Diesel prices look like they have been riding a roller coaster this year- after a long climb to the top, prices dove down during the winter, then bumped up slightly, back down, and are now on an upward climb again.

This week, prices are at $2.854 a gallon. That’s up .043 cents from last week, and .10 cents from April 13, when prices hit their last low.

Prices are still more than a dollar lower than they were last year.
