Not to change subject….
I have the same oil filter currently with 45K miles.
I will take it to 60K….. maybe 80K.
Will eventually have Adam do autopsy and post the photos / results.
I cannot see any visible detritus in the pleats and dont doubt I could have come much longer than 20K.
Maybe sending it in for testing to see how it still performs?
I have a FRU with 5 years and 20K on my truck about ready to come off and am quite interested to see whats inside.
