oil pan drain bolt size

[RONNN]

I've noticed everyone saying the oil pan drain bolt for the gen 3 SRT10 is removed using a 14mm wrench. I'm changing the oil right now and noticed my drain bolt needs a 16mm and there are no metal shavings on it either... I also noticed my drain bolt has no magnetic properties at all. Do I need to replace the drain bolt with the OEM one? Or will the one that is currently on the car be okay?

Someone switched it for sure. If you go to replace it, be aware that there are two different thread sizes used during the Gen 3 run.
