The operating temperature range of the excavator is the factor that will determine whether I use a multigrade or monograde oil. If my excavator is required to operate in freezing temperatures in winter and tropical conditions in summer, then multigrade oil will be required to maintain oil viscosity within optimum limits across this wide operating temperature range.
