An oil-pressure warning with the engine running is different from an oil-change reminder. Pull over safely and switch off the engine. Continuing to operate with inadequate oil pressure can cause severe damage.
Follow the owner's manual before checking the oil level. A normal level does not rule out a pressure problem, and adding oil does not automatically make restarting safe. Arrange assistance if the cause is uncertain.
Tell Oxford Automotive Tire & Repair Sunbury when the warning appeared and whether there were unusual engine noises. Avoid running the engine again merely to confirm that the light returns.
