I ran this filter on my 2012 Silverado, Purolator L12222 about 8 months and 5k miles (oil is PP 5w-30). This truck did a lot of short tripping but it doesn't get too cold here in the Portland area. This is pretty severe service and the OLM ticks down twice as fast as if it was going on long trips. The OLM was at 12%. The oil was collected and will be analyzed soon. In the pictures it is kind of hard to see but the pleats adjacent to the metal seam there were tears, on both sides of the metal seam, both top and bottom for a total of 4 tears! Very disappointing to see 4 tears on one filter. I had to look really close to see the tears as there is still alot of oil on the pleats so the pictures didn't turn out so well. The last two pictures I tried to get the best shot of two tears on the same end of the filter, both adjacent to the metal seam.
