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.
Number 4 fuel oil is a commercial heating oil for burner installations not equipped with preheaters. It may be obtained from the heavy gas oil cut. Number 5 fuel oil is a residual-type industrial heating oil requiring preheating to 170 â 220 Â°F (77 â 104 Â°C) for proper atomization at the burners.umber 4 fuel oil is a commercial heating oil for burner installations not equipped with preheaters.
