The oil pressure for a 1997 Jeep Wrangler with a 2.5-liter 4-cylinder engine typically ranges between 25 to 65 psi when the engine is running at normal operating temperature. At idle, the oil pressure should remain above 10 psi. If the oil pressure falls significantly below these levels, it may indicate a problem with the oil pump, oil level, or engine wear. Always refer to the vehicle’s service manual for specific guidelines and troubleshooting.
