Most folks forget, or in the case of the OP, ignore the fact that since 2010 ALL diesel vehicle manufacturers have installed software to "know" and document what is being used as a fuel. Ford & GM both state in writing that the use of ANY fuel other than ULSD will, not may, WILL void the engine warranty. I guess many feel that they are rich and love to gamble, but you need to think hard about the consequences of voiding your warranty.
I would produce the documents stating that all of mexico will be ULSD by 2009 and plead ignorance.
