    Amsoil is the best
    By  Mark,  a  Verified Buyer  from  SD  on  December 10, 2021

    Describe the issue

    Ordered my oil online thru Amsoil and had it send to a general delivery post office in Savannah. Was notified that it was delivered, but when I got to the PO, they couldn't find it. After nearly 10 days of wrangling, the PO found the package right where it was supposed to be. Received my oil the day before I was to leave. I really believe that the PO is about as screwed up as it can be.
    Bottom Line
    Yes, I would recommend this to a friend.
