This is always less than desirable.If the bearings and such are loose enough to allow this, there is too much room there. If the oil pump is worn so that, through internal leakage, it cannot keep up with what the engine requires at idle under normal condition, then when adverse conditions arrive you could suffer oil-starvation damage.

The easiest fix is to replace the oil pump with a high volume oil pump. All that requires is getting the oild pan off. Then you will know that you have a good pump, and without tearing the entire engine apart you can meet the oil needs a loose engine presents. Any excess volume will be spent by the pressure relief valve.

2004 Dodge Intrepid "jumps" occasionally when braking?

if your car has the 2.7 litre you have to change the oil every 5oookm or 3000 miles and use the exact grade as per the book.
the 2.7 has small oil galleries.
you have low oil pressure and or idle speed.check the rpm and it should be 700 unloaded at warm temp.if the iac controller is bad and there is low idle,really low rpm could trigger the oil light to come on and the transmission vacuum controls will be causing strange behavior.
