Customer Ratings & Reviews

I had a 2014 Impala with 240,000 miles that was starting to use a lot of oil. I added this to the next oil change, ran it and did the change and I still used a little oil. I did it again at my next 10,000 mile change and I have not used any oil between changes since.I now have 270,000 miles. it did a great job of cleaning out the motor.

The Oil Wasn't that dirty before the change -- but looks like brand new inside after.

I ran this through our car to remove excess carbon buildup. It performed as advertised. Very good product that I definitely recommend.

My 2011 had very low oil pressure due to sludge. After using the AMSOIL engine flush my oil pressure is 15 to 20 psi higher. Right where it should be. Thank you

Used this product twice now, on a high mileage vehicle and it seems to idle smoother

I use Amsoil products in everything i own i used this flush in my 99 ram with the 5.9 gas engine.

I have tried other ways to clean the engine sand crankcase but using this product does what it says it does.

Had oil and transmission flushed with my last oil and transmission change . Can feel the difference in shifting as well as overall performance in. The 4.4L twin turbo.

It freed up my sticking lifter.

Works like a BAU5E !

I use the engine flush every 3 oil changes and it hasn’t disappointed me yet great product

This stuff really cleans the motor after an oil change…runs out like water!! Love this stuff

Good

This flush works wonders on my Cummins to help clear out some of the bad stuff left behind in the oil highly recommend it with at least every other oil change

I use this with every oil change, together with amsoil oil filters & Signature series motor oil. It really cleans out the oil varnish from inside the engines of all my cars. Oil remains cleaner this way. Genius product!

I like how this product helps clean out my oil crankcase prior to changing the oil. I use it before every oil change.

This product works very well. I add one each oil change not only to reap the benefits of what it has inside cleaning wise but also seems to get out alot of residual oil that otherwise wouldn’t come out. Every last drop but you must have a hot engine when adding it and draining it it works the best to melt away all the bad stuff

Perfect for my truck!!

Seems to work well Noticed much smoother engine sound after use of this flush. Followed by a oil and filter change. Used in a high mileage 2001 chevrolet impala.

Engine Transmission Flush is a great product. I use it every change, I limit it to 5 minutes run time. All of my engines are spotless.
