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 Oils 100 is produced to meet fully the SAE specification J-1966 (Grades SAE 50 respectively). Furthermore, it has military qualification approval and is listed on the Qualified Products List (QPL) issued by the US Navy and on the Technically Acceptable Products List (TAPL) issued by the UK Ministry of Defence. The blending plants employed to manufacture this oil also holds the approval of the specification authorities and this ensures that the high quality standard is always maintained.
