Nice product
Size: 5 Liter
Great oil my car burns a lot of oil even full synthetics. This oil still burns but the rate has noticeably reduced compared to the last stuff I used. A bit pricey but worth it

Experience Unmatched Performance with LIQUI MOLY MoS2 Antifriction SAE 10W-40!
Size: 5 Liter, Size: 5 Liter
recently used the LIQUI MOLY MoS2 Antifriction SAE 10W-40 part-synthetic engine oil, and I am thoroughly impressed with its performance. This product performed exactly as advertised. The engine oil provided excellent cold-start behavior, making starting the engine in low temperatures much smoother. Additionally, it maintained stable viscosity and remained resistant to aging, which is crucial for long-term engine health. One of the standout features is that it has no harmful effects on catalytic converters, which is a significant advantage for maintaining overall vehicle performance. Overall, the LIQUI MOLY MoS2 Antifriction engine oil exceeded my expectations and delivered on all its promises. I highly recommend it for anyone looking for reliable and high-quality engine oil.

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.
