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.

I have used this flush 2 times. Once when I bought my car with 30k miles on it and once when it got to 100k. All the reviews are great on this product and I am sure it works as good as all the other AMSoil products.

Product did a good job loosening up some noisy lifters and got better oil flow going. Plan to use again before next oil change.

This was second time on my jeep oil change using this has increased my oil pressure. Plus at oil change the oil on dip stick is clear looking new. I have used in my other trucks does the same thing. Will keep using.

I use this flush before every oil change, and I mean every oil change.

Been using this engine flush for years and has always done an extremely good job my engines are always clean and healthy

This product does what it says it will do, Great product(S)

I USED ON 2001 CHEVY ASTRO - LOTS OF METAL SHAVING IN THE PAN - RUNS SO MUCH BETTER. EXCELANT PRODUCT WILL DIOFFENTLY MAKE THIS PART OF MY OIL CHANGES IN THE FUTURE - USED ON 2007 MERC. MARINER 2008 CHEVY HHR - ALL VEHICLES RUN BETTER AND NOTICED SLUDGE IN THE DRAIN PAN

An excellent engine flush. Works great

Very good

I’ve ran this on several vehicles every few oil changes and the engines are extremely clean and sludge free on the inside.

Perfect recommend

I use this occasionally in my daughters car. Her car uses a quart or a little more between factory recommended oil change intervals. What I found out is many car manufacturers started using softer material and not as tight a fit for the piston rings and this causes sludge to build up on the rings which causes oil consumption. I'm trying this to see if it helps.
