It's going to take a whole lot of trips around the block to heat up the oil enough to get the pressure at idle back down to 2 bar. You didn't heat it up enough to get it thin enough to drop below 3 bar. If it is overfilled though, you ought to get the excess out of there reasonably soon. You won't ruin your engine by driving it around the block with too much oil. Next time you'll know - put in six quarts and then check it and top up as needed.

I think the higher oil pressure is nothing to worry about. If you're worried about overfill, check the dip stick. My 300D runs (warm) just over or under 3 depending on rpms. AFAIK higher oil pressure is better.

It is very important that you do not run the engine with the oil level too high.. there are threads in the archives about this... but basically the deal is that if too high the crank or air moving as the crank turns can churn it and foam it.. once you have foam the oil pump can not pump it through the engine...and also the foaming causes rapid oxidation...
Get the excess oil out or else....

if your old oil was tired, the new oil will give more pressure especially at start up with the engine cold.

be sure to let it drain down for at least five minutes before checking.

seven doesnt sound that far off to me.

The book says 7, but I've found mine usually only takes 6-1/2. I just don't think it all drains out, even when it's hot.

I was wondering about just how to get all of the old oil out. I had the vehicle upon ramps so I could get under it. That meant that pretty much all of the oil in the drain pan would have emptied out of that hole but what about oil that would have been towards the back of the engine? Because the engine is not exactly level is it? It sits slightly nose high so when the fronts up on ramps then there must be some oil that is unable to drain forwards into the oil pan.

You're better off draining it when it's level, IMHO. It's pretty easy to reach under and remove the drain without ramps. I try to drain it hot to get as much as possible out, including from the oil cooler. I doubt it's possible to get 100% of the oil out, so do the best you can.
