This one run 4900 mi, one year with Magnatec 0w20 on 3.5L Honda. Super Tech Synthetic 10K mi (from box) and Bosch Prem. 3323 went back. First time using box oil, found with 12qt box best to have a saved 5qt jug to work with, which I did. This might be first louvered 7356 I've used, they were fine. That said, local Napa has discontinued Gold 40% off sale, so unless it comes back, could be last for a while. Bosch Prem. 3323 now better value for me.
