It actually works!

This product has been tested and reviewed by Porsche owners and oil experts on the Rennlist Porsche forum and is highly recommended.

BAD STUFF!

I purchased a couple of cans of this stuff to quiet a lifter that was not pumping up right away. It did work for a few weeks. The problem came when it was time to change the oil. I removed the plug from the oil pan and nothing came out. I check the oil level and it was full. The stuff had settled to the bottom of my oil pan. I played tee total getting the stuff out. I didn't use the second bottle. Also, the next time I changed the oil, the same thing happened. Still more had settled to the bottom. DON'T BUY THIS STUFF!

Liqui-Moly MoS2 Smooth2

I use this for every oil change in Lexus RX series. Engine runs smoother, and I am assured of extra engine protection. Great product.

Liqui Moly

This is one of the best product I’m using so far. After pouring in just one can, I can hear the difference in my engine after 20 second.

Looks like it works as described after 1 month use.

Seems to work well. it did a good job of quieting the lifters in my Ecotec 4 cyln .Their specific lifter additive didnt work as well. Seems to coat the parts as described. running it a month now.

Observed improvement on my truck F150.

I see 3 MPG increase in city and 5 MPG highway. With oil change... added this MoS2. No I am not racing... just easy cruising. With AC running at a soft feather spot of 68 mph on flat ground...no wind in a Coyote 5.0ltr V-8... Highway improved from 21 MPG to 24 MPG. Best achieved 27MPG without AC. Read full review

Very good but pricey

My riding lawnmower has a 17hp engine it used oil until I added a can of Liqui Moly at last oil change. It hasn't used any oil since. I highly recommend this.
