Every three weeks? Dang, lucky.I fill up about every three weeks. Last time I paid $5 a gallon, but prevailing prices were $5.40ish. That was about two weeks ago.
This morning I saw $6.899 at a Sunoco in town. Yikes.
I have to fill every week, but I guess I put on about 190 kms a day for work. My employer does pay some for mileage, very thankful for that right now.
