Just got a 99 s-10, 2.2, automatic with 81000 miles on it. Just after starting and still in neutral, the oil pressure was 62 psi, when put in gear and warmed up after about 10 minutes, pressure dropped to 58. When coming to a stop and idling the pressure dropped to 20. As Ii accellerate back to speed the pressure comes back to 58. Is this within tolerance? Seems like an extreme pressure variation to me. Thanks for your help.
