OIL VISCOSITY
Choose the viscosity according to the temperature as shown in the appropriate oil viscosity chart (Figure 21). See
following NOTE.
NOTE: Use engine oil with API classification CF for diesel engines.
Using multi-grade oils (5W-20, 10W-30, and 10W-40) will increase oil consumption. If multi-grade oil is used, check the
oil level more frequently.
