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).
When you check the oil level, take a look at the dipstick and see if the oil is getting too dirty. Most people change their oil about every 3 thousand miles, but you can usually go longer than that if you check it.Check your owners manual to see what it says the oil change interval should be. Never go over that.
