    Works
    By  triboanalyst,  a  Verified Buyer  from  Fort Garland, CO   on  January 14, 2023
    Have used Amsoil PI in past. First time in our new 2022 TRAIL BOSS LTD 2.7T 4 CYLINDER using E15 that is rated 86 octane average. It has 24000 miles on it and the PI is noticeably improving the burn. I am retired tribologist from a major OEM and did chem testing of fuels and lubricants for 45 years. Most additives don't work nor will they mix properly cold and via gravity or splash. Amsoil knocked this chemistry out of the park. Smoother idle, cleaner tail pipe and using crappy high altitude E15 fuels my MPG is up. Will and do use oil analysis from SYNTHETIC ADVANTAGE ISO CERTIFIED OIL ANALYSIS to confirm.
    Bottom Line
    Yes, I would recommend this to a friend.

    works well
    By  JOSH,  a  Verified Buyer  from  WI  on  January 01, 2023
    I only ran this stuff one time so I honestly can’t say if it does what it claims but it seemed to work pretty well. I would have to run it at least a few more times and average my mpg to say for sure one way or the other.
    Bottom Line
    Yes, I would recommend this to a friend.
