    The best
    By  JIM,  a  Verified Buyer  from  OH  on  March 20, 2023
    It all started when I used their double filter system when I used to drive for work 30 years ago. I was putting around 3k miles a month on my vehicle and looking to cut back on oil changes. I've been a fan ever since.
    Bottom Line
    Yes, I would recommend this to a friend.

    Everything i needed for 2019 5.9L oil change
    By  EVAN,  a  Verified Buyer  from  Cocoa, Fl  on  March 19, 2023
    Amsoil is the best. Hands down. I've been researching ways to prolong the lifespan of all my motors. Royal purple isn't even a close second. Do your own research. Amsoil is king. ..... anyways, I was needing quantity, viscosity and oil filter for 2019 dodge ram 1500 5.9l hemi. 7 quarts and a win filter for a little over a hundred bucks, not a bad deal. I change mine every 10k. Premium gas and amsoil and you should get 300k miles outta your engine. We'll see.
    Bottom Line
    Yes, I would recommend this to a friend.
