Captain reports a master warning left engine oil press message appeared during descent; but quickly extinguished. The crj quick reference handbook (QRH) said to pull throttle to idle. Oil pressure fluctuated in low 30's. Mechanic meeting aircraft said engine was three quarts low and recent changes in maintenance intervals had been causing similar incidents.

Narrative:
In descent we received a master warning left engine oil press message; which quickly extinguished. We looked over the QRH (quick reference handbook); and the first step said to pull the engine [throttle] to idle and see the oil pressure readout. We were in the descent so it was easy to do that. It read above 25 psi; but it was in the low 30's and fluctuating. Since the message extinguished and the indications were above our limitations; we continued and landed normally. At the airport we made a logbook entry; and the mechanic came out to inspect it.the mechanic meeting the airplane told us that the engine was three quarts low on oil; and said that a recent change to the maintenance intervals has caused a lot of these incidents lately.
