Liqui Moly is a German lubricants and additives brand founded in 1957, originally known for its molybdenum disulfide (MoS2) oil additives. The company is headquartered in Ulm, Germany, and manufactures all products domestically — the "Made in Germany" designation appears on every Liqui Moly product.
The brand is particularly popular in European vehicles (BMW, Mercedes, VW/Audi, Porsche) due to its extensive OEM approval coverage and European ACEA specifications. Liqui Moly's Molygen New Generation line features Molecular Friction Control (MFC) technology — a tungsten and molybdenum-based friction modifier that provides the product's distinctive fluorescent green color and UV-traceable leak detection capability.
Liqui Moly products are widely sold in the US at AutoZone, O'Reilly, and online, though the brand is more established in European markets. The company offers extensive lubricant and additive lines including engine flushes, fuel system cleaners, and specialty gear oils.
