I've wondered how much the box containers leave... The 5qt jugs work for me and I consolidate the residue into a leftover jug. Use it for top up, whatever.
We have a township surrounding a state university where only reel mowers are allowed. Now that's not bad if you have a small lawn or enjoy the excersise. The township also made it a misdemeaner to detonate a nuclear weapon within city limits. They had a local ordninance banning nuclear materials to pass through, but the State of Maryland preempted them because the local hospital deliveries of nuclear medical supplies kept get stopped and ticketed. No lie.The 2 strokes aren't legal here so it isn't really a big deal here. Actually in Santa Barbara City all gas powered lawn tools are banned.
