Hey guys...I work for Diesel Power Magazine, which pretty much means that I am pro-diesel. The newer computer-controlled diesels are very clean, Ford's compound turbo F250s-350s-450s are an ultra low emissions vehicle. What diesels still offer is great reliability and power producing potential. Many street driven diesel trucks are over 1000 horsepower, and with a flick of a switch, they can be set back to stock (or close to it.) Right now the price of diesel is killing any advantage at the pump, but in my opinion diesels are still a good idea
