The oil pressure for a 1991 Isuzu Trooper with a V6 engine typically ranges between 10 to 50 psi (pounds per square inch) when the engine is at normal operating temperature. At idle, the oil pressure might be on the lower end of that range, while higher RPMs should show pressure closer to the upper limit. It's essential to consult the vehicle's service manual for specific specifications and ensure proper oil levels and viscosity are maintained.
