LUBRICATION SYSTEM
The lubrication system consists of an oil pan, dipstick, pump, oil pressure sender, and filter. The oil pan is a reservoir for
engine lubricating oil. Engine oil lubricates, cleans, cools, seals, and preserves engine parts. The dipstick indicates oil level
in the oil pan. A pump draws oil from the oil pan and through a screen that blocks large objects from entering the oil pump
and oil cooler. The oil then passes through a spin-on type filter where small impurities are removed. From the filter, oil
enters the engine and is distributed to the engine's internal moving parts through internal passageways. Oil is also supplied
to the turbocharger. After passing through the engine, the oil returns to the oil pan. The lower GSC display indicates oil
pressure sensed by the oil pressure sender in the engine. The engine will shut off automatically if the oil pressure drops
below 30 psi (207 kPa) and the red LOW OIL PRESSURE indicator on the GSC will flash. The oil level can be checked
with the engine running.
