The real question I think everyone wants answered though, is where did the Navy get this mystery lube, and what is it actually approved for…?
E-2C 2 × Allison / Rolls-Royce T56-A-427
E-2D 2 x T56-A-427A (E-2D) turboprop
Both need MIL-PRF-23699 oil.
The reporter, with much better resources than us could have spent five minutes to it look up. The oil is not a mystery oil, it obviously came through the navy supply chain (good luck finding a mechanic willing to go off the base and buy the oil on his credit card) and the type they used is known from their ordering invoices.
I wouldn't want to be the guy in charge of that squadron's maintenance.
