Recently bought a new Bosch oil filter that came with the large rubber ring for the oil filter cap and also a copper washer for the sump plug but no o rings, Iv just read that it's very important these o rings are changed regulary as if the fail pressurised oil escapes back down to the sump starving certain parts of oil leading to a major engines fail
Opions seem to vary as it seems some BMW garages don't bother changing these rings when fitting a new oil filter. Thoughts?
