I can see ther being a whole slew of folks that have diesel powerd equipment that will need additived to operate, Our towns powerplant in currently useing a sulpher bearing diesel fuel.
Current aviation Jet fuel has no sulpher in it because it would mess up the jet engines turbine blades.
Private farmers and truckers will have a hard time switching over, big companies that can afford to make the switch will survive for shure.
Interesting note on increase of imported used farm tractors and farm trucks from Japan, there government taxes expotentially old equipment over five years old, they maintain current technology on there farms and roads by taxing dirty emissions rigs out of existance.
they been cashing in on there old rigs by exporting ther rigs that dont make current emissions standards to the rest the world.
