    Black but don’t worry it is supposed to be. It works!
    Size: 1 Liter
    This stuff looks like used motor oil but don’t worry that is the molybdenum disulfide (MoS₂) which is black. This stuff in a small engine makes it smooth as silk. I used it all season in my leaf vacuum small engine. I could hear the difference. It was quieter and smoother.

    Works just like the Mercedessource guy said it would.
    Size: 5 Liter
    After viewing a Mercedessource video (trusted Mercedes repair advice Youtuber and blogger) on which oil he liked for higher mileage Mercedes he pointed this out Semi-synthetic 10w-40 out. Called it “muddy” oil. Said it possibly helped with small oil seal leaks and seemed to slow oil loss in higer miles Mercedes. Also made the engines run more quietly. So I have been using in my wife’s high mileage Mercedes (185,000miles W211 2004 E500 4matic) which we baby and I work on. A true very high compression super car, everything he said at Mercedessource has turned out to be accurate. No more leaks. Quiet lifters. Cooler running. Wow. I had been using Mobil 1 full synthetic 0W-40 European Car Formula exclusively but tried this for the seal protection. Works great and no, it is not Mercedes spec but I will see when the harsh Utah winter hits. May switch to the Liqui-Moly 5W-40 Leichtlauf full synthetic (which does meet Mercedes 722.9 oil spec) for winter (I change the oil every 6 months regardless). Thanks for reading.
