I drove nearly 1,000 miles in 2 days and filled the tank 3 times. After the first tankful of gas I was down to 3 bars on the gas gauge. The miles to empty showed 240. I thought that is really odd because that seems high. As I left the gas station after filling up a second time my miles to empty showed 950! Now after my 4th tank of gas everything seems normal. Does anyone know what was happening to my trip computer?
