    I switched to Amsoil as I don't believe a motor oil (20W50) should be used as a primary drive lubricant. As I mentioned, personal preference, I want an oil specifically developed for clutch application, my first time using Amsoil and I have no idea how to tell if it serves the purpose. Bike shifts ok, will have to wait and see.
    Bottom Line

    Yes, I would recommend this to a friend.

    I installed this in my 2022 Road King Special, oil cooled M8 after the I put in the V-twin motor oil and I heard the ticking sound in the heads get lower. This primary fluid is thicker, more viscous than the Syn3 I had been using. I didn't notice the whirling sound in my primary until I put this in and it nearly disappeared. Between the 2 fluids, all I hear is exhaust at a stoplight now.
    Bottom Line
