    Maintenance
    By  ALLEN,  a  Verified Buyer  from  Canada  on  June 28, 2022
    Using in a brand new Gladiator Ecodiesel, adding at recommended dosage for maintenance. I can’t say I have noticed any difference in performance at this point as it is to early. I want to stay ahead of any issues. I may use a heavy clean dosage every fuel filter change out going forward as well.
    Bottom Line
    Yes, I would recommend this to a friend.

    Diesel Injector Clean + Cetane Boost
    By  Barney,  a  Verified Buyer  from  North Carolina  on  June 18, 2022
    Great Product! I have enjoyed a 1-3 mpg increase depending on highway or city driving. Smoking has decreased when "Rolling Coal" , engine starts better in colder weather. Running a HEUI fuel system in a 6.0 and using Amsoil heavy duty 15W-40 I will get as much mileage as possible out the fuel system.
    Bottom Line
    Yes, I would recommend this to a friend.
