    The best oil
    By  MACIEJ,  a  Verified Buyer  from  Wisconsin   on  December 18, 2025
    I used amsoil products for many years. Cars, motorcycles , small engines. I don’t have any problems with oil consumption, timing chain or anything else . I know it’s more expensive than other oils but I believe it’s worth it.
    Bottom Line
    Yes, I would recommend this to a friend.

    Easy way to get what you need
    By  JOHN,  a  Verified Buyer  from  New Jersey   on  December 14, 2025
    This is definitely the way to go when it’s oil change time. For those of us who still like to do it ourselves this make it easy to get exactly what you need. The kit includes everything you need and more. From the funnel and gloves to the reminder sticker it makes a good day into a great day.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  JEFF,  a  Verified Buyer  from  Iowa  on  December 12, 2025

    Go with the best
    By  ROBERT,  a  Verified Buyer  from  TN  on  December 08, 2025
    The extended drain interval makes it affordable. I would not do an extended drain interval with any other brand. Amsoil is the only lubricant my mechanic recommends because he has seen it all after 40 years of servicing everything mechanical. He is somewhat retired but still gives advice via a radio program. He warns against the inadequate lubrication car manufacturers are selling with lighter weight oil. He recommends Amsoil 0w30 to replace anything that is thinner. Works for me...
    Bottom Line
    Yes, I would recommend this to a friend.
