Narrative:

During my preflight inspection it appeared that the right hand engine oil quantity was a little low but still within limits. I asked a mechanic to also observe the right hand engine sight glass indicator. The mechanic confirmed that the oil level was within limits and was enough to fly a round trip from pit to uca. The flight to uca was routine. On the return trip, on takeoff roll just after V-1 the aural warning sounded, followed by the 'oil pressure 2' red map light. The oil pressure gauge indicated normal. We advised ATC that we wanted to return to the airport. ATC cleared us to return to uca. As power was reduced on the engines, the map light went out and oil pressure indicated normal. Our station maintenance serviced the right engine with 3 quarts of oil. The engine was run up with normal indications. Passenger were reboarded and a routine flight to pit was conducted.

Title: AN ACR CREW HAD TO RETURN LAND WITH A LOW OIL PRESSURE WARNING.

Narrative: DURING MY PREFLT INSPECTION IT APPEARED THAT THE R HAND ENG OIL QUANTITY WAS A LITTLE LOW BUT STILL WITHIN LIMITS. I ASKED A MECH TO ALSO OBSERVE THE R HAND ENG SIGHT GLASS INDICATOR. THE MECH CONFIRMED THAT THE OIL LEVEL WAS WITHIN LIMITS AND WAS ENOUGH TO FLY A ROUND TRIP FROM PIT TO UCA. THE FLT TO UCA WAS ROUTINE. ON THE RETURN TRIP, ON TKOF ROLL JUST AFTER V-1 THE AURAL WARNING SOUNDED, FOLLOWED BY THE 'OIL PRESSURE 2' RED MAP LIGHT. THE OIL PRESSURE GAUGE INDICATED NORMAL. WE ADVISED ATC THAT WE WANTED TO RETURN TO THE ARPT. ATC CLRED US TO RETURN TO UCA. AS PWR WAS REDUCED ON THE ENGS, THE MAP LIGHT WENT OUT AND OIL PRESSURE INDICATED NORMAL. OUR STATION MAINT SERVICED THE R ENG WITH 3 QUARTS OF OIL. THE ENG WAS RUN UP WITH NORMAL INDICATIONS. PAX WERE REBOARDED AND A ROUTINE FLT TO PIT WAS CONDUCTED.
