Diesel fuel is only available at just over half of all retail fuel sites in the U.S, so isn't quite as easy to find for drivers not familiar with a particular area.
Finding diesel will become ever more important though as more diesel vehicles hit the market. What we need, then, is some way of finding where all those refueling stations are.
The Diesel Technology Forum can help. The site has brought together a collection of smartphone applications, map software and websites to help diesel drivers find their nearest pump, in all 50 states.
Diesel Technology Forum (DTF) executive director Allen Schaeffer said, "these fuel locator search services will show drivers diesel refueling stations in their immediate location and some will even show the best available prices.
"In addition, drivers going on vacations or trips to new areas can use these fuel locators to help plan their excursion."
Chevrolet's Cruze Diesel hit the market recently, while several other diesel vehicles are due over the next few years. Among them are 3.0-liter V-6 EcoDiesel versions of several Chrysler group models, a diesel variant of the new Mazda 6 sedan, and a host of Mercedes-Benz and BMW models. Even Nissan has a diesel on the way, thanks to a Cummins V-8 in its Titan pickup.
