    l'incontournable
    By  MICHAEL,  a  Verified Buyer  from  Québec Canada  on  March 02, 2025
    Permet de maintenir les injecteurs propres,. Avec ce traitement peu importe le diesel acheté, les performances sont au rendez-vous! Aide aussi à réduire la consommation d'urée en améliorant la combustion du diesel. Aide aussi à maintenir la lubrification de la pompe à injection. Au final tout est plus propre!!
    Bottom Line
    Yes, I would recommend this to a friend.

    Is it snake oil?
    By  ERICK,  a  Verified Buyer  from  Arizona  on  October 31, 2024
    I have been using howes, but after using the deisol treatment from Amsoil.I learned there is a difference.. this stuff cleans up your injector and piston crowns, valve faces..My old Ford runs great because of Amsoil products and over the top maintenance program..
    Bottom Line
    Yes, I would recommend this to a friend.

    Makes all the difference
    By  KEITH,  a  Verified Buyer  from  Rhode Island  on  October 27, 2024
    I have a 1997 Ford F350 crew cab, long bed turbo diesel. Without the cetane booster I can hear every tappet in the engine. With the booster, the mileage is better and the silence is golden. Well, as much as a 7.3ltr engine can be silent.
    Bottom Line
    Yes, I would recommend this to a friend.
