AeroShell Oil 100 is a straight mineral oil blended from selected high viscosity index base oil. This oil does not contain any additives except for very small amounts of pour point depressant (which aids to improve fluidity at very low temperatures) and an anti-oxidant.
AeroShell Oil 100 is approved for all aviation piston engines of civil aircraft when the use of an oil not containing a dispersant additive is required; however, it should also be used during the break-in of a new aviation piston engine or those recently overhauled.
The specially blended High Viscosity Index base oil in AeroShell Oil 100 has been designed to provide effective protection to engine components compared to conventional mineral oil. This helps ensure complete confidence and peace of mind knowing that your aircraft will perform reliably in between scheduled overhauls.
AeroShell Oil W100 Plus and W 80 Plus are new single grade oils that combine proven AeroShell ashless dispersant technology with advanced antiwear additives. They are the oils for pilots who want a single grade that delivers extra protection and performance. AeroShell Oil W 100 Plus and W 80 Plus brings together the best qualities of two of the world's best-selling four cycle aviation oils.
They have the single grade, ashless dispersant performance found in AeroShell W 100 and W 80 and the anti-wear/anti-corrosion additives of AeroShell Oil W 15W50 Multigrade. Their single grade heritage means outstanding resistance to heat, especially in the summer months. Their ashless dispersant formulation helps reduce deposits of harmful metallic ash in combustion chambers. And their advanced additives work against rust, corrosion and wear in a way no other single grade does. There are simply no better single grade aviation oils.
AeroShell Oils W80, W100 and W120 are ashless dispersant oils specifically developed for aviation piston engines. They combine non-metallic additives with selected high viscosity index base oils togive exceptional stability, dispersancy and anti-foaming performance. 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 equates to AeroShell Oil W80, W100 and W120 respectively.
Traditionally, the choice is associated with climatic zones - AeroShell W80 for cold climate regions (-17 - 21°C), AeroShell Oil W100 for temperate regions (15 - 30°C) and AeroShell Oil W120 for warmer climates (above 26°C).
