Ed, this is a couple of questions and not a challenge...
Off hand how many different diesel rig owners with particulate filters so you recollect talking to?
Has anyone you ever talked with given forth compelling evidence that having driven AT LEAST 20,000 miles in mainland Mexico with their rig, that they had for some reason had their rig into a dealer and had a comprehensive code readout of the ECU performed?
Opinions run rampant, fireside tales sometimes take on a life of their own and curiosity overwhelms me.
Petroleos Mexicanos MUST by federal Mexican law, provide ULSD to Mexico, the city before anyone else in the country gets regular diesel replaced. NO ULSD is manufactured in Mexico. It all comes from the Shell Oil PEMEX joint venture refinery in Deer Park Texas.
PEMEX is changing process units in Salina Cruz Oaxaca and Salamanca to provide UBA premium gasoline as an alternative to PEMEX premium red pump which currently is produced in the USA as well.
Providing brand new SULFUR PLANTS AND TREATERS to existing refineries is a HUGE job. It involves using HUNDREDS OF TONS of Sulfuric acid and caustic soda, yearly. A "Coker" plant. Thinking Petroleos Mexicanos is on the verge of introducing Mexican UBA diesel anywhere in Mexico is wishful thinking. When Mexico (the city) gets UBA from a Mexican refinery, the shouting, the fireworks, the hyperbole will be heard all the way to Point Barrow. That will just be D.F. The rest of Mexico will follow "in good time".
