I doubt that's it, but given the engine runs colder during this time of year and the rings haven't completely sealed, I guess it's always possible. When I change my oil I'll get a sample to get tested and see what happens. However, I didn't really smell any gasoline in the oil.
I've always worked on all my cars and have always done most maintenance. I have never owned a dry sump car so this was me to me. I did however follow everything the owners manual says. Are you saying I did something wrong?
No. There is usually a 20-30* swing in oil and coolant temp.
Like I implied the car is fine it’s the owner that doesn’t know how to check it’s oil.
So you're saying if I just warm the coolant to 175 the oil will now be low? I don't buy it. I'll try it out, but I think you're wrong. Regardless of where the temp was the oil level was almost always in the same spot. I'm always willing to learn. You don't know me, so don't judge so harshly.
So here's what I did. I started from could and let it idle. As coolant temp Rose I took a few measurements. Honestly between 165 and 174 the level did not change much. I could not get it to 175 but I figure 1 degree shouldn't make a difference. Anyone think otherwise? The oil was at the top of the dipstick, which leads me to believe that I was correct in removing the oil earlier.
Also, you'll now the picture of the warning saying car will shut off. Apparently if not put in a gear it'll shut down after 10 min. Regardless of how you start.

Id listen to him, he sells GM parts and has been doing oil changes for years. He knows his stuff. Aint that right Cjunkie?

Look, I don't doubt he's knowledgeable, but I'm not an idiot. The point between oil and and coolant temp what warning up a car still doesn't make sense to me. The manual says coolant at a minimum of 175. The coolant always heats up faster than the oil when warming up a car, so if oil is at 175 it only stands to reason that you've met the 175 coolant temp. Anyway, no point arguing. I appreciate the help on this topic and given I'll be doing an oil change soon the current oil level, which is almost spot on isn't important anymore.
I'm pissed. My car was about 1 quart too high. I suggest anyone with a 2025 Z06 check their oil level. I sucked it out and am now exactly at the top mark. So I did 455 miles with an extra quart. I'm assuming no damage was done. I want to inform GM as they shouldn't be screwing up the most basic items.
By the way, idling for about 10 min, the car will shut down. Scared the hell out of me but started right back up.
My 2025 was overfilled by a quart as well. I sucked it out thru the dipstick. Crazy it would come overfilled like that. I got lucky and caught it with 50 miles on it. Overall with dry sump I wouldn’t worry as much but still wth. What was shocking was how dark the 5-50 oil is. I thought it smelled like gas a bit but could be from idle and new motor break in or simple reality… not like I smell engine oil often.

I'm still not convinced GM isn't slightly overfilling these at the factory intentionally. Think about it, it's just oil in a tank, not in an oil pan. So the crank isn't hitting the oil and it's a brand new engine that may have some oil consumption during break in. Would you rather end up being low on oil (because 90% of the owners probably don't ever check it ), or have some safety built in with plenty. There obviously can be way too much, but they also may have plenty of tank volume to accept more than what shows on the dipstick. Just something to consider, because almost everyone that checks theirs has an overfill.

Agree, at this point I'm not really overly concerned. I had my moment of panic but rectified it and learned a little in the process. I'll change my oil at 1k or less depending when the season ends for me. I am pretty religious about checking oil in my cars if warranted and given the manual said that oil consumption may be higher during break in got me looking. Live and learn.
