Castrol Aero J5

Castrol Aero J5 represents a new standard in high performance jet engine oils designed to exceed the requirements of MIL-PRF23699F (C/I). Aero J5 is formulated using premium quality polyol esters enhanced with an optimised additive package providing maximum performance.

Castrol Aero J5 is designed for use in turbofan, turboprop and turboshaft aircraft gas turbine engines, accessory equipment and ground based aeroderived gas turbines. Aero J5 offers superior thermal stability, excellent corrosion protection, improved load carrying capacity and reduced deposit forming tendency, when compared to other commercial oils.

Castrol Aero J5 is fully compatible with engine and accessory construction materials, including metals, elastomers and sealing compounds.
Aero J5 is fully compatible and miscible with oils approved to MIL-PRF-23699F. For this reason, changeover to Aero J5 can be carried out by topping-off. By virtue of the differences in seal swell characteristics between oils, the engine/accessory manufacturers` approval should be obtained for any proposed oil change.

Aero J5 benefits:

• Reduced deposit formation in engines
• Extended service use of oil
• Improved corrosion resistance under engine shutdown/storage
