The oil pressure gauge in my 2000 Jeep Grand Cherokee v8 4.7L fluctuates as I use the accelerator. It sits around 0psi anytime I am under 30mph and only goes as high as 40-50psi when on the highway. The "check gauges" light always comes on but since fluctuates like a speedometer would when you change speeds, it goes off all the time. Please help!
