    Best Harley oil
    By  MIKE,  a  Verified Buyer  from  Your moms house   on  June 02, 2022
    This is the best Harley oil money can buy. I’ve put this oil in multiple bikes and had the engine run noticeably quieter. Also because Harley’s are already some what sensitive to warming up before you ride, the straight weight doesn’t have much down side in 55 degree and above weather.
    Bottom Line
    Yes, I would recommend this to a friend.
