Aeroshell “Straight” oil AeroShell 100

AeroShell (straight mineral) Oil (SAE 50) contains a minimum quantity of additives.

This oil is especially appropriate during the break-in period of most new or recently overhauled four-stroke aircraft piston engines.
AeroShell Oil 100 is a straight mineral oil blended from selected high viscosity index base oils. 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, they 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 oils in AeroShell Oil 100 has been designed to provide effective protection to engine components compared to conventional mineral oils. This ensures complete confidence and peace of mind knowing that your aircraft will perform reliably in between scheduled overhauls.
