you're making things out to be so difficult and they aren't!
It's worthless to measure what you drain out. Just drain it. You'll always have oil left in the filter and in the engine. Just drain it.
I wouldn't use this garbage in my car unless it was -20 degrees.

12. Remove the oil dipstick and wipe it off with a rag. Put it back in and take it out again. Now make sure that the level falls between both dots. If not add half a quart or so and check again. When reading the dipstick, make sure that you do not turn it upside down as it will skew the reading. Due to the nature of how thin 0W-20 oil is, it is actually quite hard to see exactly where the level is unless you are in a well lit area. The yellow line shows where my level was.
Top hole is the max full mark. Wipe it down with a rag and insert. Pull it back out and look at it without flipping the disptick upside down. Use a light if you can't see the oil. It's not that difficult. Dump around 4qts in and start the car. Look at your levels. Add a bit more and repeat till you hit the mark you're happy with. You should be able to see what is wet and not wet on the dipstick if you've wiped it with a rag no matter if it's 0-20 or whatever.
0w-16 has been out for years, and is used in some honda/toyota other manufacturers. There is nothing out of the ordinary with honda's dipstick, oil, or torque values. I think the last 3 vehicles I've had used similar dipsticks, torque values, crush washers and oil weights. That was also on various car manufacturers. They'll just throw your complaint in the trash, but if you want to waste your time give them a call.
