AeroShell W100 Oil

AeroShell W100 Oil is an ashless dispersant oil developed specifically to meet the needs of aviation piston engines. Its formulation combines carefully selected non-metallic additives with high viscosity index base oils, resulting in exceptional stability, superior dispersion, and excellent anti-foaming performance.

Selecting the Correct Grade and Application

There is no single general rule for every engine type when choosing the correct oil grade. However, based on the average ambient outside air temperature at engine start, the most common grades are SAE 40, SAE 50, and SAE 60, which equate to AeroShell Oil W80, W100, and W120 respectively. AeroShell W100 is specifically designed for use in temperate regions (15 - 30°C), ensuring optimal performance in these conditions.

Key Product Benefits

AeroShell W100 Oil offers a number of crucial benefits for the health and longevity of your aviation engine:

• Promotes engine cleanliness. The ashless polymeric additive was developed to help eliminate harmful combustion chamber deposits that occur during normal operation, contributing to a cleaner, more efficient engine.
• The high viscosity index base oils used in AeroShell W Oils maintain their viscosity and help to protect engine components more effectively under the high shear stresses an engine applies to lubricants. This ensures consistent and robust lubrication.
• Provides compatibility with other approved aircraft piston engine oils. Since AeroShell W80, W100, and W120 Oils are fully approved to SAE J-1899 and listed on the corresponding Qualified Products List (QPL), no complicated precautions are necessary when changing from similarly approved aircraft engine oils, provided these oils are qualified products.
• AeroShell W Oils are inherently storage stable. Provided they have been stored and handled correctly, prolonged storage has no effect on their quality, properties, or performance, ensuring a long shelf life without degradation.

Specifications and Approvals:

• Approved to SAE J-1899
• Listed on the corresponding Qualified Products List (QPL).

Frequently Asked Questions:

Can I use AeroShell W100 in cold or very hot climates?
AeroShell W100 is optimized for temperate regions (15-30°C). For colder or hotter temperatures, it is recommended to consult the AeroShell grade selection guide (W80 for cold, W120 for hot).

What does "ashless" mean in an aviation oil?
It means the oil does not contain metallic additives that can form ash deposits in combustion chambers, which helps maintain engine cleanliness and reduces the possibility of pre-ignition.
