Customer Ratings & Reviews

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.

This will be my time using this product but it looks promising. Keeping an engine clean is always a good idea.

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.

Keeps my internal engine clean

I have used the Amsoil Flush on most of my cars and on my adult children's cars as well as my grandson's cars. We all drive used cars and when a replacement car enters the family stables they get a flush before converting to Amsoil if they are of a higher mileage vehicle. On my Volvo wagon that I bought with 113,000 miles, I had one VVT assembly replaced by the previous owner prior to the sale. I did three flushes as I was concerned about it's service history. I really liked the car and negotiated the price based on buyers inspection and decided I'd do a few flushes and short drain intervals in hopes of improving the health of the engine. Six years later I have had no problems and the oil filter media looks great.

Great product

I was having a oil pressure light come in at low idle. Dealership said it was likely due to a sludge build up. After being told by a dealership it would take $1200 to treat with there product, I did my homework and tried AMSOIL Engine Flush. 15 minutes idle with the product as directed, and I have have no issues in months.

My 2010 Denali with the 6.2 L engine had the infamous tapping (sticking lifter) noise. The oil was new when I received the Amsoil engine and trans flush. I put it in and the new oil came out the colour of tar. After new oil and filter the tapping was a lot less. Ran it for 10,000 kil. and did a (2)second flush and again it came out black. Did the oil/filter change started it up and NO tapping. Great result I didn't expect.

I used it for 3 oil changes on my VW and Toyota. It makes life much easier by loosening up thick deposits. The oil drains out so much faster and cleaner with the added benefit of keeping the engine clean. Don't skimp out of oil, transmission fluid, and coolant.

Amazing how much crap this stuff cleans out of your engine!!
