Oil Change Question
I just picked up an '07 Z06 and did my first oil change on it last weekend. I don't have an owner's manual, so I used the DIY thread here for guidance and put in the documented 8 quarts of oil.
After the oil change I ran the engine for a couple minutes, checked oil pressure and it looked fine. I didn't take the car on the road because it's not insured yet due to a MN winter that doesn't want to go away, so I just parked it.
Today I pulled the dipstick and there wasn't a drop of oil on it (it hadn't been started for a week). Completely dry. So I started the car and oil pressure still looked fine. After I turned it off, I pulled the dipstick and there was oil on it. I've now let the car sit for a couple hours and pulled the stick again and the oil is past full.
So I'm confused, but does this make any sense? Is there some special trick to checking oil on these cars?

OK, so I just did a search and found some information on the process for checking the oil level on a Z.
Just to be sure, is 8 quarts the correct amount of oil to put in an '07?

When checking oil, get oil temp up to operating temp, 175 at least. Turn car off, let sit 5 minutes. Then check oil. If you don't have an owners manual, you can download one for free and keep it on your computer.

just tab to Corvette, then select 2007. That will download the OM in pdf. The info is in there on all Corvettes including the specs on the Z06 and procedures for checking/changing the oil in the dry sump system
If the link doesn work, just google 2007 chevrolet corvette owners manual pdf
and pick one of the chevy sites

Run engine to around 175 degrees oil temp. Let sit for around 5 minutes, then check oil. 07 Z06 takes 8 quarts with filter change. If tank has been upgraded then 10 quarts. Also you have 2 drain plugs on the oil pan. Make sure you remove both of them to drain oil. If not then you will have a big overfill.

You can get repop owners manuals on http://www.ecklerscorvette.com/ The dealer I got my car from bought the manual from there when I asked why it didn't come with the car (shipped).
Ebay also has authentic manuals from time to time if you want that route.

From the Owners Manual, here is the process:
1. To obtain an accurate engine oil level reading,
warm up the engine to at least 175°F (80°C).
Cold oil will not give a correct oil level reading.
2. Once the engine is warm, turn off the engine.
Checking the oil while the engine is running
will result in an incorrect oil level reading.
3. Wait at least five minutes (but not more than
20 minutes) to allow oil to drain and settle in
the engine.
4. Remove the dipstick from the external engine oil
tank and clean it with a lint-free paper towel or a
cloth. Re-insert the dipstick into the external oil tank,
pushing it all the way in until it stops.
5. Remove the dipstick from the oil tank and read the
level on the cross-hatched area. Oil levels that fall
in the cross-hatched area are normal.

175?? I have not EVER seen that temp. I'm lucky to hit 160F rallying about like a lunatic. I'm also lucky to see ambient temps over 60 deg F though..... At any rate, it doesn't matter that much. How much of a tank level difference from thermal growth can one expect with 8 quarts and 100 deg oil or 175 degree oil?
