Did a great job, will probably use the flush every 20,000 miles to clean everything up.

Absolutely works and does an incredible job removing all the gunk on the inside of your motor. If you buy a used car this is absolutely a must have and is to be used right away. Since the previous owner probably used junk oil you'll need this to remove it and give you a clean fresh start for the new amazing AMSOIL oils.

Ship fast and great products

Have used other stuff in the past. But, Amsoil flush makes my internal parts stay like new.

I used this product on my old 4runner and I could definitely see the sludge on the bottom of the oil bucket. The yota runs like a champ.

I've used this in my personal vehicles. A 2000 Ford Crown Victoria and 2006 Kawasaki Concours 1000. The interesting part about the motorcycle is it just had an oil change so it makes for a great side by side comparison. The best part was I used the same filter the previous owner used. What Amsoil's flush does that is different from what I've seen using other brands is how thin and watery the oil becomes. It breaks down the old oil down so much the chunks you see have probably been much larger and may have not broken off the areas they may have been stuck to. At my job I've switched almost the entire fleet of vehicles over to Amsoil and have used the flush in every vehicle. Anything from a Ford Escape with a 1.5l 3 cylinder Eco Boost to brand new Isuzu NPRs. There is nothing more important imho than using the Amsoil flush. Because my Crown Victoria had 190k miles at the time I did a follow up oil change just to clear out anything missed from the previous change and it really helped a lot. Engines do get build up from big oil companies cutting corners and even current mechanics look at data sheets and aren't fully understanding how Amsoil is cleaning the engines from "plaque" in a sense that is seen as higher than usual readings on charts. That is Amsoil cleaning the garbage that fake oils use and gets stuck in the engine. And that is what the flush is for. Do yourself the biggest favor you can to you and add this product to your top priority list when servicing your vehicle is coming up. You'll be glad you did.

Very impressive cleaning when changing engine oil in my LMM Duramax Helps my AMSOIL engine oil stay cleaner, longer ( 10,000km +)

Used on my 2003 Tahoe after flush oil pressure from 45psi up to 60psi. My engine alway has had great oil psi but flush increased it. I use amsoil signature oil tool

Haven’t noticed a difference yet. Going up against liquid moly engine flush

I use this in ALL of my vehicles, brand new, or older car! Excellent way to keep sludges and build up out of your engine!

First time using this product in the Toyota Tundra 5.7 Liter engine. It appears to have gained 1 mile per gallon since I used it.

ok

I enjoy thus product to help clean out the engine before a fresh Amsoil oil change.

I flush at every oil change. Honestly. Just try it. Truly the best brand on the planet.

Wonderful

One time use worked to eliminate a lot of sludge, after I physically cleaned most of the heaviest deposits. Good choice to start using Amsoil Synthetic Oils. Then the formula's will clean every oil change.

Makes good sense to clean up before changing oil.

Used on my car and gets better mileage

Does a very good job on cleaning internals of the engine

I use Amsoil Engine and Transmission flush on every vehicle I have, used or new. The latest vehicle I used this on was a 2016 Chevrolet Cruze LT. After warming the engine and letting the "flush" do its job, I removed the oil drain plug, and clumps of matter were literally dropping out of the oil pan. You never know how a used vehicle was maintained by previous owners prior to you purchasing it. You expect there may be some issues that you will encounter along the way, but your engine and transmission are the life of your vehicle. Using Amsoil engine and transmission flush along with Amsoil signature series motor oil gives me the best odds of maintaining the engine from this point forward and getting many years of service out of the vehicle.
