1999 Jeep Wrangler mileage: 120,000. When I drive my Jeep on long trips, after about a hundred and twenty miles, the oil pressure gauge starts acting erratically. The Jeep runs fine but the oil pressure gauge pulsates randomly between Zero and Forty. It only does this on the highway and after about 2 hours of driving. All other gauges seem OK it's just the oil pressure. This gauge drops causes the "check gauges" light to come on.
