Narrative:

At approximately FL180, the filter bypass light for the #3 engine illuminated. We proceeded to the 'red tabs' and accomplished the engine oil pressure or low oil pressure/filter bypass light illuminated checklist. This directed us to accomplish the engine failure/shutdown checklist, and subsequently the 1 inoperative, in-range, approach, and landing checklists. An emergency was declared with center and emergency equipment was requested to be standing by. It was determined that it would be prudent to return to gsp. An approach and landing were made in gsp, uneventfully.
