Annual Update re Mexican Diesel Fuel
Now that the annual Snowbird migration is underway, I'm already getting emails from owners of 2007.5 through 2013 diesel pickups who are looking for updates on the effects of the higher sulfur Mexican diesel.
So, here goes:
1.
Mexico still has not fulfilled the promise it made 5 years ago to introduce ulsd (ultra low sulfur diesel maximum 15ppm of sulfur) across Mexico. As a result, much of the country is still supplied with lsd (maximum 500 ppm of sulfur).
2.
There is now extensive data available regarding the behaviour of 2007.5 through 2010 diesels, and none of them, regardless of whether it is Ford, Dodge, or GM, are experiencing long term problems. Most owners will be completely unaware of any sulfur effects, while some may notice blue smoke being emitted during regenerations. Once the vehicle returns to the USA, any remaining sulfur gets burned out of the system.
3.
For the 2011 model year and later, there can be some serious issues, including messages which threaten "limp mode", but all of these conditions are manageable and can be cleared with the right procedures. The effects are temporary, and are due to more stringent emissions monitoring as of 2011.
GM products 2012 and later are particularly sensitive to sulfur. Owners of these vehicles are almost certain to receive error code messages over the winter season in Mexico.
4.
As always, I am NOT counselling owners to take their pickups into Mexico, but if they do, and need help with error codes and warning messages, they should feel free to contact me. I do have solutions to all known issues related to sulfur in the fuel
