Another thing, regarding the whole "clean diesel"... not singling you out Wicked, but do you realize that over half of the semis and other guys running diesels are using Mexican diesel? Especially Southern California? U.S. diesel (more expensive) runs 15 part per million (ppm) sulfur standard. Mexican diesel is reported to be more the 300 ppm.

Anything 2006 and older will run just fine on either Mexican or U.S. diesel. However, 07-and-newer models with a DPF (Diesel Particulate Filter) won't allow it and use more fuel to burn the excess soot out of the DPF. The temp of the burnt-out soot, when it park, will leave a 2 foot wide puddle of fresh asphalt on concrete. Did I mention that all of the above contributes to smog in LA and surrounding area?

My 2003 7.3 Powerstroke coal rollin SOB is cleaner than that!!
