How do I Completely Drain all of the oil?

[dave]

I plan to change over to a 100% synthetic motor oil soon, and I would like to completely drain all of the existing engine oil first. (2014 Deluxe). The owner's manual states that you need 4.1 U.S. quarts for an oil and filter change, and 5.2 U.S. quarts "after disassembly". This means that there must be 1.1 quarts of oil remaining somewhere (oil cooler and oil cooler lines?). Any suggestions on how to drain this remaining 1.1 quarts of used engine oil without disassembling my engine?

Thank you.
