AeroShell Turbine Oil 390 is a 3 mm²/s synthetic diester turbine oil supplied in a single-quart container. It is formulated to help improve auxiliary power unit (APU) starting reliability following cold-soak conditions, with lower low-temperature viscosity than a conventional 5 mm²/s turbine oil.

The oil incorporates additives intended to support thermal and oxidation stability together with load-carrying capability. It was developed as an improved low-viscosity oil for British turbojet engines and is also used where the applicable approved documentation specifies AeroShell Turbine Oil 390.
