Oil Level Issues

Alrighty folks, got a question for ya'll.
On my 4.7L 2000 WJ:
Changed the oil and filter yesterday.
I added 6 quarts of oil and a new filter.
Cranked it, let it run a minute or two and watched untill the oil pressure came up to normal. Checked the oil and it was exactly at the "Full" mark on the dipstick.
Drove it to work today about 7 miles. It sat there for about 30 minutes and I went out and checked it. It's about 1/2" OVER the "Full" mark. What the heck?
Should I drain it some or just forget about it? I know overfilling can be bad with some engines. Anybody else had this happen to them?

The V8s should only take 5 quarts...

I hear that you can run your engine with at most a quart over without having any problems, but I wouldnt risk it. I would most definitely drain it.

That's incorrect! The WJ V8's and I6's take 6 quarts.

cj8lvr, the 30 minute wait just let some of the oil which was drawn up in the engine drain back down to the oil pan. Your seeing exactly what you should be seeing.

That's what I was thinking... 5 1/2 quarts would put it right on the money.
So drain or not to drain?

I know some drained down in that 30 minute time period, but after draining - it should read "Full" in my mind.

My main question = has anybody else seen a reading beyond the "Full" mark with 6 quarts?

Well, I'm confident in my response, however, the best thing anyone could do in this case is to look up the answer in their vehicle's owners manual. I would recommend you do this also to: 1) go to the source for the information 2) to put your mind at ease.

And yes! My jeep's oil level reads exactly as yours does (I just changed it last week!)

The manual says 6, I'm sure your 1/2 quart over won't hurt anything. If you wanted to be safe... you could just drain the 1/2 out and be done... then you'll know for sure you're all right. IMO, I'd rather be a hair ( and I do mean 1HAIR) under, than 1/2 quart over!
