    To early to tell
    By  KEVIN,  a  Verified Buyer  on  June 03, 2022
    After hearing all the hype I decided to give amsoil a shot. I drive a 2015 F-350 6.7 powerstroke. I was a little disappointed To hear the dreaded typewriter tick as soon as I fired it up. I’ll run it for a while and change it again and see how it does on the second oil change. So Far I’m happy with it, the way it was shipped left a lot to be desired though. The box it came in had arrows saying this side up and both 2.5 gallon jugs were packaged upside down on their caps. They also forgot the free gift I was supposed to get which was like pulling teeth to get a replacement sent out.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great Oil
    By  DAVID,  a  Verified Buyer  on  May 30, 2022
    Just put this in my John Deere 1025R sub compact tractor. Sound better and runs smoother. When I first fired up the tractor after the oil change, i could not believe how much smoother the tractor run at idle and all the way up to full throttle. At this point in time, I'll never use another oil in this tractor. Great stuff.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great product
    By  CHARLES,  a  Verified Buyer  on  May 27, 2022
    I actually use this in a 07 Canyon and 14 Outback. The canyon burns 5w30 but not this. The outback burned a quart every 1000 miles of the 0w20, switched to 0w40 and burns a quart every 4000, I’ll try this in it and see. Next step will be 5w50. Outback is just a complete pos.
    Bottom Line
    Yes, I would recommend this to a friend.

    Reliably Refreshing
    By  CHARLES,  a  Verified Buyer  from  Texas  on  May 24, 2022
    In these truly challenging times it is a joy to find reliability in vendors. Many local vendors were out of oil for my diesel truck, I’m sure they are doing all they can to help their customers. A friend suggested Amsoil and I got a pleasant surprise. Amsoil seemingly has no logistical issues or they are managing them well and providing a great product for consumers. I highly recommend Amsoil.
    Bottom Line
    Yes, I would recommend this to a friend.

    Outstanding service and user interface
    By  Tony,  a  Verified Buyer  from  Houston, Tx  on  April 20, 2022
    Did a lot of research so that I could make sure that I would get the best oil for my ecodiesel. The detergent and additives package in Amsoil oil met and exceeded all my needs. The user interface on the website was fantastic, clearly and concisely helping me pick the right product for my truck and suggesting the filter that I would need. Shipping was super fast and arrived just as described and well packaged. Would definitely and have suggested to friends and co workers.
    Bottom Line
    Yes, I would recommend this to a friend.
