Yes, but that assumes you removed a certain amount of oil!

In september I purchased a 2015 Z51 in Michigan and drove it home to the Pacific Northwest. I first checked after a few hundred miles and it was an inch above the full hash mark or where the OP indicates his was.

When I got home I had the oil changed but before I took it in I pulled the bridge between the air filter and the manifold and it was full of oil.

The dealer cleaned that area and the PCV lines. I told them to put in 9.0 quarts and they obliged. This put me just under halfway between the dipstick marks . After 1500 miles on the new oil change, I added 4 oz to keep it at the halfway mark.

Like I've stated before, the throttle body is located up an incline, so no oil can flow into the engine, unless of course, you tip the car up.

To put it another way. I measure the oil level on a hot engine according to GM protocol, then add or remove enough oil to put the oil level in the center, or just below center, of the dipstick hash marks. The next morning when the engine is cold, I check to see where the level is on the dipstick. Wouldn't filling to that level on a cold engine, give me the correct oil level, which would read to about midway through the hash marks when engine is hot?

I follow that logic and I would concur. Let the car sit for 3 or 4 days and note the location of the oil on the dip stick. If, when hot, the oil settles in at mid-hash I would conclude that you can fill cold if you use the ascertained "cold" dip stick level. My question is, "Do you get a reading on the dip stick after the car sits unused for 3 or 4 days (or longer)?"

If yes, then we have a cold level oil mark that we can refer to. If no, then you must check and adjust with the oil hot.

how is it we can make a damn quadratic equation out of everything?

We sure are lucky huh?

That would work if you had any indication of oil at all on the diptstick. Try it for yourself, but I think you'll find that oil will gradually drain out of the tank overnite so that there is no oil level visible anywhere on the dipstick the next morning. At least that's been my experience on two dry sump Corvettes.

If no oil on the dipstick after a 3 or 4 days "rest" then there is NO cold level that can be ascertained and the hot measurement is the only thing possible.

This summarizes the issue perfectly. Measure the oil hot, just the way the manual describes. And do it at 5 or 6 minutes after shutting the engine down -- even at 10 to 20 minutes, you'll start to see a drop in the oil level.

have a look at this video on how the dry sump works on the vette...it's quite involved...

Good stuff. Thank you.
