    Great for GDI engine
    By  ALEX,  a  Verified Buyer  from  Innisfail Alberta, Canada  on  March 31, 2021
    Amsoil oil filters have kept our 2 Hyundai engines in excellent shape. They are part of the Amsoil oil change that includes Signature 5W20 oil, upper cylinder treatment, and PI fuel treatment. Bought since new, the cars (Sonata 2013; Elantra 2014) perform very well and we plan to keep them as long as possible. Amsoil products and the Amsoil team are offering the best products. They are trustworthy and stand behind their products 100%.
    Bottom Line
    Yes, I would recommend this to a friend.

    Smoothed Out Idle
    By  NEIL,  a  Verified Buyer  from  Chicago   on  March 30, 2021
    Works wonders I tell you. My 2013 Toyota Highlander with 70k tends to idle rough and this fixes that issue. Seems to be doing it’s job at cleaning the cheap Costco gas that I use.
    Bottom Line

    Good product
    By  Sam,  a  Verified Buyer  from  Phoenix, Arizona  on  March 18, 2021
    For the first time I put in all 3 of my vehicles, 2013 Infiniti, 2011 Lexus RX350 & 2000 GMC Sierra. I only noticed a difference in the GMC, improved performance. Most likely because is has 287,000 miles on it. I'm sure it improved performance in all 3.
    Bottom Line
    Yes, I would recommend this to a friend.
