Narrative:

Upon setting power for takeoff, 'left engine oil pressure' warning light illuminated. Discontinued the takeoff, taxied back to the beginning of the runway and performed an engine run-up to takeoff power and all indications checked normal. Taxied onto the runway and after takeoff power was set, the 'left engine oil pressure' light came on again. Aborted the takeoff and returned to the gate. Now, the reason for not going to the gate after the first abort was due to ambiguity of company policy on aborted takeoffs. Because the run-up was normal, we attempted a second takeoff. Note: found out afterwards that maintenance logbook entry was required after first abort.

Title: SF340 CREW HAD AN OIL PRESSURE WARNING LIGHT ON TKOF ROLL IN PHL.

Narrative: UPON SETTING PWR FOR TKOF, 'L ENG OIL PRESSURE' WARNING LIGHT ILLUMINATED. DISCONTINUED THE TKOF, TAXIED BACK TO THE BEGINNING OF THE RWY AND PERFORMED AN ENG RUN-UP TO TKOF PWR AND ALL INDICATIONS CHKED NORMAL. TAXIED ONTO THE RWY AND AFTER TKOF PWR WAS SET, THE 'L ENG OIL PRESSURE' LIGHT CAME ON AGAIN. ABORTED THE TKOF AND RETURNED TO THE GATE. NOW, THE REASON FOR NOT GOING TO THE GATE AFTER THE FIRST ABORT WAS DUE TO AMBIGUITY OF COMPANY POLICY ON ABORTED TKOFS. BECAUSE THE RUN-UP WAS NORMAL, WE ATTEMPTED A SECOND TKOF. NOTE: FOUND OUT AFTERWARDS THAT MAINT LOGBOOK ENTRY WAS REQUIRED AFTER FIRST ABORT.
