Old perceptions of diesel and hard starting still scare people and mainly the EPA who has [bleep] diesels over here so bad with all the emissions bs they force manufactures to comply with. How much of the US typically sees below 0 temps for several months out of the year and you force manufactures to use UREA basically which freezes around 10-12 degrees. There are a lot of issues with various emissions equipment on diesels these days and it's mostly in colder climates.

Add all that up with what they've done to the price of diesel and it's amazing we even have any options.
