My 2003 Volvo V70 has been running out of gas... but there's still at least 4 gals of gas in the tank, the fuel gauage reads 3/8 full, and the message window says there's 140 miles to empty. But the car loses power (just like running out of gas). And, once I fill it back up, it restarts and runs great. I know there is at least 4 gals left, becuase I have an 18.5 gal tank. Sometimes the engine "feels" like it's running out of gas, and if I pay attention and get lucky, I get the gas station without the engine completely stalling.
