exactly ! Thats why volvo provide an accurate fuel gauge :-)

"Miles to Go " is a variable depending on current and past fuel consumption and depending on how it has been driven and is being driven can drop from 100 miles to go to 10 miles to go in no time at all .

eg , you have been getting 50 mpg from your D5 so 2 gallons left when it shows 100 miles to empty .
you suddenly start driving very hard in a hilly area if you are in a hurry to get somewhere when fuel consumpion will drop to say 15 mpg , quite possible hence the reading will drop from 100 miles to go to 30 miles to go in an instant almost .

use the gauge if you want to know how much fuel is in the tank !
