Well could be a sending unit, but it could also be something you better check out, could be oil pump? how many miles on it? could be main bearings? I have seen oil pump shafts Striped and spun inside the oil pump, you could install a oil pres gauge? that would be easiest and cheapest, is there any knocking nose when it is running
