LiquiMoly 3721 Engine Oil Additive

I trust ceratec brand for keeping my metal parts inside my engine area lubricated. From my understanding, it bonds to the metal so it doesn't dry out and you don't want to start an engine with dry metal because most of the oil falls down to the oil pan. It came in a sealed plastic wrapped package which I like so it's not tampered with.

Excellent product. I highly recommend it

Works really well at quieting down a noisy engine. Great value

Recommended product. Arrived well packaged.

This is good stuff! My engine got a little bit more quiet, and noticeably smoother, and I got a little better gas mileage on highway trips about 2 1/4 miles per gallon more. Just so you know, it’s in a 2006 Mercedes-Benz C230 sport with 206,000 miles. I had changed the oil about 2500 miles ago with liquid Moly 0 W-40, and I just poured it in. No lie you can actually hear it circulate and quiet down the engine and it’s really cool to hear.
