After two weeks of rising prices, diesel last week fell nine-tenths of a cent to an average retail price of $2.951, according to the U.S. Energy Information Administration.
The mild retreat is consistent with an up and down trend for crude oil futures over the past month and an even longer period of stability from May 4 to Aug. 2, when oil futures have traded between $70 and $80 per barrel.

The average price on the West Coast inched up just one-tenth of a cent to $3.121 per gallon, held down by a 1.1 cent drop in California to $3.139 per gallon. Prices on the West Coast as a whole and in California were the highest in the nation.
The deepest decline was a slip of 1.6 cents in the Midwest to $2.928 per gallon.
