2003 Grand Cherokee Oil Pressure Gauge...

Hey guys,

This is probably a pretty easy question for most of you to answer but my oil pressure gauge used to sit in the middle of the gauge and now it is like one notch upward or a little more. What would cause this, just a different amount of oil that was put in from my last oil change? Is this going to a problem or no?

Thanks for the help.
Blake

My I6 is at one or two notches when there is throttle applied. So it doesn't seem like an issue. Maybe the last time the oil was changed 5w30 could have been used instead of 10w30. Or the oil level could be at the top of the safe level and before it was at the bottom of the safe level. More info on the engine would help.

That level is fine. Mine hovers around middle-middle +1 at idle and middle +1 - middle +2 under load. If I'm going back to idle after driving for a while it usually idles at middle -1. My guess is that there is a slightly different amount of oil but it is nothing to be concerned about.

Just an FYI-The oil pressure gauge is not an indication of the amount of oil that is in the crankcase, it's the amount of oil pressure produced by the oil pump. You could have a quart of oil in the engine, and the pump would still be putting out the same amount of pressure as long as oil was available.
Having said that, the oil pressure gauge could be going south, or a different viscosity/type of oil used. As the change is very nominal, no need to go into any mechanical mumbo-jumbo.
It's fine, but just keep an eye on the gauge.

Sounds normal. I have the V8 and mine sits at about 3/4 to the high side during highway cruising.
