I’ve typically used Wix or OEM but like Irish stated I believe they are all pretty close and regular maintenance is the key. I’ve also not abused a vehicle in a very long time. I laughed at the service advisor at the Harley one day when I told him that I service the bike myself. He said, you sure you don’t want a master mechanic doing that? I said sure, you know any? 😂 The reality is the young guy is the one doing the oil changes, the experienced guy is doing the big money jobs.
