This filter was on my 2001 Mustang Bullitt for ~2,400 miles right after I replaced the timing chains and intake manifold gaskets. It had 281,074 miles on it when I took the filter off and I used Valvoline Restore and Protect 5w30. Overall I think the filter looked great and was a good price as well. I also had a used oil analysis sent out but UPS immediately lost it at the store, Amsoil did send me a new one free of charge though.
Right after this oil change I went up to the Appalachian mountains, on tail of the dragon, Cherohala Skyway, Highlands Highway and Wayah Road. I worked the engine very hard with sustained RPMs above 4,500 and it did great and was a very fun trip. In total I put about 900 miles on the car in those 2 days.
The drain plug had a lot of metal on it, I am hoping it was just residual.

All of these filters I've ran so far the sticker does start to fall off, maybe from driving in rain and with where the filter sits on these engines.

The pleats look very nice and even as well as lots of them in their, especially compared to the FL-820S. Nice to see a metal crimp as well. I did not see any messy glue either.

The ADBV was super pliable and brand new still, granted this was low easy highway miles.

A decent bit of crud in the bottom, all those "bigger" pieces of metal are likely from the aluminum timing chain guide.

Some more metal and probably carbon or sludge deposits in the filter, the V&P should've dislodged some of this.

The filter element laid out.

Nice work. What ent on and in?
 
Onto 300,000 miles! :cool:
That's the goal! I am about to put the T56 back together which you see parts of in the background of the pictures. After my mountain road trip the TR3650 was having trouble getting into 2nd from a stand still, this has since gone away but I got the T56 for $650 and it was practically brand new inside which I was not expecting.
 
I'd like to have seen the bypass valve if it has one? Do you still have the parts?
If you are wondering about a ruffled leaf spring, I don't think this filter has one. The bypass valve is built in to the end cap like most Asian built PGI type filters.
 
Smallest particle filtered: 25 microns.
That's a nebulous specification since there is no efficiency percentage given with the 25u. They need a better technical writer for their website. It's probably 98.7% (Absolute efficiency) at 25u. It's going to catch particles smaller than 25u, just like any oil filter. Need an efficiency and particle size to define the actual performance.
