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).
The owners manual is the best place to start. The first oil change should be done after about a 1000 miles then every 3-5000 miles. Average oil change should happen between 3-5K miles. So if you get an oil change every 4k miles, then you would have gotten 5 oil changes after 20K miles.
