Engine Oil: Testing and Inspection

OIL LEVEL AND MUDDINESS
^ Before starting the engine, check the oil level. If the engine is already started, stop it and allow 10 minutes before checking.





^ Check that the oil level is within the range shown in the figure.
^ If it is out of range, add oil as necessary.
^ Check the oil for white turbidity or remarkable contamination.
^ If the oil becomes turbid and white, it is highly probable that it is contaminated with coolant. Diagnose the problem and correct as necessary.
