This STP XL was used for about 1k miles plus for another 20 hours of time running the car without being driven. The engine was started up twice a week and allowed to run for 30 minutes to warm up for a couple of months while the owner was doing some repairs and getting it roadworthy before putting insurance on it. The car was a 1982 mustang with a 302. Sadly there was some metal dust that came out of the oil in the filter. Did not find any metal dust in the oil itself. Metal was magnetic, but unsure of what it was. Plan on doing another oil change in 1k miles to see if the trend continues. Oil used was 10w30 Mobil super. I personally think this filter looks great! This ADBV was more pliable than the M1 I just cut open and it has even pleats! It looks like there is some attention paid to putting this filter. It used a coil spring rather than a leaf spring.
