Cold oil check

So....
You checked it under inappropriate conditions and you're asking for advice on how to interpret it? Start the car, heat it up and check it the right way.
Come on buddy.

Yes. You must check engine oil w/dry sump tank after oil reaches at least 175 & then wait 5-10 after shutting down to check oil level. It only has to be "between" the hash marks. Too many folks want it right at the top hole & you are asking for possible problems if you misjudge & overfill. Too much is worse than "low" again between the hash marks/holes. My '16 Z has a info plastic tag right on the fill cap. I suppose too many dealer techs weren't familiar with this tank & over-serviced. Happened twice on my '14 Z51 Stingray & once at 500 miles change on this one even tho I brought it up to service mgr. before service was done. Always check at dealer after oil is warm & shut down & check 5-10 later before you leave just in case. Too late if you drive it for awhile & have engine damage. They will probably blame you. If you pull the stick when cold it may not even register on it or will show very low. When mine was over full, I simply used clear plastic tubing 1/2" dia. snaked it down filler hole hung it down outside of fender (make sure outside tube opening is below opening of tube inside of tank or you won't get it to continue to draw when you put into your container to catch fluid). Simply suck on it hard & watch the fluid, when it gets close to your lips-stop sucking (unless you're partial to taste of oil! I use large measuring cup to see how much I'm removing.

I'm not being a smart ***. It just doesn't make sense if the manufacturer tells you how to do something so you instead try to do it another way.
That being said, why can't they just make two recommended levels for the oil? X when hot and Y when cold. Just about every other reservoir on the car has a hot and cold level.

When full the system takes 9.8 quarts of oil. That will put oil on the dipstick right at the top hole. If you are going to track the car GM recommends adding a half quart taking the amount of oil to 10.3 quarts. That will place the the point on the dipstick where you see oil about a quarter inch above the top dot.
Never checked it hot then let it cool to see where it might lie with cold oil.

Just be thankful we still have dipsticks. I have two cars where you have to ask the computer, and 99% of the time the "Conditions are not correct". It's got to be a certain temp, angle, amount of time since running, and so on.

Because it will just sit idling or you'll be depriving yourself of the fun of driving?

The oil dipstick only reads the level of the oil in the reservoir, not BOTH the level of oil in the reservoir AND the oil pan.
Thus, it is important to check the oil level before some of the oil in the reservoir leaks through the oil pump into the oil pan.

DO NOT run the car on the street if there is over 9.8 quarts of oil in the engine.

There is some merit in having a way to check the oil cold. Otherwise, if you receive a car that has an uncertain amount of oil in it, your only option is to drain it refill it and then start it. Otherwise you could risk damaging the engine if it's an overfill or underfill situation.

Best to check the oil level after 5 minutes and before 7 minutes, around 6 minutes as by much later than 7 and certainly by 10 minutes the oil is already running back into the engine pan. If one will carefully measure in the 9.8qts. at their next oil change, then run engine to proper temperature, check oil level at 5 to 6 minutes after shutting the engine down, and carefully notating where the level is between the hash marks it should be at that same place on the dip stick every time one checks the oil so long as they follow the same procedure each time.
Remember, GM suggests that one checks their oil level while refueling at the gas station and I believe they recommend doing it every time you stop for gas!

Some of you act like this is the first dry sump car ever produced. I used to own a dry sump Aprilia Supermoto bike....now THAT thing was a bitch to check and change the oil.

The efforts are worth the rewards. Every serious race car has it. Use it, love it, embrace it!

One thing for sure the consensus that the oil level can only be checked after the engine has run and is warm, like when you fill up with fuel.

A buddy of mine "hardly checked it" on his, and it self destructed quickly
