How quickly should the oil pressure return to normal after starting the engine?

Within a few seconds
Within a minute
Within five minutes
Within thirty seconds

The correct answer is: Within a few seconds

The oil pressure should return to normal as quickly as possible after starting the engine, as this indicates that oil is properly circulating through the engine and providing necessary lubrication. Option B, Within a minute, may be too long of a wait time and can indicate potential issues with the oil system. Options C and D, Within five minutes and Within thirty seconds respectively, are both potential times that the oil pressure should return to normal, but they are not as accurate as the answer A, Within a few seconds.
