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.
Avoid overfilling your crankcase. Too much oil can cause the same type of engine damage as not having enough. Air bubbles form in the oil, reducing overall lubrication. The resulting friction and metal-to-metal contact can cause premature part failure.ark oil is not only dirty; it has also lost much of its ability to coat and protect engine components. Manufacturers recommend changing the oil in your small engine after every 25 hours of operation. For a new engine, you'll also need to change the oil after the first five hours of operation.
