This filter was on the Monte Carlo for a little over 8 months and exactly 3,967 miles. Nothing too exciting to report, seemed to hold up nicely for a budget filter. The ADBV, although Nitrile, held up very well. I've had the filter sitting off the car upside since the oil was changed about 3 weeks ago, when I cracked the shell, oil still poured out and as you can see, the valve is still very pliable. Not bad for a closeout filter from Rock Auto.
