The EPA mileage estimate for the 2005 Jeep Grand-Cherokee is 15 mpg in the city, 21 mpg on the highway.
is it visually leaking oil from some where? if not it is probaly blowing blue smoke out of the exhaust which means the piston rings in the engine are bad, you need to rebuild your engine or drop in a new one
