Aeroshell 100 is a low density piston engine oil ideal for use during colder months and is recommended for use in new engines. AeroShell 100 is a straight mineral oil (SAE 40) blended from selected high viscosity index base oils.
AeroShell 100 is approved for all aviation piston engines of civil aircraft when the use of an oil not containing a dispersant additive is required. Aeroshell 100 oil should also be used during the break-in of a new aviation piston engine or those recently overhauled. AeroShell 100 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. Specially blended High Viscosity Index base oil in AeroShell Oil 100 is 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. AeroShell 100 is produced to meet fully the SAE specification J-1966 (Grades SAE 30, 40, 50 and 60 respectively). Military qualification approval and are 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 Defense. The blending plants employed to manufacture these oils also hold the approval of the specification authorities and this ensures that the high quality standard is always maintained.
