COMPOSITION OF ENGINE OIL FOR AUTOMOTIVE ENGINE HAVING LOW FRICTION COEFFICIENT TO OFFER GOOD WEAR RESISTANCE AND IMPROVED ENGINE FUEL ECONOMY PERFORMANCE

摘要

PURPOSE: A composition for engine oil for use in automotive engine having a low friction coefficient is provided which has good wear resistance owing to a synergic effect by various additive ingredients and persistently improves engine fuel economy performance by reducing friction of an engine slider. CONSTITUTION: The composition for engine oil comprises: 50 to 90 wt% of base oil; 0.01 to 5 wt% of an antiwear agent; 0.01 to 5 wt% of organic molybdenum; 0.01 to 3 wt% of a friction modifier; 0.01 to 5 wt% of a metal-based detergent and dispersant; and 0.01 to 10 wt% of an additive containing a viscosity index enhancer.
