MOTOR OIL © iStock Low-viscosity 0W multigrade motor oils from MOTOREX reduce friction loss and help make engines increasingly efficient. LOW-VISCOSITY MOTOR OILS EFFICIENCY SHAPES THE FUTURE The stage has been set: Internal combustion engines must become cleaner and ever more efficient. With the new 0W generation of extremely low-viscosity, low-volatility motor oils, MOTOREX offers a key contribution to improving efficiency. Optimization of the internal combustion engine is in full gear. The main focus is on the combustion chamber. With increasing compactness, the direct fuel injection commonly associated with diesel engines is now also favored for gasoline-powered engines. In combination with hybridization, the technology can additionally reduce fuel consumption. A further trend for the past few years now has been downsizing (lower displacement, fewer cylinders) in combination with turbocharging. OBJECTIVE: LESS FRICTION Downsized engines with fewer moving parts are a prime example of reducing friction within the engine. On average, some 25 % of total fuel energy in any combustion engine is lost to friction. The greatest friction losses occur at the broad frictional surfaces of the piston assembly. With tighter manufacturing tolerances, new bearing technologies, and innovative surface treatments, engine manufacturers are pulling out all the engineering stops. Combining these approaches with a modern additive-enhanced, low-viscosity motor oil yields a massive reduction in friction compared to SAE 10W/40 viscosity oils. SAE 0W GENERATION The MOTOREX Car Line 0W-generation lowviscosity motor oils have been developed especially for the latest engine types. They form a lubricant film just 2 µm thick, i.e. just half as thick as hitherto. The result: ever more efficient engines and reduced CO 2 emissions. 10

NEW MOTOREX XERUS LH SAE 5W/30 Protection and performance with improved friction values: multi-use and brand-specific 0W-generation motor oils from MOTOREX. EXCEPTIONAL FUEL ECONOMY MINIMAL CO 2 EMISSIONS BETTER PROTECTION AGAINST WEAR AGING AND OXIDATION RESISTANT SUPPRESS LOW-SPEED PRE-IGNITION (LSPI) MEET ALL MANUFACTURERS’ APPROVALS FOR THE LATEST ENGINE GENERATION Saving fuel is a hot topic for heavy duty diesels as well: With its XERUS LH, MOTOREX is launching a new generation of ultra- fuel-economy motor oils for commercial vehicles. Here too, the reduced hightemperature viscosity to API-FA-4 or MB 228.61 standards facilitates fuel savings and reduced CO 2 emissions.
