How much is too much engine oil?

My car consumes some oil. Not a ton... but enough that I'll add maybe half a quart between oil changes to keep the levels right. So today I checked it and it was low. I started adding in very small increments (maybe 15-20% of a quart at a time) and then checking the level. I added most of a quart, and it was still a little low. I had maybe a fifth of a quart left, and considered adding the whole thing, but then decided to take it slow and add half of what was left.

Good move. It is, however, a bit too full now. Not a lot... a bit less than halfway between the full mark and the notch. The engine isn't totally cool, but has been sitting for maybe an hour or so, so it's definitely not very warm still. Is this enough to worry about?

I would not. You can try different brands and viscosities (if under warranty, stick to the correct specs) to see if your consumption goes down if you like.

You would not worry about it?

Hmm... any recommendations? I'm pretty new to this and don't really know anything about the different ratings. I've read up on it a bit but I'm still rather confused. The car is a 2003, so definitely no warrenty... I've been running Royal Purple 5w-30, seeing as it is the only brand around here that matches what the manual says to run.

I wouldn't no, you're probably around half a quart over.

I have a 2002 and I have used M1 0W-40, 5W-40 "Turbodiesel" and Rotella T6 5W-40. That is the order from most to least consumption too. They will all work fine even year-round for you in CO but I tended to use more of the 0W-40. The T6 is not prone to use like the other two in my motor.
