Great stuff!!

Great product, flushed out all the oil. My oil pressure stayed at 40.

On my new to me car with 137k on it threw the engine and transmission cleaner in her and after 15 minutes drained and replaced the filter. Added four and a half quarts of 0w20 Amsoil OE grade oil and she runs smooth but she is noticeably quiter

A very good product. I recommend if you were changing over to Amsoil, used this product first to flush anything out of your engine. You will be amazed at what comes out of your oil pan

Recommend using this product for oil changes if you want to get any possible gunk that might of built up over time. i use it every oil change so there is less contamination when i put in the new oil.

I love it. Not much to say. It works good, it's affordable, and it's easy to use.

Amsoil flush clean your engine so the oil can do it's job better.

Great product!

Recently purchased a 95 Volvo 850 for my son with only 178,000km. (110,000mi.) We’ve been going through all the mechanical and decided to do an engine flush. The car had been running great but had a slight lifter tick at idle which I thought was pretty normal for a car of this age. While idling through the flush time, the lifter noise stopped and then would come back. At 15min the lifter tick was almost gone so we ran the engine for another 5min and the ticking had stopped! I was impressed! Drained out the now dirty oil again and did another complete oil change and the engine is smooth and quiet. Never have I seen an additive work so quickly and with such visible (audible) results!

Great product works always

Recently ran this through a neglected Polaris UTV and changed the oil. A week later I changed a valve cover gasket and everything inside looked like brand new. Wasn’t sure how effective this would be, but now I’m sold on it!

Good product

To just dump the old fluid is not enough, just get as much of the old fluid and impurities out as possible. Using the flush as per the instructions is the best method.

Don’t yet know.

Used it on the engine I noticed the the engine ran slightly quieter then normal

I have used it before on all my pickups I’ve owned in the past, before running Amsoil in them. Works great.

Definitely worth using, seen this stuff used on YouTube. So I had to try it. I was surprised how good it worked. Will be using it on every oil change.

It was mind blowing to see all the gunk come out of the filter. Hell yeah!

Definitely a must use product before oil changes to keep it clean. I noticed a rise in oil pressure after a few uses in my 2013 sierra that has over 167k miles on it. Trucks runs smoother as well as quieter.

My 2017 GMC Duramax has always had synthetic oil and always changed before it was required to do so. The flush was used as directed by Amsoil. When I drained the oil a big sludge of something came out and plopped in my change pan, I was very surprised. I have always used the best filters, ACdelco, Amsoil, or Mobile1. I seems to be a little quieter, l have nothing negative to say, it apparently removed something from what I thought would be a clean engine. By the way, for $10 bucks ever six months you can get preferred pricing on all their products. Meaning you can get the best oil on the market for less then you would pay at ChinaMart.
