This is easy to use and effective, will buy for every oil change.

Un excellent nettoyage de l'intérieur!

Very impressed how this product cleans the engine and allows the dirty fluid to quickly drain back to the pan for draining. Just follow the directions and again fill with new Signature series oil. Your engine will thank you with it's performance.

Sinds using this product all engines that had sludge ( minor ) clean out good

I use the stuff in my car and I immediately saw the difference in my engine it really helped it get cleaner and run smoother

Much more efficient then a standard oil change. Have not used in transmission.

Really frees up the engine gets better fuel mileage,runs cooler you can hardly here the engine running. Melvin shingar

Every time I changed the oil in my diesel, the oil would be black instantly. Even after I did an egr weight reduction procedure. I ran a bottle this as it said to, changed the oil and have about 1500km on the new oil. It’s still clean after switching to sig series max duty. I’m sold on this and AMSOIL.

I bought it but did not use it, my car has a lot of miles on it and was afraid that I would open a can of worms.

Used this on 220,000 mile Toyota. Engine oil was black as coal coming out. Engine is guider.

Seemed to really help clean the old oil out so I could start fresh with Amsoil.

I decided to flush out the Penzoil that I would use on my dodge charger 392, and added the AMSOIL signature series. Engine oil life since oil change and flush is at 80% and still looks golden.

Simply a complete clean up of the interior of the oil systeme.

I use this on every oil change not only have I seen how good it is, but it makes draining oil easy and fast. I’ve seen pieces of junk come out in the oil waterfall this creates. I wouldn’t not use it just for convenience.

Every 3 oil changes i run this in my oil for 15min before i drain it. I've had my oil pans off on both my vehicles since doing this and they look like new engines still

All Amsoil products are high quality and make a true good difference in the performance of our vehicles.

I have used this product numerous times and it does the job. Really cleans the engine with very little effort. I use this on every third oil change.

Used for an engine oil change. Followed the directions and drained after pouring into the oil and running the motor. Oil was way darker than normal when I drained it. Scoped oil pan and it was way cleaner than before.

I have used it 4 times in 4 different vehicles, I did noticed the oil coming out way darker than it was before using. does it work, Maybe but it certainly helps to break down sludge.

It’ works wonders
