    Smoothing Out My Thunderstroke Engine
    By  DOUG,  a  Verified Buyer  from  Port Charlotte  on  April 25, 2025
    I was curious what switching from Indians 20w-40 semi-syn oil to Amsoil 20w-40 full syn might do to the operation of my Indian Chieftain 116 Thunderstrike engine. From the first ride, I was surprised that the engine ran with less vibration than before. It was also about 50% easier to find neutral (the worst of any bike I have ever owned in 50 years of riding) than it used to be. Cheaper than Indian's oil too. Try it. You will not regret it.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great oil
    By  KENNETH,  a  Verified Buyer  on  April 23, 2025
    I have been using this oil in my Victory Cross Country for 10 years with no issues. It keeps the engine cooler. No issues with the clutch at all. Great product. Only issue I have is with the price why do you charge shipping?
    Bottom Line
    Yes, I would recommend this to a friend.

    Great Product
    By  DSW,  a  Verified Buyer  on  April 22, 2025
    I recently switched to Amsoil from another synthetic brand for my 2022 Harley Ultra. So far very pleased with this product and find the engine temp is slightly lower and the engine noise is noticeably less. It's great to be able to order everything together (oil, filter and o ring). I also really like how easy it is to get Amsoil and get delivery right to more door typically in a day.
    Bottom Line
    Yes, I would recommend this to a friend.

    Good Stuff!
    By  DEBRA,  a  Verified Buyer  from  North Port, FL  on  April 21, 2025
    This is the first time I used Amsoil on my 2012 sporster 1200 and I believe it made my cycle happy! It made a sound like it was drinking it! Then I changed the primary oil and it shifted better. Put the gas treatment in and that was the cherry on top!
    Bottom Line
    Yes, I would recommend this to a friend.
