What size o-ring is used on the EC300 oil drain plug? Looking for size and durometer, specifically for a 2010. Searched all over the forum with no luck. Thanks!

Reading through a bunch of threads here it sounds like it can be either a washer or an o-ring... for those that use an o-ring what size do you use? For reference, the crush washer size that seems to work is a 12mm ID x 18mm OD.
