    Outstanding
    By  CHRISTOPHER,  a  Verified Buyer  on  August 06, 2025
    I have a 2018 Subaru Impreza. I was starting to get bad gas mileage around 145,000 miles. I switched over from using OEM oil and filter to using a wix xp filter with this oil and my gas mileage went back up significantly. Also, my engine sounds like it is idling more fluently and quietly again. I can’t say enough good about this product, I will be a life long AMSOIL customer.
    Bottom Line
    Yes, I would recommend this to a friend.

    Worst 1 gallon bottles in the industry.
    By  DAVID,  a  Verified Buyer  from  Colorado  on  August 01, 2025
    I love using their oil and the vehicles seem to like it too. BUT….the 1 gallon bottle are the absolute worst I have ever used. There is absolutely no way to get a smooth pour from the beginning. The oil splashes everywhere and oil is always dripping down the from of the bottle after pouring. PLEASE, PLEASE redesign your crappy bottles.
    Bottom Line
    Yes, I would recommend this to a friend.
