Gentlemen, planning is everything!

I always get one of these washers with the oil filter when I buy OE.
Don't know if this is a BMW thing, or just something my dealer does but there's always one in the box.
If you buy the service KIT from MotorWorks or Sherlocks or MotoBins they will send you: The Spark Plugs, the Oil & Air Filter and all the washers you need depending on model. GearBox, Sump Plug Bevel box etc. So then you would have the washer brand spanking new when you needed it - just saying.
There would appear to be a surfeit of prolixity and sesquipedalian content today please do not use a big word when a singularly un-loquacious and diminutive linguistic expression will satisfactorily accomplish the contemporary necessity
Best solution is to use a Dowty sealing washer.
Steel washer with rubber bonded to the ID so it seals against the bolt / plug head, the face of the sump etc it is going into and also the thread of the bolt.
Infallible, available in imperial and metric sizes and cheap.

....used extensively in the hydraulics industry, so capable of sealing very, very high pressures. Although under those conditions the fittings have a little more to them than meets the casual eye, in detail design, to control the deformation of the rubber.
Sealing a few inches head of oil, no problem with any old plug probably. My only reservation using it in this very light duty application might be insufficient friction generated in the metal to metal contact? Motorcycle sumps are very fragile compared to your average hydraulic pump etc.
