Narrative:

Shortly after level off the so observed the oil quantity in #2 engine was decreasing at a rate quicker than normal consumption. During slightly over 1 hour flight time, oil quantity in #2 engine decreased from 3.25 gallons (as noted before engine start) to 2 gallons by the time we landed at slc. Upon parking the aircraft, we advised the mechanic of the oil quantity situation in #2 engine. After we deplaned, the mechanic met us at the gate house and advised us that the oil cap cover on #2 engine was loose. I had this happen once before, and the oil loss necessitated a shutdown of #2 engine (same reason). We were fortunate that the flight was not of longer duration and the loss of oil quantity was not more rapid.

Title: SO OF ACR LGT NOTICED OIL CONSUMPTION HIGHER THAN NORMAL SHORTLY AFTER TKOF. ACFT CONTINUED TO DEST WHERE OIL CAP WAS FOUND TO BE LOOSE.

Narrative: SHORTLY AFTER LEVEL OFF THE SO OBSERVED THE OIL QUANTITY IN #2 ENG WAS DECREASING AT A RATE QUICKER THAN NORMAL CONSUMPTION. DURING SLIGHTLY OVER 1 HR FLT TIME, OIL QUANTITY IN #2 ENG DECREASED FROM 3.25 GALLONS (AS NOTED BEFORE ENG START) TO 2 GALLONS BY THE TIME WE LANDED AT SLC. UPON PARKING THE ACFT, WE ADVISED THE MECH OF THE OIL QUANTITY SITUATION IN #2 ENG. AFTER WE DEPLANED, THE MECH MET US AT THE GATE HOUSE AND ADVISED US THAT THE OIL CAP COVER ON #2 ENG WAS LOOSE. I HAD THIS HAPPEN ONCE BEFORE, AND THE OIL LOSS NECESSITATED A SHUTDOWN OF #2 ENG (SAME REASON). WE WERE FORTUNATE THAT THE FLT WAS NOT OF LONGER DURATION AND THE LOSS OF OIL QUANTITY WAS NOT MORE RAPID.
