This is a 5K run on Synergyn 3W30 in my wifes 2000 Mazda 626, 2.0L with 26K total miles on the engine. Also the oil was run 1 year. (11 months)
I did change oil and filter. I am running Red Line 5W20 and a Mazda Full Flow filter. Flat panel air cleaner from Napa (Wix) is holding up very nice in this engine.
