High-sulfur dyed diesel remains unapproved for use on US roads unless the Environmental Protection Agency formally changes its position in writing. That leaves a central obstacle for any plan associated with President Trump to expand its road use.
As Jalopnik reports, the fuel industry itself doubts the proposal can work under the current regulatory stance. A political announcement alone would not establish permission for motorists to use the fuel on public roads.
The distinction matters because fuel rules are enforced through formal standards, not informal signals. Until a written EPA change is in place, high-sulfur dyed diesel cannot be regarded as an approved road fuel in the United States.
For drivers in Montenegro, the US debate is a useful reminder that fuel legality depends on the jurisdiction and the specific product. Motorists should rely on the applicable local rules and approved fuel specifications rather than assumptions drawn from policy debates abroad.
