AeroShell 100 Mineral Oil

AeroShell 100 Mineral Oil is a high-quality pure mineral lubricant, blended with selected high viscosity index base oil. This oil contains no additives, except for small quantities of pour point depressant (which helps improve fluidity at very low temperatures) and an antioxidant, ensuring a clean and specific composition for certain applications.

Essential Use for New and Classic Engines

AeroShell 100 Mineral Oil is approved for all civil aircraft piston engines where the use of an oil not containing a dispersant additive is required. However, its most critical and common application is during the break-in of a new or recently overhauled aviation piston engine. During this initial phase, an oil without dispersant additives is crucial to allow internal component surfaces to seat correctly.

Effective Protection and Reliability

The specially blended high viscosity index base oil in AeroShell 100 Mineral Oil has been designed to provide effective protection to engine components compared to conventional mineral oil. This helps ensure total confidence and peace of mind, knowing your aircraft will operate reliably between scheduled overhauls.

Product Benefits:

• High viscosity index base oils used in AeroShell oils maintain their viscosity and protect engine components more effectively under the high shear stresses an engine applies to lubricants.
• Approved for all civil aircraft reciprocating engines used for break-in operations or older generation engines requiring non-additive type engine oils (refer to manufacturer's recommendations).
• Provides compatibility with other approved aircraft piston engine oils. Since AeroShell 65, 80, 100, and 120 Oils are fully approved to SAE J-1966 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 oils are inherently storage stable. Provided they have been stored and handled correctly, prolonged storage has no effect on their quality, properties, or performance.

Specifications and Approvals:

• Approved to SAE J-1966
• Listed on the corresponding Qualified Products List (QPL).

Frequently Asked Questions:

When should I use a pure mineral oil like AeroShell 100?
Primarily, for the initial break-in period of new or freshly overhauled aviation engines, or for older engines where the manufacturer specifies the use of a non-dispersant additive oil.

Can I use AeroShell 100 Mineral Oil permanently in my engine?
Typically, after the break-in period, it is recommended to switch to an ashless dispersant oil (like AeroShell W100) for continuous use, unless your engine manufacturer specifies otherwise for older engines.
