    Only oil for a pan head .
    By  Lionel,  a  Verified Buyer  on  October 15, 2019
    I operate my 1961 harley Davinsion duo glide also known as a pan head , I use it in the motor and four speed transmission ,having driven it eight thousand miles and only adding three quarts to top it up as the primary and secondary chains are lubricated by the engine oil and then allowed to drip out .I keep an eye on the quality of the oil by checking it with my lubricheck oil tester .

    Top notch
    By  Steve,  a  Verified Buyer  on  October 03, 2019
    Have used this oil consistently on my 2003 Vstar with 50000 miles on it. Best you can do for a motor is use the best oil you can afford and change it regularly. Amsoil fits the bill. Thanks for a fine product
