Diesel prices around the nation gained another 2.1 cents this week, marking the 11th straight increase in a row according to the Department of Energy's pricing survey.

The national average price on Monday was $3.534 a gallon, nearly 78 cents a gallon higher that it was a year ago -- and the highest it has been since October 2008.

Gasoline prices showed a little more stability, rising just 0.8 cents to $3.14 a gallon.

Oil prices, on the other hand, showed a marked decline on North American markets on Monday prompted by rising supply, tepid demand and the departure of former Egyptian dictator, Hosni Mubarek. West Texas Intermediate crude fell 77 cents, ending the day at $84.81 on the New York Mercantile Exchange -- its lowest level in three months.

It was a different story in London. Brent crude rose $2.14 to $103.08 a barrel on the ICE Futures exchange, where concern remains that unrest in several Middle East countries may still disrupt oil supplies in the region. Brent is used to price oil in Asia and in Europe.
