Do you boys fit a new washer to the oil bolt when you change the oil? I've usually annealed mine & re-used it but last time out I had a fair leak from the bolt, tried nipping it but it was good & tight.

I've splashed out on a bag of copper sealing washers, I shall anneal & use a new one each time now I've acquired this new found generosity towards my bike.

Horrendously expensive, but these are supposedly proper crush washers.
