(Sept. 29) Diesel prices shattered records the week of Sept. 26, with the national average topping the $2 per gallon mark for the first time, according to the Department of Energy.

The national average posted on Sept. 27 was $2.012 per gallon, a 10-cent leap from the week before and 58 cents higher than the average a year ago.

California posted the highest prices, topping out at an average of $2.236 per gallon, up 8 cents from the week before. The central Atlantic region, however, had the biggest increase, with the average jumping nearly 12 cents from the previous week to $2.102 per gallon.

The increases came on the heels of soaring prices for crude oil, which topped $50 per barrel on Sept. 28 before sliding down to $49.81 the following day.

Meanwhile, Saudi Arabia, the top producer in the Organization of Petroleum Exporting Countries, announced it would step up production with an increase of 1.5 million barrels per day, bringing its production to 11 million barrels per day.

However, some experts say oil prices are beyond OPEC’s control thanks to increasing worldwide demand.
