    Amsoil for 02 durmax
    By  KEVIN,  a  Verified Buyer  from  Alabama  on  October 19, 2021

    Describe the issue

    I used Amsoil years ago in my 02 durmax and saw instant fuel millage increase and then I switched to shell rotella t6 synthetic, thinking I would get the same performance. I could never get over 17mpg with rotella t6 so I switched back to Amsoil and again I saw an instant increase of 2mpg and now I get 19 unloaded. I also saw a significant increase pulling my 8,000 lbs camper. I recently pulled through Cherokee Nc and through the Smokey Mt. Pkwy into Gatlinburg Tn. I averaged 13.5 mpg ! I will never use anything else in my durmax again.
    Bottom Line
    Yes, I would recommend this to a friend.

    Love this oil
    By  PHIL,  a  Verified Buyer  from  Sacramento   on  October 09, 2021

    Describe the issue

    Before I started using this oil, my old 7.3 powerstroke would eat 3-4 quarts every 5k miles. Now with Amsoil, it barely eats a quart. This stuff is awesome.
    Bottom Line
    Yes, I would recommend this to a friend.
