AeroShell Oil 80
AeroShell Oil 80 is crafted for use in engines during break-in periods, offering lower viscosity for reliable lubrication and flow in colder climates.
Features and benefits
Ideal for engine break-in
No additives except for a small quantity of pourpoint depressant and an antioxidant.
Suitable for colder climates
Lower viscosity for reliable lubrication and flow in colder climates (-17掳C to 21掳C / 1.4掳F to 69.8掳F ambient air temperature).

Applications
AeroShell piston engine break-in oils are available in three different viscosity grades: AeroShell Oil 80 - AeroShell Oil 100 - AeroShell Oil 120.
The suffix for each grade corresponds to the viscosity of the oil at 2100掳F in Saybolt Universal Seconds.
The appropriate grades of these AeroShell piston engine break-in 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 J1966 (MIL-L-6082) and which do not require use of an oil containing a dispersant additive. These 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.
