MIL-PRF-7808L - Synthetic Base Aircraft Turbine Engine Lubricating Oil

We perform testing according to military specification MIL-PRF-7808, which covers the requirements for two grades of aircraft turbine engine lubricating oil, identified as Grade 3 (NATO Symbol 0-148) and Grade 4 (NATO Symbol 0-163).

The lubricating oil is intended for use in specific models of aircraft turbine engines, helicopter transmissions, accessory and auxiliary power units, and other types of equipment that require a synthetic base oil. Grade 3 is intended for normal use unless otherwise specified. Grade 4 is intended for applications which require higher viscosity and greater thermal stability.
