I have a customer with an 2012 Honda Pilot. While adjusting the valves the front head was covered in sludge and oil and carbon residue. The VVTI system was not working properly due to this. I added a bottle of the Amsoil engine cleaner and ran the engine for 20 minutes. After removing the oil and changing the filter the DTC for number 5 cylinder went away. We are scheduled to repeat the process in 5K miles.

Great product for cleaning the VCTs, timing chain tensioners and oil channels. In combination with the signature series oil and the EAO17 filter I have 300,000 miles on my ecoboost and it still sounds like it did at 80,000

Great stuff!! Definitely gets the gunk out and ready for the good stuff!!

Good product, tested volkswagen passat execline 2015 and volkswagen jetta 2017 volsburg.

I turn wrenches for a living and have been wanting to check out Amsoil for some time now. I got a couple chevy trucks, 1 with a lifter ticking noise on cold start ever since i got it. I've done few engine flushes with liquimoly or autozone's house brand stuff and never rid it. I used Amsoil's Engine and Transmission Flush and Signature's Series oil and for the first time ever the ticking is completely gone!! they saved me the hassle of ripping off the heads and changing the lifters they made a believer out of me and I'll NEVER use anything else!!

We have always used this product in the used cars we’ve purchased. Why put clean oil in a dirty engine.

not the first time i use it will not be the last Great Product Thanks

I bought my 2013 EcoBoost with 70,000 miles on it. Been using the motorcraft full synthetic in it since purchase. In the last year and a half I put almost 35,000 mi on it and it definitely hasn't been running as smooth. I noticed my oil had been coming out dirtier than normal on the last two oil changes. So I decided to start using amsoil signature series. Before I switched over I drained the oil and threw on a new filter and filled it up with motorcraft full synthetic. After a week of driving on it I dumped a bottle of this flush in the oil and let it idle for 15 minutes. The oil I drained out looked as if I had put another 5,000-10k miles on it. Maybe even dirtier than previous oil changes. I decided to flush it again with some clean oil, and even then more debris and carbon came out(without the additive). I am now switched over to signature series amsoil, hoping that'll make a difference. Only Time Will tell. But as far as flushing out carbon and engine deposits. I can visually verify that this stuff does what it says it will do. Great stuff. Next month we do the transmission!

Flush my oil every oil change

Made my truck sound and feel like it did when it was new. Increased mileage by 2mpg, 6.7 Cummins, 152k miles.

Cleaned out a ton of crap from my Engine that had previously been leaking diesel fuel into the coolant system and coolant into my oil.

Get that sludge out! Helps to clean rings and restore compression.

The oil before I poured in the flush was clear but used... and after 15 minutes when I drained it was jet black .. and I found black flakes in the filter. The vehicle 2011 4runner is new to me 109,000 miles previous owner used mobile one

I used this before I did oil change and the extra stuff that gets loosened up and comes out is amazing. Great product.

Cleaned up the internals of my motor really good

cleans where I can't !!!

I don't know one way or the other how much it helped, my mechanic didn't didn't have an answer on how much it helped, but used it anyways as it was already purchased.

I use this flush every time I get a new car or am switching from a different oil brand to AMSOIL. Flush it out, change the oil and filter.

The answer is Yes! I know others that said it's not necessary, then I saw their valves and oil after their drain. Then I saw mine with the flush, I encourage everyone to do this with their engine to learn what I did.

Great product
