Narrative:

#1 engine oil quantity went to 0 about 1 1/2 hours from hayden, co, our destination. The checklist says to monitor oil pressure and oil temperature. If they remain normal then continue normal flight with engine running. As we entered the VFR traffic pattern at hdn the oil pressure for #1 engine dropped below recommended value and oil temperature began to rise. I shut down #1 engine and after running the 1 engine inoperative checklist, we made a normal landing at hdn. We could not get ahold of unicom to call out precautionary emergency equipment for standby. The FAA just happened to be doing a ramp check that day and became quite involved in the matter. The culprit in the shutdown was the fact that when cleveland maintenance added oil in cle, they apparently forgot to put the oil cap back on and therefore as we flew along, all the oil got sucked out. 18 quarts of oil were added in hdn and we then completed the engine inspection as is required and we went on to denver, co.
