    I've been using AMSOIL in my GMC Duramax for 15 years now and still have the original injectors. No problems with the engine and great mileage compared to most that I know. If you want to increase the reliability and longevity of your diesel truck or car, use this awesome product, seriously.

    All In One Does Its Job
    By  JIM,  a  Verified Buyer  from  Wisconsin  on  June 09, 2021
    Failed to verify captcha
    I've been using All In One in my diesel powered 2020 GMC Sierra pickup. When I started using it I gained about 4 MPG in fuel efficiency. The driving conditions before and after were the same, so I have to credit the improvement to All In One. Also, last winter I spent some time in the north woods with temps hovering about -25F. No jelling. The truck ran fine all winter. I don't know if I would have had problems without All In One, but I wasn't about to take the chance. I recommend to anyone running a diesel powered truck to routinely use All In One.
    Bottom Line
    Yes, I would recommend this to a friend.

    Use in my 2001 F350 7.3L Turbo dually crew cab. Had problem with injectors missing because of ULS fuel. Tried other products but this works better and faster than all the others. Made me a believer in Amsoil products.

    Just bought this new vehicle and manual suggested if you didn’t have access to trufuel you should use a product like this one. I researched the options and determined that Amsiol was the leader. Proof will be determined in the future. So far so good.

    Good product, didn't have any problems with my Diesel fuel gelling when we went into the single digits. I would definitely recommend. Don't like the shipping/handling prices though as they were more than the product itself..

    Yes, I would recommend this to a friend.
