diesel fuel average cost
Projected Price Trends. Crude oil prices are expected to average $43 per barrel in 2009 and $55 per barrel in 2010. The price of diesel fuel, which averaged $2.45 per gallon in December 2008, is projected to average $2.27 in 2009. Price trends will be largely dictated by the duration and depth of the worldwide economic downturn, the timing and pace of recovery, and actual production by OPEC refineries.
