How old are these ph3593a filters and do you want to see them cut open?

[oil pan 4]

Ones got 485hrs it running a Kubota 3cyl 900cc diesel. Don't know it's that's all on the same oil change.
When were they selling these?
Just within the last few years or longer?

Assuming there's no date stamp... not certain. Definitely want to see them cut though. Do they have silicon ADBV?

The adbv is black and the holes are small so I can't really tell.
A sloppy stamp on the side of the filter that could be a date code says a60671.

That would be the 67th day of 2016.

See the sticky thread at the top of this forum on how to read date codes.

Thanks, Good info & @ZeeOSix has the date. I know they've had silicon ADBV on the PH for a few years now.

Stop teasing us. Cut them apart or mail them to me and I’ll cut them open and post them

I got to let it drip out for a day or 2.

That would be the 67th day of 2016.

Its probably been on there since some time in 2016 then.
Not ran for at least the last 2 to 4 years.
I didn't know that was a date code. Never had a need to look up a filter date code before.

Remarkably clean for 485hrs on a diesel.
I chooed it open Friday morning and took the pic when I posted this.
Been rolled up in a soaker pad since I cut it open.
Looks a lot cleaner than the 1,344hr filter.
The 1,344hr filter was rolled up in soaker pads for 2 weeks and was still jet black.

That ain’t many hours run time on a diesel. Try 8-10,000 hours like dads company did on off road Mack R model rigs

The 1,344hr filter I cut open from a 15L diesel was quite dirty. The manual said to change the oil and oil filter at 300hr for normal operating conditions and 500hr with ULSD fuel and ideal opening conditions. Pretty sure we were doing "normal operating conditions".
