Oil and filter

[the Ferret]

If there is a Honda car dealer near you go to parts dept and buy a 14 mm crush washer off a Civic I think. Same exact part 94109-14000 and cheap at the car dealership. Although it's nice to have one on hand, I have changed my oil 10 times and used the original crush washer 9 times. Would have used it 10 times but it fell into the drain pan and I didn't feel like fishing it out so used a new one I had on hand.

You can check your old one easily by running your thumbnail across it and see if you nail catches an edge, where the crush washer was, well, crushed lol. If it's smooth all the way across, it will be fine to reuse.
