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.
But don't think that the coolant gauge will tell you this information - it won't. As a general rule of thumb, after the car is warmed up, oil tends to be a few degrees warmer than the coolant (usually 10-15 degrees Fahrenheit). However, it takes much longer for oil to come up to temperature than coolant. When you start your car in the morning, most of us are wise enough to not romp on the car until the coolant gauge is up to operating temperature. This is certainly better than romping on it cold, but it's still not quite ideal.
