Exxon Instrument Oil

SPECIAL FLUIDS

Exxon Instrument Oil is a low-viscosity rust-inhibited petroleum-base instrument oil with excellent low-temperature characteristics. It contains additives to inhibit oxidation and to increase load-carrying capacity. Exxon Instrument Oil is approved against MIL-PRF-7870 and meets the requirements of Aeroproducts Specification No. 1-40004, which references MIL-PRF-7870 and applies to Aeroproducts 606 propellers and components.
