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).
That said, changing oil more often just because is pointless. These are manufacturer designed and built indicator systems. They are not lowballing the need for new oil. I checked some dealer sites and they say to change the Camry's oil every 5,000 miles, though some say you can go 10,000 if you use synthetic oil.
