In the absence of any other explanation, I guess I could go old school with a locking gas cap!

I cant think of another logical possibility. If a leak were bad enough to noticeably drain your tank, you would definitely smell it. If the fuel system was dumping that much fuel in while it was running, it would smoke and run horribly, if at all.

I think the locking gas cap would be a good step, and maybe a note that reads "You're on hidden camera ****face !!" and place it in there oriented in a certain way so you can tell if the door has been opened.

I can imagine gas thieves hitting the same car over and over, especially if its parked in the same position regularly, always has gas, and they take only so much where they think you wont notice.
