The American Petroleum Institute has licensed about 400 oil marketers to sell the new CK-4 diesel engine oil since Dec. 1 and more than 60 to sell its slightly lower-viscosity relative, FA-4. These new oils, collectively labeled PC-11 during development and testing, promise fuel savings and, in most applications, longer oil-change intervals.

Ancra International introduced its Retract-A-Roll 3 addition to its cargo handling systems.

Equipment manufacturers and diversified suppliers reported mostly stronger fourth-quarter results.

Fleets that have adopted the latest in active safety technologies, such as adaptive cruise and electronic stability control and, most recently, collision mitigation, report that there is little additional maintenance associated with these complex electronic systems on trucks.

Equipment and component manufacturers are using new designs and materials such as aluminum to remove weight from Class 8 tractors, which helps fleets increase payload and maximize fuel efficiency.

While it’s no secret trucking fleets have been frustrated in recent years when it comes to getting problems with their rigs diagnosed and repaired in a timely manner, truck dealers say they are working harder than ever to improve service and uptime for their customers. But, they say, fleets need to step up to the plate as well.
