2000 jeep wrangler with 65000 miles. after the engine warms up,about 5 mins, the oil pressure gauge will hover between 0 and 20. when at a stop light the pressure will read almost 0 and the check engine light comes on. at this point the engine will run kinda rough. i just changed the oil to semi-synthetic and this has not solved the proplem. i"m using the right weight of oil. thanks for your help.
