    Amsoil is God approved!
    By  Lee,  a  Verified Buyer  from  Grand Bay, AL  on  February 17, 2024
    One day about a year ago I watched a pro video about using an oil cooler. I have a 2006 CVO Fat Boy 103. Anyways, I went to the store for just after watching the video to buy something unrelated. As I was walking out of the store, I was thinking about the need for an oil cooler to keep engine temps down and the Holy Spirit reminded me that I was using synthetic motor oil. And I suddenly realized that I have all the protection I need using Amsoil. Now the Lord knows bikes inside an out. He's proven that to me several times, all the way from engine temps to front fork triple trees to a loose leaky valve stem.
    Bottom Line
    Yes, I would recommend this to a friend.

Doesn’t smoke and runs flawlessly👍 Used the 20-50w when in Maryland. Now using straight 60w for Florida weather…. All work and maintenance performed by me. Great oil. Nuff said 😎

    Will Use Nothing but Amsoil !
    By  DAN,  a  Verified Buyer  from  Central Florida  on  February 04, 2024
    Began using Amsoil 20W40 in my Indian Thunderstroke 116 (factory 116 with oil cooler) after trying a few other oils during the first 10K miles. By comparison, when using the OEM Indian oil, I experienced what I would call significant valve train "noise" at certain RPMs and also very noticeable transmission noise. I tried Castrol V-Twin full synthetic 20W50 during the summer here in Florida which quieted the valve train noise but after less than 1K miles I developed one sticky lifter that wouldn't pump up until the engine ran for a few minutes. At the suggestion of a friend, I started using Amsoil 20W40, formulated for Indian and Victory motorcycles. WOW, what a difference is all I can say. I immediately experienced a much quieter engine and transmission. The valve train noise is gone all together and the transmission is super quiet and shifts like butter. After only a few hundred miles with the Amsoil, my sticky lifter issue resolved itself completely and has not returned. I now have 17K on my bike and will use nothing but Amsoil. I highly recommend Amsoil 20W40 to all owners air cooled Thunderstroke engines, it's literally the best I've ever used.
    Bottom Line
    Yes, I would recommend this to a friend.
