AeroShell Oil 80

AeroShell Oils are available in four different viscosity grades:

• AeroShell Oil 80 The suffix for each grade corresponds to the viscosity of the oil at 210F in Saybolt Universal Seconds.
• The appropriate grades of these AeroShell 80 Oils are approved for use in four-stroke cycle (four-cycle) certified aircraft reciprocating piston engines (except Porsche) and other aircraft radial engines which use oil to specification SAE J-1966 (MIL-L-6082) and which do not require use of an oil containing a dispersant additive. AeroShell Oils are used primarily during break-in of most new or recently overhauled four-stroke cycle aviation piston engines. The duration and lubrication recommendations for break-in vary, so operators should refer to the original engine manufacturer and/or overhaul facility for specific recommendations.
