The BP gulf spill started April 20, 2010 and was first contained July 15, 2010. Oil flowed into the Gulf of Mexico at an estimated rate of 30,000 - 60,000 barrels per day. Some oil was contained by siphoning directly from the cap, some was burned in open waters, some was "dispersed" using chemicals and some was skimmed.
The NY Times and Associated Press have been reporting a total of "94 to 184 million gallons". This estimate as of July 29th 2010 after the new temporary cap had been placed and the leak had been stopped. The final sealing of the well but pumping in drilling cement from one of the two relief wells is estimated to be completed by mid August.
840,000 to 1,700,000 US gallons is flowing into the Gulf every day.
Yes of course it spilled so many gallons of oil that it dwarfs all other oil spills.

There have been many oil spills that have leaked into water sources. See related questions.
If a pool was leaking for 12 hours and leaked out 78 gallons of water in total, then it would of leaked out 6.5 gallons every hour. This is a math problem.
