Flight Crew Rejected Takeoff; General Maintenance Action
Aircraft; Procedure
During the takeoff roll; just prior to rotation; the Number 2 engine oil pressure warning light illuminated. Myself and the First Officer simultaneously called reject. I immediately reduced the power levers and applied the brakes. We were able to stop the aircraft with over 3;000 FT of runway remaining. The oil quantity was low and caused illumination of the number 2 engine oil pressure warning light when the aircraft accelerated.  After exiting the runway we stopped the aircraft and monitored the aircraft systems. The 'Number 2 eng oil press' warning light was no longer illuminated and the oil pressure gauge was in the green and all other systems were normal. I then made a PA to the passengers informing them that we had to abort the takeoff because of a warning light and that we would be returning to gate. The First Officer informed the Tower of our intentions then called Operations. At the gate the passengers were deplaned and Local Contract Maintenance Personnel was called. The oil quantity was checked and found to be low. After adding the proper amount; we did an engine run-up; all engine indications were normal.
Dash 8 Captain reported receiving a low oil pressure light on Number 2 engine during takeoff roll.  Takeoff was rejected; and the problem was solved when oil was added.
