Here in Manitoba--Brandon anyway, Winnipeg will be different--we're now paying $4.50 for a US gallon. The price jumped a couple weeks ago--it had been $4.07/US gal up until then.
We had been doing pretty good--prices were going up all over the country that week, but our prices held steady. I filled up at noon on the Friday 2 weeks ago and got the old price. I did notice the Co-op station was very busy at that point, cars going every which way trying to get to the pumps, and I guess some of the other drivers knew that prices had already gone up at some of the other stations. I didn't know that at the time. A half hour after I filled up, the price went up at Co-op too.
I drive a '94 F-150 and usually fill up every 100 miles--I don't let the tank get below half, or not even to half...got in that habit when I was driving my older truck that had no functional gas gauge. To avoid running out of gas I would use the trip odometer & just fill up every 150 km. So, I just continue with that habit now. Since the price increase my 100 miles of driving costs me $3+ more than it did before.
I was driving a Ford Taurus for awhile during the winter and loved the gas savings with it--it was costing me half what my truck does to drive back & forth from work. But--when the weather turned really cold that car really started sucking gas! Suddenly I wasn't saving anything at all--the car was taking $10 a day and at the time my truck would have been costing me $11-12 per day. I was surprised! Still, I wouldn't mind having a similar car to drive now--in nice weather it would save me a bundle!
