What should the oil pressure be on a 1997 jeep Cherokee?

The exact oil pressure specification for a 1997 Jeep Cherokee depends on the engine it has (4.0L straight-6 or a different engine). There isn't a single number.

However, a general guideline is that at idle, the oil pressure should be at least 10-15 PSI. It should increase to 30-50 PSI or more at higher RPMs (around 2000 RPM). These are rough estimates.

To find the precise specifications, you need to consult your owner's manual. This manual will give you the correct oil pressure readings for your specific Jeep Cherokee's engine and operating conditions (temperature, etc.). It's the most reliable source of information.

If you don't have the owner's manual, you might be able to find a digital version online by searching for "[Your Engine Size] Jeep Cherokee 1997 Owner's Manual". Replacing the "[Your Engine Size]" with the correct size for your vehicle.
