Fig. 43 Lubricating oil viscosity
As the viscosity of lubricating oil is dependent on
temperature, the choice of viscosity grade (SAE grade)
should be governed by the ambient temperature prevailing
at the engine operating site.
The optimum operating conditions are attained if you use
the oil viscosity figure shown here as a guide.
Should the temperature fall temporarily below the limits,
cold starting may be affected but the engine will not be
damaged.
In order to keep wear to a minimum, do not exceed the
operating limits for extended periods of time.
Oil changes dictated by the seasonal changes can be
avoided by using multi-grade lubricating oils. Multi-grade
oils also reduce fuel consumption.
