What you're supposed to do is siphon directly from their tank to your. It's the nature of siphons that if the cars are of equal size, you'll both end up with half a tank - from each according to his ability; to each according to his need. Now, if it's a great big, guzzling SUV, you might end up draining it. He deserves it, so go for it.
