1999 Dodge Durango Q&A
1999 Dodge Durango Question: Why does my truck use a lot of gas?
1999 Dodge truck DO use a lot of gas, typically 13-18mpg. They are gas hogs, however you fuel gauge may be intermittent or not reading correctly. Keep track of how many gallons of fuel need to fill the tank in relation to the fuel gauge position. This will give you some idea if the gauge is not reading correctly. Also, Winterized fuel will give you poor gas mileage. - Johnny Mopar
