Exxon Aviation Oil Elite 20W-50 is U.S. Military approved under SAE J1899, which replaced MIL-L-22851D and is listed in the U.S. Military Qualified Products List QPL-1899. It is approved by and included in the Qualified Products Lists of Teledyne Continental, and Textron Lycoming and it is designed to satisfy the requirements of all opposed piston engine manufacturers. It provides an alternate means of compliance with FAA AD 80-04-03-R2 par.b.1.

New or newly overhauled aircraft engines should be broken in according to the engine builder’s recommended procedure. Many engine manufacturers advise running in on straight mineral oils for the first 25 to 50 hours of operation. In all cases, however, the engine manufacturers recommendations should be followed, since the run in procedure can vary from engine to engine.

Aviation Oil Elite is compatible with non-dispersant mineral oils as well as other ashless-dispersant oils that meet the requirements of MIL-L-22851D/SAE J1899. It can also be used in high-time engines that have previously used a straight mineral oil. In this case it is advisable to carry out the oil-screen inspection recommended by the engine manufacturer.

My mechanic told me that this oil has more of the good stuff that my O-320 needs than other oils. It is a more expensive oil, time will tell if it was worth it. No filter on my Cub, just a screen. I change oil every 25hrs. I use no oil for the first 20 hrs, and then 1/2 qrt over the next 5 hrs. I havn't tried any other oil, so I have nothing to compare it with.
