Oil drain plug

#1
Can anyone tell me if the drain plug on a Honda gc160 is metric thread or standard pipe thread
Would like to extend it a bit. Always like to have the right parts before I start
Thanks in advance

At the very least you can take it out and take it to Lowes or the hardware store and check it there. My guess would be HONDA = JAPAN = METRIC..... Irregaurdless of where it is built.
