It must also cool the engine by absorbing heat, seal gaps between pistons and cylinders to maintain compression, and clean internally by suspending contaminants until they can be filtered out. The number preceding the 'W' indicates cold-weather performance—the lower the number, the better the flow in frigid conditions.

Synthetic oils, however, are engineered from chemical compounds to provide superior performance; they offer greater viscosity stability, enhanced resistance to oxidation, and improved performance in extreme cold or heat. You will often see codes such as 20W-50 or 10W-40.
The number after the dash signifies the viscosity at high operating temperatures. This specialized fluid is not merely a lubricant but a critical component that ensures the safety, efficiency, and longevity of every flight.
Effective Contaminant Control Strategies for Aircraft Oil
The primary role of this fluid is to create a thin film between moving metal parts, reducing friction and preventing wear. Modern aviation relies on a sophisticated blend of science and engineering, and at the heart of this complex machinery lies a substance often overlooked: aircraft oil.
