Pullin with the dreaded PACCAR Mx13

The 485 spec doesn't look altogether that impressive on either chart, but it beats the crap out of the 405s I was driving as a company driver. There being 455MTs could explain why some of the 455s pulled away from the higher rated trucks.

I asked about rerating the engine to 510 1850 and they said I'd need different turbo, injectors, etc. Does anybody know if that's true?

I'm also kinda curious about the 455MT/1650/1850. It looks like that spec has higher horses and torque in most situations than the 485 1650 does. The 485 spec on my truck only has more power above 1450rpm to about 1850. The 510 is generally higher but the 455MT 16/1850 even has places where it beats the 510.

In any case, I'll be doing dry van/reefer for now. Biodiesel is something I definitely need to avoid. Other than Minnesota, what states are to be avoided for fueling for avoiding biodiesel?

I'll mostly be running the middle of the midwest. Do Kansas, Nebraska, Oklahoma, Texas have much tomfoolery afoot with biodiesel? I'm looking to use the cheapest winterized diesel I can find since I'm based out of SD.

I'm using mudflap. It defeats the discounts I get from the company fuel card by like 30 cents/gallon which is kinda crazy
