Narrative:

At FL180 we received a warning for oil pressure on the #1 engine. Our aircraft limitations require reducing power to 75% nh when between 40-55 psid. We complied due to an indication of 50 psid. We prepared for a precautionary engine shutdown. The psid slowly decreased to 40 psid at which time we performed the engine shutdown checklist. We then proceeded to mco and landed without incident.
