What size is the oil drain plug on a 1993?

I've been trying to find the right size, and it seems that a 5/8 is too small, while 11/16 is too big. Is the plug metric?

13mm, in fact i think it may say it on the bolt itself!!! Good luck!!!

i always use a 9/16 and it fits on there perfectly

Thanks, I finally was able to get the drain plug off using a 5/8 socket and tapped it gently with a hammer to get it to fit perfectly on the bolt. And just using a bit of force, I managed to finally get it loose.

thats weird. It must vary because 9/16 fit tight on mine. 5/8 was too big. All that matters is that you got it off right
