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).
There are exceptions which depends on where you live and how you drive the vehicle. For those exceptions, one may get the oil change more frequently ~3-3500 miles. It doesn't hurt the car if you change the oil more frequently but that's a personal choice and will cost you more in maintenance costs.
