If you opened your engine cowl and saw oil dripping out of the compressor inlet, you have reason for more concern. This indicates a larger amount of oil is leaking out of the tank and accumulating inside the engine where the bearings are. When the oil reaches the level of the shaft, it leaks out. You want to get that addressed.
Hopefully you are checking your oil faithfully. If it is suddenly off the stick on a cold engine, just motor that engine for 30 seconds and check again. You should be good to go. KA
