i have a specialized vocabulary i use for times like that!!!!A slot across? That might be what I started doing after I lubed up the outside of the saw a couple of times. I just peel the foil back maybe a little less than 1/5th of the way then squeeze the bottle to force the oil out. When the oil level reaches the neck of the tank stop squeezing and the flow stops virtually instantly thanks to the negative (relative) pressure in the bottle.
