AeroShell straight mineral oils are blended from selected high viscosity index base stocks. These oils do not contain additives except for a small quantity of pourpoint depressant (which is added when improved fluidity at very low temperature is required) and an anti-oxidant.
Main Applications
- AeroShell Oils are available in four different viscosity grades: AeroShell Oil 65 – AeroShell Oil 80 – AeroShell Oil 100 -AeroShell Oil 120.
- The suffix for each grade corresponds to the viscosity of the oil at 2100F in Saybolt Universal Seconds.
- The appropriate grades of these AeroShell Oils are approved for use in four-stroke cycle (four-cycle) certified aircraft reciprocating piston engines (except Porsche)andother aircraft radial engineswhichuse oil to specificationSAE J-1966 (MIL-L-6082) and which do not require use ofan oil containing a dispersant additive. AeroShell Oils areused primarily during break-inof most new or recentlyoverhauled four-stroke cycle aviation piston engines. Theduration and lubrication recommendations for break-in vary,so operators should refer to the original enginemanufacturer and/or overhaul facility for specificrecommendations.
Specifications, Approvals & Recommendations
- The U.S. Specification SAE J-1966 replaces MIL-L-6082E.
- Although it was planned to replace the British Specification DERD 2472 with a DEF STAN specification this has now been put into abeyance and instead the SAE specificationhas been adopted.
- U.S. : Approved J-1966 SAE Grade 50
- British : Approved J-1966 SAE Grade 50
- French : (AIR 3560/D Grade SAE 50)
- Russian : MS-20
- NATO Code : O-117 Obsolete
