Narrative:
Airport fueler was putting jet fuel in the PA31-350. I stopped him after he put 6 gallons in the right main tank. I had him top off with 100LL; wrongfully thinking a small amount would not be a problem. I flew the trip to ZZZ and back with no incident. When being parked I saw a red altitude and altitude inoperative light come on the right engine; the one with the jet fuel in it. I do not remember any other negative engine indications. Being at the gate; I shut the engine down. I reported to the director of operations and the director of maintenance that I had flown the plane with 6 gallons of jet a in a 56 gallon tank. The next day I found oil on the ground below the right engine.
