    Is it needed?
    By  WILLIAM,  a  Verified Buyer  from  California   on  September 13, 2021
    The answer is Yes! I know others that said it's not necessary, then I saw their valves and oil after their drain. Then I saw mine with the flush, I encourage everyone to do this with their engine to learn what I did.
    Bottom Line
    Yes, I would recommend this to a friend.

    Does as advertises
    By  Drake,  a  Verified Buyer  from  Michigan  on  September 03, 2021
    I used this on my !989 Ford Crown Victoria with the factory 302. I had somewhat recently changed the oil and it wasn't that dirty. When I changed over to Amsoil, I did the flush and there was a considerable darker color of oil that came out and was on the dipstick from when I started. Car actually seems to run a tad bit smoother and quieter as well.
    Bottom Line
    Yes, I would recommend this to a friend.

    Simply the best: Tested! Tried! & True!
    By  RANDALL,  a  Verified Buyer  from  Rusagonis, NB  on  August 23, 2021
    Swapping oils from conventional to Amsoil synthetic requires a product that can be relied on. The fact that Amsoil products are TESTED and not just manufactured for market value makes these products significantly superior to all the rest.
    Bottom Line
    Yes, I would recommend this to a friend.

    May have to try again
    By  GREG,  a  Verified Buyer  from  USA   on  August 01, 2021
    Used the flush as directed, with the hope that it would remove some debris out of the motor that kept clogging my oil pressure screen, after draining and refilling with amsoil and a new filter the problem went away for one day. And then returned. May try the flush again with the hope that it will work better this time
    Bottom Line
    No, I would not recommend this to a friend.

    Definitely cleans out build up.
    By  RAY,  a  Verified Buyer  from  Toledo Ohio   on  July 31, 2021
    Work just was advertised. Be sure to follow directions. The only thing to remember is that if you use it on a high mileage engine cleaning out the crud will probably do more harm than good. Seal will leak and bearings will rattle.
    Bottom Line
    No, I would not recommend this to a friend.
