AeroShell Oil 65 is straight mineral oils blended from selected high viscosity index base oils. These oils do 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 Oils 65 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 65 have been designed to provide effective protection to engine components compared to conventional mineral oils. This helps ensure complete confidence and peace of mind knowing that your aircraft will perform reliably in between scheduled overhauls.
AeroShell Oils 65 is produced to meet fully the SAE specification J-1966 (Grades SAE 30, 40, 50 and 60 respectively). Furthermore, it has 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 Defence. 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.
