In petrol (gasoline) engines, the top piston ring can expose the motor oil to temperatures of 160 Â°C (320 Â°F). In diesel engines the top ring can expose the oil to temperatures over 315 Â°C (600 Â°F). Motor oils with higher viscosity indices thin less at these higher temperatures.
Typically, the viscosity is reported at one of two temperatures, either 40Â°C (100Â°F) or 100Â°C (212Â°F). For most industrial oils, it is common to measure kinematic viscosity at 40Â°C because this is the basis for the ISO viscosity grading system (ISO 3448).ikewise, most engine oils are typically measured at 100Â°C because the SAE engine oil classification system (SAE J300) is referenced to the kinematic viscosity at 100Â°C (Table 1). Additionally, 100Â°C reduces the rise of measurement interference for engine oil soot contamination. Figure 2.
