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).
Should you change oil as often as every 3,000 miles then? Unless you want to see your mechanic every two months, a 3,000-mile oil change interval is another extreme. If you check your oil 3,000 miles after your last oil change, chances are it will still be pretty clean. Unless you race your car daily, even mineral oil can last longer than 3,000 miles. Most car manufacturers recommend 3,750 to 10,000-mile oil change intervals.
