Customer Ratings & Reviews

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.

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.
