Customer Ratings & Reviews

The Amzoil flush on every oil change & have never had a problem with my car it's great.

Cleans out the gunk and gets the engine right!

your products are of very good quality. I hope you give discounts to your customers. )

It's a great product. I use it every 50,000 miles on all 3 of the above gear box's.

Use this every oil change and it works great!

My son bought a 2014 Mitsubishi Outlander Sport that had been sitting for a year. He got a good price on it but I told the dealer to change the oil and filter as it had a sticky lifter. I put a bottle of the flush in after it was warmed up and let it idle for 15 minutes. I drained it and put on a new filter along with XL 0-20 oil. When I started it the engine was totally quiet. I figured it was because the motor was still warm. I was surprised the next morning when I started it there was zero noise from the valve train, and it was in the 20's! Yep, this flush just straight up works!! Amsoil does it again

Awesome engine flush just idle for 10 minutes and then drain your oil that easy and you can see how dark and dirty the old oil drained is amazing

I have NOT used it yet. I have heard good things about this product and am excited to use it with my upcoming oil change in the truck. After that, I can follow up with a positive note for the product.

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.
