AeroShell Turbine Oil 3 is a 3 mm2/s mineral turbine oil, developed for early pure jet engines and is still approved for some versions of these engines plus Turbomeca Astazou, Artouste, Turmo, Bastan and Marbore engines.
AeroShell Turbine Oil 3 is widely used for inhibiting fuel systems and fuel system components during storage.
AeroShell Turbine Oil 3 is an analogue to the Russian Grade MK-8 and can therefore be used in engines which require the use of MK-8. It is also used as the mineral turbine oil component in the mixture of mineral turbine oil and piston engine oil used in Russian turbo-prop engines.
