The oil must be able to keep the piston moving smoothly at cold temperatures (when the engine first starts up) and also at the normally high operating temperature of the cylinders. Lubricate over a wide temperature range." (Thibault, 2001).Seal piston and liner for optimum engine efficiency. Lubricate engine moving parts to reduce friction and prevent wear.Without oil, the piston would not be able to move in the cylinder-the engine would seize up and be ruined. The oil is a lubricant-a slippery liquid that allows the piston to slide freely within the cylinder. In order to keep the pistons moving smoothly in the cylinders, there is a thin film of motor oil between the piston rings and the cylinder wall. The internal combustion engine that powers your family's car has moving parts that work at high temperatures for billions of cycles over its lifetime.
