purolator classic L20195 ..i bought 4 for my JEEP liberty at WALLMART ..and after reading media tearing on the forum i decided to cut one open [brand new oil filter] and found a 1 inch tear where the media is glued together ..F11E 09B1 ....i won't even open the other 3 remaining oil filters ..very disappointed ..so much for the 97.5 efficiency ..i also noted that WALMART went back to the FRAM oil filters [now i know why]
