Aeroshell W120 Piston Engine Oil - 5 Litres
 
AeroShell Oil W120 is an ashless dispersant oil specifically developed for aviation piston engines. Non-metallic additives combined with selected high viscosity index base oils give exceptional stability, dispersancy and anti-foaming performance. While there is no general rule for every engine type when choosing the correct grade of oil, traditionally AeroShell Oil W120 is selected for warmer climates above 26° C.
 
Product Benefits
 
  • Promotes engine cleanliness - the non-ash forming, polymeric additive was developed to help eliminate the harmful combustion chamber deposits that occur during normal operation
  • High viscosity index base oils - maintain their viscosity and help protect engine components more effectively under the high shear stresses that an engine places on lubricants
  • Compatibility with other approved aircraft piston engine oils - fully approved to SAE J1899
  • Stable in storage - prolonged storage does not have any effect on their quality, properties, or performance
     
How to use AeroShell Oils W80, W100, and W120
 
AeroShell W Oils can be used in four-stroke (four-cycle) certified reciprocating piston engines, including fuel-injected and turbocharged engines. Radial engine operators tend to use AeroShell Oil W120 in warmer weather, while AeroShell Oil W100 and AeroShell Oil W 15W-50 should be used in cooler temperatures.
 
For Lycoming and Continental flat engines, AeroShell Oil W100 or AeroShell Oil W 15W-50 are the most common choices with AeroShell Oil W80 used during the colder months.
 
Check with your engine manufacturer or rebuilder to find out if AeroShell Oils W80, W100, or W120 can be used during break-in. While many engine manufacturers and rebuilders and overhaul agencies say to use straight mineral oils, some say that either ashless dispersant or straight mineral oil can be used for break-in – for example, for Lycoming O-320H and O/LO360E. For all turbocharged Lycoming engines, ashless dispersant oils are recommended for break-in.
 
AeroShell W Oils shouldn’t be used in automotive engines. If you’re using an automotive engine that’s been converted for use in an aircraft, check with the engine manufacturer to find out which oil you should use.
 
Single Grade Ashless Dispersant Oils
 
AeroShell Oils W80, W100, and W120 are ashless dispersant oils specifically developed for aviation piston engines. They reap the performance benefits of combining non-metallic additives with selected high viscosity index base oils. No general rule exists for every engine type when choosing the correct grade of oil; however, based on the average ambient outside temperature at engine start-up, the most common grades are SAE 40, SAE 50, and SAE 60, which equate to AeroShell Oil W80, W100, and W120 respectively.
 
Traditionally, the choice is associated with climatic zones: AeroShell W80 for cold climate regions (-17 to 21°C), AeroShell Oil W100 for temperate regions (16 to 32°C), and AeroShell Oil W120 for warmer climates (above 26°C)
 
AeroShell Oils W80, W100, and W120 are produced to meet fully the SAE specification J1899 (Grades SAE 40, 50, and 60 respectively).
