I was searching for something on this exact topic and found this thread. I can not get an accurate reading on this dipstick cold or at operating temperature. I changed out the factory fill on my Sportwagen this past weekend. I check my oil level every week and using the procedure in the manual, the oil level was just over 3/4 in the hash mark area of the dipstick the day before the change. When I extracted the oil, I got out just about 6.2 Quarts from the engine and filter, and proceeded to fill up again while checking the level and put in just under 6 quarts.
Checked yesterday and cold it shows at the top of the hash mark area and operating temp just above the curved hash mark area or more exactly, in the "B" area shown in the manual. (Picture below) Checking last night and this morning in my garage again, I can't get an accurate reading as its different back to back, cold and hot. It's annoying because even though I put back in less oil than I took out, it's showing I'm right before the overfill area for some reason.
It's over the hash mark area but at least it's still technically not an overfill according to the manual. Lol
