i have a 1995 jeep wrangler with the 2.5, 4 cylinder, i bought it a few weeks ago, now the problem is that when i start the jeep the oil pressure read normal, but once it warmed up and i was at a stand still at idle it dropped down to 0, but once started going it would rise up to 20 pounds. so i did an oil change today and put in thicker oil, thinking that maybe the oil that was in there was just deterorated from the jeep sitting, so i put in 10w30. now when the jeep starts it reads 40 pounds and stays there for a long time but after a while it drops down to 20 pounds while at a stand still, and a while after that it drops down to zero. can somebody please help me. im not sure if it has a bad sending unit, bad oil pump, or if the rollers are bad or if it is something else
