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).
Regular oil changes (every 3000 to 7000 miles, or every 6 months if it's a vehicle that's not driven often) with the proper type of oil for your car will assure you get the maximum possible mileage and performance from your engine.
