This Purolator synthetic was on a 2012 Didge Caliber with 4 cylinder engine. Had 2 runs of Quaker State Conventional 5w30 put in and on by me. Lots of miles my friend puts on. Put another load of Quaker State Conventional 5w30 and tough guard. The slices in ADBV I have no idea what caused them. Made May 8th, 2014 1st shift and Line "D"
