        Hopefully Making the Difference
        By  ADAM,  a  Verified Buyer  from  Santa Fe, NM   on  January 24, 2026
        I keep it handy in door cubby of my 2019 Sprinter 4x4 and use it on every fourth fill. Because I trust Amsoil, I believe this to be a positive contribution to my vehicles performance; but there is nothing direct tangible about this.
        Bottom Line
        Yes, I would recommend this to a friend.

        Diesel boost
        By  Chip,  a  Verified Buyer  from  OR  on  October 25, 2025
        I really haven’t had a chance to really try it out because of work it I had originally purchased thinking that I was getting an injector cleaner. I will say everything that I’ve purchased from Amsoil has been above and beyond so I’m sure that this will be a good investment.
        Bottom Line
        Yes, I would recommend this to a friend.

        Crane boost
        By  PHIL,  a  Verified Buyer  from  Ontario   on  July 02, 2025
        I have used this fuel additive since I purchased my truck new. Fuel mileage and power is not the reason I use it. I use this additive to reduce re-gen of the DPF and it works great. In comparison to friends with the same motor (6.6 Duramax) I rarely have re-gen. Great product at a great price from a trusted manufacturer. Very happy with my results.
        Bottom Line
        Yes, I would recommend this to a friend.

        Great product, horrible bottle
        By  KEN,  a  Verified Buyer  from  NC  on  March 21, 2025
        I use a combination of Cetane Boost and Diesel Injector/Lubricator additive. They are great products (and needed with the ULSD fuel and CP4 pumps). Every fill up gets an appropriate addition of these Amsoil products. I see an improvement in mileage with the cetane boost. I have yet to have any internal pump or injector issues, so I hope the cleaner/lubricator is also working. However...EVERY time I pour from these jugs, the runback and leaks are horrendous. C'mon AMSOIL, do better. I would love to have your execs have to pour some of this stuff out to see how bad of a mess the jugs create.
        Bottom Line
        Yes, I would recommend this to a friend.

        It works!
        By  KIT,  a  Verified Buyer  from  WA  on  January 03, 2025
        I’ve used this for years in my 97 F350 7.3l power stroke. With a electrical fuel system, intercooler, upgraded injectors , this has provided the confidence the truck is getting the best considering how diesel fuel quality is going down.
        Bottom Line
        Yes, I would recommend this to a friend.
