I recently purchased a used '08 torrent 3.6 litre which is getting terrible milage. I am getting approx 420 Kilometers per tank, which in my experience with other vehicles, is far from normal. I also own a '09 charger with a 3.5 L high output, and I'm getting approx 550 kilometers per tank. Within the last month I replaced a bad ignition coil, a cat converter and air filter, all of which I thought was the cause of the excessive fuel consumption. Any suggestions or is this normal??
