    Cleaner
    By  TODD,  a  Verified Buyer  on  February 13, 2026
    I would say it is definitely doing something based on the color change in the oil. Checked oil with dipstick made note of color ran the flush through color was darker on the dipstick. When drained the oil it was definitely darker in color, so the flush is definitely loosening up some stuff in the engine.
    Bottom Line
    Yes, I would recommend this to a friend.

    By  Mike SC,  a  Verified Buyer  from  South Carolina   on  July 05, 2025
