It is well known by Mazda CX 5 owners that in order to get the dipstick to read at the top mark after an oil and filter change on the 2.5L Turbo engine requires 5.5 quarts and not the 5,1 quarts that are published in the owners manual. I don't want to start out almost a half quart low even though that is probably OK for the engine.

I just changed the oil in my new to me 2020 Wrangler with the 3.6. The book says, as well as the interwebs, that I only need 5 quarts. So, I put in five quarts. I put what was in my drain pan into the new oil bottle, and it equaled 5 quarts. I did not pull the stick before doing the drain.
The stick was at the full mark. Then I briefly ran the engine, shut it off, and waited overnight and a day to pull the stick again (I don't drive it to work). The stick was at the bottom of the cross hatch. After lots of 2nd guessing and internet reading, I added a 6th quart and the oil is now at the top of the cross hatch, where it should be. I have not started it since, but it is eating at me that I may have one quart too much.
Winter weather is moving it, so it may be awhile before I drive it, but I think I will leave that 6th quart in for now. When did oil changes become so difficult?

It annoys me that the listed capacity for my Corvette is 7 quarts but when I did the very first oil change I found out that only 6 quarts comes out. So every oil change I am only adding 6 quarts of new oil and the dipstick shows full. But how does GM come up with 7 quarts? Are the dealers actually putting in 7 quarts when they do a wet sump C7 oil change?
(FWIW, the dry sump equipped C7s specify 10 quarts in the manual and those that do their own changes have found that number to be accurate)

I always go by the dipstick or sight glass (ie, motorcycles). I consider the volume called out in OMs is just to get you close and gives an idea how much oil to have before changing the oil and filter.
I go by the dipstick and ignore the documentation
My Generac RG027 says 5 Quarts, but from empty 5 quarts doesn't even get you on the dipstick!

I had to drain a quart. It’s very strange that the initial reading was a quart low. I’ve never had a car do that. I can understand why some dealers are putting 6 quarts in the JL 3.6l
When I was young and of sound mind and body, I was very particular about the oil level and quantity. Now that I've become Grandpa Simpson, my car gets, like 4WD said, "a jug".

How much space is between the oil and the crankshaft typically?
Quite a bit, and there's typically a windage tray between the oil and the crankshaft.
