    Best cleaner on TGDI Ford Ranger 2020
    By  PATRICK,  a  Verified Buyer  from  Ca  on  December 06, 2020
    Tried other products including Redline . Noticed very little difference with the Redline product and vehicle started idling a bit erratic at 23000 or so. Put in PI and after about 100 miles all erratic issues resolved . Great product . Buying more

    Never use anything else
    By  CHERYL,  a  Verified Buyer  from  Utah  on  December 03, 2020

    Why not?
    By  RICHARD,  a  Verified Buyer  from  Sacramento, CA  on  November 26, 2020
    makes sense to use this in your gasoline engine... the crap fuel being sold is damaging to our engines. I am convinced Amsoil knows exactly what they are doing. I am a loyal customer and user of their products.
    Bottom Line
    Yes, I would recommend this to a friend.
