It very well could be an old filter, I have no maintenance history. I'm letting more oil drain from it before cutting the pleats off to look at the folds.

What did you replace it with?
There was a silicone ADV, it looked just fine. I tear holes in them to drain the oil out before opening so I don't make a mess. The new filter I put on was a Wix 51394XP.

Not any made in the past 4 years.
NAPA filters are Wix made,
Carquest (current ones) are Purolator made (except a few diesel and cartridge filters).
