For what it is worth, I think the premium is probably for high-performance diesel cars and not worth the extra money for your bog-standard pickup trucks. My Ford Ranger (2009) has always run on the standard Diesel, now called Diesel - B7, and I have never had problems with the injectors or other parts of the fuel system. The pickup still starts easily (first turn of the key) and runs smoothly with more than 150,000 kilometers on the clock.
