Gasoline Problem (Posted on 2003-04-11) Difficulty: 3 of 5
A man's car runs out of gasoline. His car tank holds exactly 13 gallons. He has three empty unmarked containers which can hold 3 gallons, 6 gallons, and 11 gallons. Using only these containers at the gas station, how can the man bring back exactly 13 gallons?

(He is not allowed to buy over 13 gallons and dispose of the extra.)

How can you people not figure this out? I did it in in less than 30 seconds. And I've seen the puzzles you post, you're not stupid. You are driving me crazy with your blindness!!!
