Extreme engine operation Synthetic oils meeting SAE 10W-30 and complying with oil quality requirements are recommended for driving in areas of sustained temperature extremes (hot or cold), when towing a trailer over long distances, and for prolonged driving in mountainous areas. American Petroleum Institute (API) symbol The API Service Symbol "donut" is divided into three parts: The upper section describes the oil's performance level. The center identifies the oil's viscosity. The lower section indicates whether the oil has demonstrated energy-conserving properties in a standard test in comparison to a reference oil. pg. 180 Engine specifications Engine designation Output kW/rps hp/rpm Torque Nm/rps ft. lbs./rpm No. of cylinders Displacement (liters/cubic inches) Bore (mm/in.)

The resulting increase in air flow raises pressure in the intake manifold and increases engine power over that developed by the normally-aspirated engine. The charge air cooler (which resembles a radiator) is located between the turbo-compressor and inlet manifold. Fuel system The engine is equipped with a multiport fuel injection system. pg. 181 Electrical system General information 12-volt system with voltage controlled generator.
