Unknown brand filter off a coworkers 05 Chevy Malibu with the 2.2 Ecotec. 130k miles on it.
I believe he said he ran this OCI some 7 or 8 thousand miles. Bulk conventional oil, only 2 quarts drained out when I changed it. I hope you can see the hole clean through the media in those pictures.
I've never seen one this bad in person, figured I would share it with you all. Lots of metallic sludge on his magnetic drain plug too. I worry for his engine.
I put in Mobil1 HM 5w30 and a silver K&N he brought with him, and I advised him to shorten his next OCI to 3k in an attempt to let that M1 clean the gunk out a bit.
