2011 Chevrolet Cruze incorporates fuel saving variable displacement oil pum

One of many Cruze incremental engine technologies to improve fuel efficiency is the variable displacement oil pump. The pump body pivots (blue lines) causing the vanes (red lines) to move resulting in just the right volume of oil being pumped. When less oil is pumped less energy is needed which ultimately saves fuel. The variable displacement pump is standard on the Ecotec 1.4L turbo engine. The oil pump in the engine of the 2011 Chevrolet Cruze takes a laid-back approach to its work, delivering the precise amount of oil needed during all driving conditions. That requires the engine to work less versus a conventional pump and ultimately saves fuel.
