Today I realized that my oil pressure was dropping when I let off the gas, which never happened before. Every day before today my oil pressure would be at between 42 and 45 on the gauge (I don't know the units). But when I came up to a stop sign today and stopped I watched my oil pressure drop to 30 and may have gone more but I had to go, and when I did it went right back up to the 40's region. Just wondering what this could be, If you need anymore info just please post. (The jeep just recently hit 107k miles and i was wondering if it was just the oil pressure gauge or the oil pump)
