May 11, 2025

This is the first UOA of my recently purchased 1992 Crown victoria. The milage is low, the exterior and interior are in incredible shape for the age, and the vehicle has some mechanical issues, this is usually how I like to purchase my vehicles. The story from the seller is that the original owner parked it about 10 years ago when she was no longer able to drive, the vehicle sat inside a warehouse, and was recently revived after a long period of sitting, by way of a fuel pump and tank, possibly a wash, and apparently nothing else. I drove the vehicle home about an hour running on 7...

This filter looks pretty bad, but as far as I can tell, did not fail, no tears in the media that I could find, I think it did it's job under some pretty rough conditions. Happy to have it off the car though, it was not as stuck as I expected it to be

What went back on?

What's the date code on the dome? Has holes in the center tube, so probably a few years old.

Edit - saw the info in the linked UOA thread, so filter could be 15 years old. Please post the date code on the dome if it has one.

Would have been nice to see the media as a whole before it was cut up.

Definitely abused. What did you replace it with? The 820 is the most maligned Motorcraft on here but this one gets a Purple Heart.

If it didn't tear as the 820S is known to do because of wide pleating, then it survived. The oil looks close to a diesel oil c&p. In this case, (even if it did tear) the least of the issue(s) here. Hope your revival project works out.

A generic jobber filter from my work, I can't remember at the moment what it is. I will be cutting that one open as well though when it is changed after a short run

I didn't realize they had date codes! Unfortunately these pics are from a week ago, the filter is long gone.

Looks good and some cleaning happened. What oil went back in?

Thank You

That thing is nasty. After you do a couple changes to clean it up and want a quality wirebacked filter. Check out the fleet guard LF16002.

Bulk conventional 5w30 from my work

Thank you for the recommendation, it seems like it is getting harder and harder to find good oil filters for any application these days

That FL820S didn't tear because it's around 15 years old ... before M+H got hold of them.

Loaded to say the least as the UOA shows.
