2006 Buick Lucerne Question: Oil pan plug size

I am trying to determine the exact size of wrench that will fit the oil pan plug on my car. One 14mm socket fits it, but a 14mm open/closed end straight wrench is too large. What is correct? -
Answer 1
Some show 13mm and some show 14mm use the boxed end as long as its snug it will be fine. -
Answer 2
Using a wrench a 13mm will fit it. -
Comment 1
13mm seems to fit pretty snugly. No room for a drive though, just use a box wrench. -
