Your question "MIL-PRF-7808" is incomplete—it does not ask a specific question about the specification.

MIL-PRF-7808 is referenced in the indexed passages as a Department of Defense specification covering lubricating oil for aircraft turbine engines, synthetic base, in two grades (Grade 3 and Grade 4) [MIL-PRF-7808 para 6.3.3]. The specification includes requirements for trace metal content [MIL-PRF-7808 para 4.4.10], storage stability, compatibility, and sediment limits [MIL-PRF-7808 para 4.4.10]. Items qualified to MIL-PRF-7808 require recertification every two years [MIL-PRF-7808 para 6.3.3].

Please rephrase your question to ask what you need to know about MIL-PRF-7808 (for example: "What are the recertification requirements?" or "What is the maximum copper content allowed?").
