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.

This stuff works great!

Used the flush as recommended, switched over to Amsoil oil

Have been using this on my Ford F250 after each oil change. I do notice that it cleans out the old oil and doesn't appear to harsh on the engine. I use 5W-40 Amsoil diesel oil and filter and it makes my F250 run like new, quieter and smoother.

Great product to use...really clean up deposits.

Now even though my car is new, (2020 Honda Civic Type R) at 3000 miles I went ahead and changed out the oil with Amsoil's 0W-20. Before doing this I did something that I'm not sure I was suppose to do and that was to flush out the engine before adding in the new oil. So far things have been great. Time will tell if I made a mistake in doing this, but I just wanted to keep the engine as clean and maintained as possible.

Ran this stuff through a 05 Civic with 225k miles on it. Drained oil pan and oil came out with small sludge clumps and very dark. Not used oil dark. You could tell it had cleaned the internal engine components. Quieted the valve lifters also. Worked as advertised!

Great product, works well especially with the extended drain intervals.

Before I put it in . I Took off the oil cap filler you could really see How brown it was from the oil stains after flush it was very shiny!

Amsoil Engine and Transmission Flush is a great way to start you oil change process! Used it in my 2018 5.7 RAM last oil change and got noticeably higher oil pressure. My engine also seemed much quieter!

For engine flush is the best over all

I've never used this in my transmission but I've used this to prep two engines for Amsoil Signature Series. It is great for cleaning out pockets of sludge in the engine! The oil that came from my oil change in the 1987 Ford 300 was very thick and dark. I have maintained that truck engine since it was my daily driver for six to seven years.

BMW S1000XR. 52k on the bike, runs better than new. I expect to post someday with an extreme mileage score on original motor.

This gets out all the old and makes more room for the new. The only oil products I use!

Use this Before oil changed. You can definitely see the loose sludge particles come out after using it

Are you still in my voice Chevy Cruze for the oil change. And can actually see sludge particles come out when draining the engine oil after use.

Great Product

If you want to have the full protection amsoil can provide you need to run this through your vehicle first. It makes a huge difference, and will allow your vehicle to get the best out of having amsoil in it. Don't do this first ypu are robbing your vehicle of the protection amsoil can give it.

I used this product in a used municipal vehicle that I purchased at auction. Amsoil flush removed the varnish and build up in the top end of the engine and also solved the lifter ticking noise at start up. Definitely a must when changing oil in a used vehicle with no service records.

Use it every time I change oil in my 2004 Chevy Silverado 5.3. Works great.
