Among the variety of available engine oils the Liqui Moly is even superior to the more expensive oils with MoS2 from the house. I have a lot of cars and motorcycles both when driven even without this oil. The reduced friction in the engine could be felt, in particular, for example, with a 200 MB Automatic, who had a carburettor problem and therefore in the lower speed range jerked sharply. After changing to said oil before the carburettor has been repaired, the unpleasant jerkiness was significantly reduced. This prompted me to continue to consider adding separately available in my fleet, both the oil when. Another example was my Volvo 960 with 6-cylinder inline engine. On long distances the cruise control was switched on. The compensate the set speed by changing the injection quantity could without Liqui Moly clearly noted on a "bucking", despite automatic. This may be due to the automatic Volvo has bridged the hydraulic converter at a certain speed to save fuel. Liqui Moly with!) MOS 2 mitigated this effect noticeably. The difference is felt more: Rub your hands dry times against each other, and then with a cream or oil. You will notice: It "misses" and exactly this easygoing adjusts itself when driving, if the engine MOS scored 2. In addition, the fuel consumption is actually reduced. Of course, this is mainly due to the weight, or the mass of the car caused, but by the reduced friction in the engine nevertheless results in a saving, for example, in my Peugeot 605 diesel automatic approximately one liter per 100 Km reached. Importantly, studies the Faculty of Engineering University of Southern Germany: The metallic abrasion of all metals used in engine design has been dramatically reduced by the addition of MOS 2. Due to this reduction in wear naturally increases the service life of the unit. Incidentally molybdenum salts have been used in ancient times to lubricate the axes of the "covered wagon of the Great Migration." Since MOS 2 on the cylinder wall "adhere", also the cold start of the engine is much more gentle, because MOS 2 ensures "emergency lubrication", if the actual oil must be first distributed by the oil pump of the engine, which already takes some time. My conclusion: LM with MOS 2 is superior.
