However, the problem is not the dye. Off-road diesel is often lower quality than on-highway diesel. It might have different additives or formulations, which *could* lead to:
* Reduced fuel economy: The different formulation might not burn as efficiently.
* Increased emissions: It may not meet the same emissions standards as on-highway diesel, potentially leading to more pollutants.
* Potential for injector issues (long-term): While unlikely to cause immediate problems, consistent use of lower-quality fuel could contribute to injector wear and clogging over time, especially with more sensitive modern common rail systems. This is a more indirect consequence and depends on the specific differences in fuel formulations.
In short: The dye itself is harmless, but using off-road diesel instead of road-legal diesel in your Power Stroke is illegal and carries a risk of long-term performance issues due to the differences in fuel composition, not the dye itself. Stick to on-highway diesel fuel to avoid problems.
