Off of the 2005 LQ4 6.0 swapped Tahoe, about 4,561 miles on this interval. This is my last WIX 51522 from a 2021 master pack bought around the time we acquired the 2005 Suburban. Was changed in April and oil used was Mobil 1 FS European 0W-40. Filter looks great, no complaints here. If every WIX looked like this we would probably never talk about them.
Back in went more Mobil 1 FS Euro 0W-40 and my first ever PG made Microgard Select MSL51522.
