Customer Ratings & Reviews

I wouldnt reccomend due to flush generally being flush and brand doesnt really matter imo. But it works like it should and i have used it many many times just out of convenience when ordering my engine oil.

I tried this on my 2016 SCION iM and it did wonders by removing engine coking built up through the years. Along with Signature Series 0W-20 motor oil, my engine oil has never been cleaner. I will continue to use this engine flush for every oil change. Thanks to Eben for creating his Youtube channel & promoting his Amsoil products. He has really educated me on the value of Amsoil products.

Great product

Put into a 6.4 RAM hemi after replacing the cam, Lifters, and a new hellcat oil pump. Ran as directed. Amazing how dirty it became after running it. Drained and put in new Amsoil 0W-40. Runs so quiet and smooth.

Haven't used it yet.

Definitely saw darker and slightly more oil drained using this product for 10 minutes at idle.

This flush prior to changing from conventional to synthetic I would think. A fairly inexpensive way to clean out the crankcase, etc. to enable synthetic to have a fresh start.

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 +)

Great Refresh for the Engine, Speeds Up the Change! I used this before I put Amsoil in the first time, and it really made the oil black... and came out FAST! Now that we're changing once a year or 15K miles, might do this every time.

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!

Good

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.
