Narrative:
While en route from cle to ewr observed #1 engine oil decreasing. All engine gauges indicated normal. At about 1 gallons of engine oil on gauge, reduced thrust to idle on #1 engine. This slowed the loss of engine oil considerably and was able to continue with flight. Again all gauges indicated normal in both pressure and temperature. Called maintenance control and advised them and they said as long as there was pressure and temperature. Was normal to continue. Flight continued and landed without further problem.

Title: LGT FLC NOTICED ENG OIL QUANTITY DECREASING AT CRUISE. NO OTHER ENG INDICATIONS.
Narrative: WHILE ENRTE FROM CLE TO EWR OBSERVED #1 ENG OIL DECREASING. ALL ENG GAUGES INDICATED NORMAL. AT ABOUT 1 GALLONS OF ENG OIL ON GAUGE, REDUCED THRUST TO IDLE ON #1 ENG. THIS SLOWED THE LOSS OF ENG OIL CONSIDERABLY AND WAS ABLE TO CONTINUE WITH FLT. AGAIN ALL GAUGES INDICATED NORMAL IN BOTH PRESSURE AND TEMP. CALLED MAINT CTL AND ADVISED THEM AND THEY SAID AS LONG AS THERE WAS PRESSURE AND TEMP. WAS NORMAL TO CONTINUE. FLT CONTINUED AND LANDED WITHOUT FURTHER PROB.
