When I initiallyy picked up my vehicle used in Summer 2009, my full tank of gas read approximately 615km+ and I would usually get about 500+km on a full tank.

I noticed over the last 2 months, my full tank of gas reads under 500km and in retrospect only getting about 400km on a full tank.

Any ideas? Greatly appreciate the help.

:) Yes, Kitchener/Waterloo, Canada. We've been averaging around -5 degrees for the last little while.

I was guessing the weather/climate might have something to do with it as the car still runs fine. But shouldn't the tank still fill up to the same capacity I was getting before and only get less than satisfactory gas mileage?

I also don't think I have any frozen gas in the tank which might be occupying some space.I hope.
