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.
Modern diesel engines start in cold weather with very little effort.. The problem is that diesel jells at low temperatures. Below about 40Â°F, certain hydrocarbons in diesel turn gelatinous. Since an engine depends on aerosolizing fuel, you don't want goopy fuel, Ciatti explained.
