Ok, I'm dumb and I forgot about my drain plug washer when I bought my stuff for an oil change... Do I need to replace this every time? Never changed the oil on my civic since I've had it (only been a couple months...) Thanks for answering my dumb question, a simple yes or no will do!

 

I actually went about 40k miles on my stock washer untill i changed it. I had no problems with leaking and everything.
Dont worry it will be fine

 

k thanks thats all i needed to know!
