AeroShell Oil 120 is a straight mineral oil used primarily during break-in of most four-stoke cycle certificated aviation piston engines. This unique oil is blended from selected high viscosity index base stocks and contain pour point depressants for improved fluidity at cold temperatures. It also has the following benefits:

• Contain a pour point depressant for improved fluidity at cold temperatures
• Compatible with most other aviation oils
• Available in a full range of viscosity grades to meet your requirements

Application

• Four-stroke cycle certificated aircraft reciprocating piston engines when use of an ashless dispersant (AD) oil is not required
• Used for break-in of most certificated four-stroke cycle aviation piston engines. The duration and lubrication for break-in vary, so aircraft owners should refer to the original engine manufacturer and/or overhaul facility for specific recommendations
• antique aircraft, which operate with very low oil temperatures or in aircraft that, have previously been run exclusively on mineral oil for an extend period of time
