    Amsoil Signature Series 5W-30 Synthetic Motor Oil
    By  Cutiepie,  a  Verified Buyer  on  February 13, 2023
    I purchased this product because my hubby, who is now in heaven, used it. He believed in using synthetic oil for our vehicles because synthetic oil is better for the engine. I haven't used the new shipment yet, but I will when it is time to change the oil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Quiet operation and preforms well!
    By  MIKE,  a  Verified Buyer  from  Suisun City Ca  on  February 12, 2023
    We own a 2008 Corolla ,which requires 5w-30. We were running a leading Synthetic oil which rattled on start up ,until the lifters pumped up. As soon as we changed to AMSOIL all the cold start rattle stopped. I have a history of AMSOIL in all my cars and this has always been my oil of choice!
    Bottom Line
    Yes, I would recommend this to a friend.

    The. Best.
    By  CHRISTOPHER,  a  Verified Buyer  from  Calofornia  on  February 12, 2023
    Doesn’t matter what ICE you have, Amsoil is the best. Contains more anti wear additive package, TBN, film strength, and resistance to heat induced breakdown of any other oil. Oh also cold flow stability, no other oil of the same weight flows as well as Amsoil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Backed by science
    By  CHRISTOPHER,  a  Verified Buyer  from  California  on  February 12, 2023
    Independent testing and laboratory independent testing both confirm by a measurable margin amsoil is in fact the best oil on the market. It is not snake oil it’s truly the best at film strength, anti-wear additive package, total base and TBN anti-acidification properties are superior than any other brand yes including the purple bottle.
    Bottom Line
    Yes, I would recommend this to a friend.

    5w-30 Signature Series motor oil
    By  CHUCK,  a  Verified Buyer  from  Ragland Alabama  on  February 09, 2023
    The 5W-30 signature series is a great oil for my HVAC work van. Chevys need all the help they can get to keep the lifters from ticking. The AMSOIL does the trick.

    New Bronco
    By  TIM,  a  Verified Buyer  from  Central Florida.  on  February 08, 2023
    After waiting two years to take delivery of this new Bronco . I could only seriously consider using the best synthetic oil on the market. With wear and heat protection needed for the twin turbo motor is a must; especially in central Florida's warm and humid climate.
    Bottom Line
    Yes, I would recommend this to a friend.

    It’s oil
    By  EDWARD,  a  Verified Buyer  from  Newport News   on  February 01, 2023
    Good oil good service. Would be nice if you just included funnels with each oil purchase. For what people pay for oil, it would be a great item to just give to customers. They are almost always necessary
    Bottom Line
    Yes, I would recommend this to a friend.
