    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.
