I drive a diesel pick up..by choice and they do get better mileage than a regular gas pick up. I paid 4.45 a gallon at my last fill up. I have really made an effort just to drive to work and back and once down town a week to get groceries. What's sad is diesel is the crappy end of the fuel chain so I would think it would be less than gas..was told it's refined less. I would love to ride my bike to work. However coming home after midnight, after 12 + hours of work, not so sure how I would fare. And it's all up hill. Not sure where our country is going with all this high priced fuel, I can only hope for the best.
