Diesel rose 8.2 cents to $4.104 a gallon, the fourth straight increase and the highest price since October, while gasoline rose for an eighth week, the Department of Energy said.

Gasoline rose 7.3 cents to $3.611 a gallon and has risen 35.7 cents in eight straight weeks of increases, DOE figures showed.

Both fuels’ prices are the highest since Oct. 22, when diesel was $4.116 and gas was $3.687, according to DOE records.

The diesel increase follows last week’s 9.5-cent jump, for a combined two-week spike of 17.7 cents, the biggest such upturn in almost two years.

Trucking’s main fuel now costs 16.1 cents more at the pump than the same week last year, while gas is 8.8 cents more than a year ago.

Diesel has risen 22 cents in four weeks of increases, after falling 14 cents in seven straight previous declines.

Oil rose $1.31 on Monday to finish the trading day at $97.03 a barrel on the New York Mercantile Exchange, the highest Nymex closing price since Feb. 1, Bloomberg News reported.

Each week, DOE surveys about 350 diesel filling stations to compile a national snapshot average price.
