fuel economy

my truck seems to be getting the worst fuel economy i used to get about 400 k per small front tank then it fell to maybe 200 k per tank now that my cross over is fixed it has seemed to pick up a bit more but is there anything else that can be killing it ? i just put a k&N filter on it .... thanx

If you are at dawson creek you are buying winter blended fuel it will always lose fuel mileage compared to #2 power too, but it might not be as noticable if you are running empty.

Oh, tis noticeable alright, I lost about 2mpg on average with this winter stuff. On the other hand it's nice to not really worry about gelling in the cold...
