LUBRICANTS, ENGINE

Engine	Service interval (km/miles)	Volume (liters)	Grade	Viscosity	Part number
Gasoline	12.000/7.500	Approx. 5.8	ILSAC GF-4 API SL / ACEA A1/B1	SAE 5W-30	1161754, -755, -756

CLASSIFICATION OF MAIN BEARINGS

The marking is stamped in the engine block and crankshaft. The classification marking is in the engine block above the oil cooler and crankshaft. The classification shall be read from the digit 1 to 7.

The first letter after the digit 1 is the classification of main bearing 1. The bearing positions are numbered starting at the engine's leading edge.

	Class A block small diameter		Class B block average diameter		Class C block large diameter
	Block	Intermediate section	Block	Intermediate section	Block	Intermediate section
Class A crankshaft small	Yellow medium	Yellow medium	Yellow medium	Blue thick	Blue thick	Blue thick
Class B crankshaft medium	Red thin	Yellow medium	Yellow medium	Yellow medium	Yellow medium	Blue thick
Class C crankshaft large	Red thin	Red thin	Red thin	Yellow medium	Yellow medium	Yellow medium
