Vehicles that run on diesel fuel are susceptible in frigid temperatures, because the paraffin in the fuel hardens, coating the engine filter, and preventing fuel from flowing.

In Franklin County, Pa., diesel-powered trucks and snowplows were given a fuel additive as well as the winter blend of thinner diesel fuel, reports Public Opinion News.

"Trucks coming from the south that don't have treated diesel fuel could have a problem," said David Rock, the Pennsylvania Department of Transportation's manager for Franklin County.

The Missouri Department of Transportation reported a few trucks out of service due to fuel gelling in Springfield, reports KSMU. The agency's Gary Shisler told KSMU that diesel fuel had gelled in storage tanks at the MoDOT garage, which has 300 trucks and snowplows that run on diesel fuel.

In Dent County, Mo., cold temperatures caused fuel gelling in county graders and other road equipment. The computers in the graders also failed to work, reports the Salem News.
