When operating aircraft in high-temperature environments, engine performance and longevity depend significantly on the quality of the oil used. That’s why aviation professionals across hot regions consistently recommend AeroShell Oil W120. This single-grade ashless dispersant oil is specially formulated for air-cooled piston engines, and its characteristics make it ideal for the demanding conditions of hot climates.

Exceptional Thermal Stability

One of the key reasons AeroShell Oil W120 is preferred in hot climates is its excellent thermal stability. High temperatures can cause many oils to break down prematurely, leading to sludge formation, poor lubrication, and engine wear. However, AeroShell W120 is engineered to maintain viscosity and resist thermal breakdown even in soaring temperatures. This stability ensures smooth operation during extended flights and ground idling under the sun.

Superior Viscosity for High Heat

The "W" in W120 stands for "Weight," and the 120 represents its viscosity rating. With a high viscosity index, this oil maintains a protective film between engine parts, even under high stress and elevated temperatures. This is particularly important in hot climates where thinner oils may fail to provide sufficient lubrication. AeroShell W120 reduces metal-to-metal contact, protecting against friction and wear in both low-speed taxiing and high-RPM cruising.

Trusted Performance in Desert and Tropical Regions

From the Middle East’s desert heat to the tropical zones of Southeast Asia, AeroShell W120 has been the trusted choice for decades. It performs reliably in regions where ambient temperatures often exceed 40°C (104°F), offering consistent engine protection and minimizing the risk of oil oxidation or vapor loss. Aircraft operators in the UAE, India, Africa, and Australia rely on this oil for dependable engine performance in extreme weather.

Ashless Dispersant Formula Enhances Engine Cleanliness

AeroShell Oil W120 features an ashless dispersant formulation, which helps keep engine components cleaner over time. The dispersants suspend carbon deposits and contaminants in the oil, preventing sludge build-up and reducing maintenance intervals. In dusty and hot climates, where airborne particles are more prevalent, this feature is especially valuable in protecting the engine from internal corrosion and fouling. 

OEM Approved and Widely Used

Leading engine manufacturers such as Lycoming and Continental approve the use of AeroShell W120. Its compatibility with major aircraft engine types makes it a go-to product for general aviation, flight schools, and agricultural aircraft operating in hot weather. It also complies with SAE J1899 and FAA airworthiness standards.

Conclusion

For pilots and maintenance teams working in high-temperature environments, AeroShell Oil W120 stands out as a top-tier aviation lubricant. Its high viscosity, thermal resilience, and ashless formula ensure reliable engine protection in the harshest climates. Whether you're flying over deserts or in tropical airstrips, using AeroShell W120 is a smart and proactive choice to safeguard your aircraft's engine.
