somthing like 50% efficiency at 70 microns and are often referred to as 'rock catchers'.

Stick & brick Mexican bed collapsed. Sorry.
