    Power Boost
    By  Ed,  a  Verified Buyer  from  Washington   on  January 03, 2022
    Before using the Cetane Boost I liked the power my rig was producing pulling our 32 foot RV. After the 2nd fill-up using it I could really see the difference especially when pulling hills. I now always have an extra 1/2 gallon on hand.
    Bottom Line
