A spot check of truck dealers and engine compaines in the last few days has shown that the cold weather is taking its toll on utilization again this winter. Trucks of all year models are gelling up and creating backups at repair locations all across the north, from Maine to Montana. It's hard to determine how many of the gelled up trucks are the newer 07 models at this point.
Service departments are suggesting that truck operators use a fuel additive and carry an extra fuel filter, as well as plug in the block heater when parked. I would have to think that most fleets that operate in cold environments are already doing this. The real question is how much of the gelling is due to ULSD and the lack of effective anti-gelling products. It looks like another winter of unknown results is upon us.
