When you accelerate, your oil pressure increases. So, if you have low oil pressure, and the indicator light comes on when you take your foot of the gas (slowing down), it will go off when you step on the gas and the pressure increases. Add a quart of oil, and see if it goes away. It wont hurt to have an extra quart in there.
