Significant fluid loss to the floor??!!
I fit a latex tube (the kind they use in hospitals - don't ask and I'll tell you no lies) over the bleed nipple and drain the oil into a clear bottle, preferably sterilised (no contamination of brake fluid - mineral oil). that way you don't need to spill anything on the floor.
Any hobby shop should sell Hydrocarbon compatible tubes for model aircraft engines. These will work fine.
