It's not cheaper, it costs the same to produce either type, and it was certainly not about $$$ why the newer TJ oil pressure gauges only show a mid-scale reading. In fact, the early TJs came with true/accurate oil pressure gauges but they were reprogrammed later so they only show a mid-scale reading when the oil pressure is ok.
The early TJs were being purchased in large quantities by people who had never had a vehicle with a real oil pressure gauge & they didn't understand that oil pressure drops at idle & rises up when the engine is revving. They were pestering their dealerships, claiming it was a problem & the dealers couln't convince them otherwise. The dealers forced Jeep to reprogram the oil pressure gauge to not show the normal ups & downs so the customers wouldn't be unnecessarily alarmed.
