This filter was off a 2014 "old body style" Impala at our work. One of the guys accidentally put 6 gallons of Sunoco auto diesel in. Got almost back to shop after diluting rest of it with gas. Dropped tank and replaced fuel pump and changed out spark plugs and fresh load of ECO POWER 5w30 by safety Kleen and a champ labs PH 500 and good to go. I drove it for about a week and put some serious miles on it then changed oil again. Looks good considering and it reeked bad of diesel. I am gonna guess this is NOT a CQ "BLUE" since it doesn't have wore backed media, but does have a silicon ADBV. The damage is from me also so I apologize up front.
