The pods enable the boom operator to refuel two planes at once. After the boom operator establishes contact with the aircraft's fuel tank, the computer takes over. Up to 1,100 gallons of fuel flow through the boom per minute and about 470 gallons per minute through the drogue.
Car manufacturers often suggest changing oil filters every other time you have your oil changed. Most parts and oil manufacturers, however, say to replace oil filters with every oil change, which should occur every 3,000 miles or three months (whichever comes first).
So how often should you change your oil? It depends on many factors, including the way you drive, how old your engine is and where you live. Many mechanics will recommend you change your oil every 3,000 miles. Automobile manufacturers might suggest a longer interval, such as 5,000 miles. If you use special synthetic oil, you might be able to go 10,000 miles between oil changes! For most people, an oil change every 5,000 miles would probably be just fine. You might want to consider changing your oil more often, though, if you tend to drive at high speeds, have an older engine or live in an area that is particularly hot, cold or dusty.
