The first time I drained my fuel I tried using a regular funnel. Gas, I'm sorry, petrol went every where but the bucket I was trying to drain it into. The next time I drained the petrol from the tank I thought of using an old url(that's southern for oil) container as a funnel.
I don't think I spilled a single drop. Take your time and don't just pull the plug all the way out. Use the plug to regulate the flow.
Millions? I have three kids. They always get first dibs. Needless to say I'm always broke.
