A Quaker State QS4386 ($2 from Menards) taken off of a 2005 Suzuki Aerio. Running QSUD 5w30. The 8300 mile OCI was not planned, it was not my car and lost track of the mileage. As said in the subject, filter was on for 7 months. Everything looks good as far as I could tell. The one negative was that the ADBV was stiff (to be expected). The filter still held oil, but I wouldn't push the cheap ADBV much farther.
