The U.S. average retail price of diesel rose 4.2 cents to $3.048 a gallon, according to the Department of Energy, as crude prices dropped amid pressure from President Donald Trump to keep the price of oil low.
The national average price of diesel is 4.1 cents higher than it was a year ago, when the price was $3.007, DOE said after its Feb. 25 survey of fueling stations.
Average prices for diesel rose in every region, with the largest increase in the Midwest after a 6.5-cent jump to $2.969 a gallon.
Additionally, the U.S. regular gasoline average price rose 7.3 cents to $2.39 a gallon, 15.8 cents lower than a year ago, DOE’s Energy Information Administration said.
Crude futures on the New York Mercantile Exchange closed Feb. 25 at $55.16 per barrel compared with $56.09 on Feb. 18. It was crude’s first drop in nine sessions.
A tweet from President Trump coincided with the decline.
Meanwhile, Cumberland International Trucks is demonstrating that a properly spec’ed truck already can come close to 10 miles per gallon.
Its latest spec option for its C10 Class 8 is TruckWings from XStream Trucking Inc.
TruckWings works by automatically deploying panels from the back of the cab to cover the tractor-trailer gap when a truck is at highway speeds, which boosts fuel economy by 4%, according to Redwood City, Calif.-based XStream. The panels then auto-retract at slow speed, allowing for trailer clearance in turns.
The gap is required for turning, but a literal drag on the vehicle the more than 90% of the time that it’s driving. Using TruckWings means customers can improve the efficiency of their routes, “regardless of the trailer they may be hauling,” said Patrick Mendenhall, fleet sales manager for Cumberland.
“Technology continues to evolve faster than ever and as Cumberland strives to be the industry leaders in fuel economy, it is our job to stay on top of the latest technology for our customers,” he said.
Since 2013, the Nashville truck dealership has been offering prospective customers the chance to drive an over-the-road tractor for an extended period. Initially the truck offered was a ProStar, now it’s an LT model powered by a Cummins X15 engine and Eaton 10-speed transmission, with several readily available aerodynamic features, plus a collision avoidance system and auxiliary power unit.
A fleet test of the C10 truck in December covered 4,891 miles and achieved an overall fuel efficiency of 9.30 miles per gallon, increasing to 9.71 mpg in top gear, in which the truck traveled for 93% of the distance, according to an engine control module summary of the trip.
The industry’s generally accepted average fuel mileage is 6.5 mpg.
