This one run 5100 mi. in 15 months on Honda 2.4L engine with M1 0w20 AFE. Same oil and Bosch Premium 3323 went back. Run from early 12/2020 to beginning this month. Typical results ime, nothing unexpected. No excuses needed, thing is built like a tank. Obviously had I chosen could have run at least once more. I have one of these left, couldn't bring myself to use it yet. Saving it for posterity. lol I'll use it at some point.
