Liqui Moly GmbH is a German company specializing in oils, lubricants and additives. Starting January 1, 2018, Liqui Moly is part of the Wrth Group which bought the remaining shares of the previous majority holder and CEO Ernst Prost. He now is the managing director of Liqui Moly, together with Gnter Hiermaier. Liqui Moly GmbH was founded in 1957 in Ulm on the river Danube. The patent for production of molybdenum disulfide formed the basis for the company. This additive based on liquified molybdenum disulfide (MoS2) was the companys first product and gave the company its name. Molybdenum sulfide, the basic ingredient of the Liqui Moly Oil additive, was discovered in the shops of the US Army in post-war Germany. These shops sold a can under the brand name Liqui Moly that contained the liquified form of the solid lubricant molybdenum sulfide (MoS2). When added to motor oil, this substance ensures emergency running characteristics in the event of a sudden loss of oil. Fighter pilots in World War One had already exploited this property, adding MoS2 to the motor oil in the aircraft engines. This enabled pilots to still land, even if the oil tank was hit.
