If you buy bar oil in gallon jugs, use your bar-tool to poke a hole in the foil cover and use it like a squeeze bottle instead of tearing the whole thing off! No more oil floods on the saw, or if the jug gets knocked over, far less mess:
Got one along these lines (no pic right now but if I remember I'll take one at work tomorrow):
When you tear the foil off start at the back and leave it attached about 25% at the front, every pour it'll act like a built in funnel as well as stopping the drips from going down the side of the jug. Then just flip it back in place when you're done pouring and screw the lid back on.
