AeroShell Fluid 2XN is primarily used as an ingredient of AeroShell Fluid 2F (1 part ASF 2XN with 3 parts ASO 100), but can be used undiluted to provide additional protection for piston engines after run-out on AeroShell Fluid 2F, by spraying exhaust ports, rocker arms, accessories.
For aircraft gas turbine engines a mixture of one part of AeroShell Fluid 2XN to three parts of AeroShell Turbine Oil 2 is required. Detailed instructions for inhibiting turbines are given in specification MIL-E-5607F.
The ashless anti-corrosion additive package together with the highly refined mineral base oil protects the engine by minimizing the effects of humidity and neutralizing the acidic components of engine oil and, in piston engines, the combustion byproducts as well.
