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.
1 Two-stroke oil is expensive, and you need about 4 ounces of it per gallon of gas. 2  You would burn about a gallon of oil every 1,000 miles if you used a two-stroke engine in a car. The pollution comes from two sources. 2  The first is the combustion of the oil. 3  The oil makes all two-stroke engines smoky to some extent, and a badly worn two-stroke engine can emit huge clouds of oily smoke.
