Aeroshell Straight Grade Engine Oils

AeroShell Oils 65, 80, 100, and 120 are straight mineral oils blended from selected high-viscosity index base oils. These oils do not contain any additives except for very small amounts of pour point depressant (which helps improve fluidity at very low temperatures) and an anti-oxidant.

AeroShell Oils 65, 80, 100 and 120 are approved for all aviation piston engines of civil aircraft when the use of an oil not containing a dispersant additive is required; however, they should also be used during the break-in of a new aviation piston engine or those recently overhauled.

Compared to conventional mineral oils, the specially blended High-Viscosity Index base oils in AeroShell Oil 65, 80, 100, and 120 have been designed to effectively protect engine components. This helps ensure complete confidence and peace of mind, knowing that your aircraft will perform reliably between scheduled overhauls.

AeroShell Oils 65, 80, 100, and 120 are produced to fully meet the SAE specification J-1966 (Grades SAE 30, 40, 50, and 60, respectively). Furthermore, they all have approval for military qualification. They are listed on the Qualified Products List (QPL) issued by the US Navy and the Technically Acceptable Products List (TAPL) issued by the UK Ministry of Defence. The blending plants employed to manufacture these oils also hold the approval of the specification authorities, ensuring that the high quality standard is always maintained.

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 that an engine places on lubricants.
• Approved for all reciprocating engines of civil aircraft used for running-in operations or older generation engines requiring non-additive type engine oils (refer to manufacturers recommendations).
• It provides compatibility with other approved aircraft piston engine oils. Since AeroShell Oils 65, 80, 100 and 120 are fully approved to SAE J-1966 and are listed on the relevant Qualified Products List (QPL), elaborate precautions are not needed when changing from similarly approved aircraft engine oils, as long as these oils are qualified products.
• AeroShell Oils are inherently stable in storage. Provided that they have been stored and handled correctly, prolonged storage does not affect their quality, properties, or performance.
