Narrative:

I was in cruise at 8;000 ft along my route when the right engine oil pressure gauge showed low pressure. Although the props did not loose speed and the temperature did not seem to rise; an emergency was declared and a landing was performed at the nearest airport. While in descent; the instrument was tapped with the fingers and the needle moved up some. When touch down was achieved; the needle returned to normal with the light jolt of landing. On the ground I ran the engine checked the oil and all was in normal range. The props could be feathered. It was concluded that the initial reading was an error and the journey was continued without events.
