Mexican Diesel Fuel/Sulfur Effects Update
Much to my distress I just learned here in the Southern Baja that the owner of a late model GM diesel pickup paid almost $3,000 to ship his truck back to the USA when it went into limp mode (5 mph) in...

Regarding the 2015 Powerstroke using Mexican LSD diesel, last January the owner (Chris) of a 2015 Ford diesel F350 took a caravan tour south on the Baja to Cabo. He had no issues while towing his fifth wheel trailer along the caravan route. However, after arriving in Cabo, he left the caravan group and traveled to La Paz where he stayed for several weeks with the trailer parked while he drove the truck around town.
After a few weeks the truck had its engine light come on and the owner continued to drive the truck until it went into limp mode. It is a fact that no dealer in Mexico can service Ford pickup late model diesels, so he called a dealership in the States which, when they found out he was in Mexico, canceled the warranty on his almost new 2015. He ended up bringing a delete kit into Mexico and removing the entire factory emissions system.
The puzzling thing about this case is that I have no other examples of any Ford, of any year, going in to limp mode on Mexican diesel, and we have no way of knowing whether this owner's issue was caused by sulfur in the fuel, or by the unrelated failure of an emissions system component. That is why I have been posting alerts about the 2015 Ford diesel pickups.
As a result of the confusion about this case, I have been recommending, until there is more data available, that owners of 2015 and later Ford diesel pickups bring an Edge CT2 tuner with them into Mexico, because the Edge CT2 can force a regeneration to burn sulfur out of the system. Owners should use the Edge CT2 to force a regeneration if the engine light or any other emissions message comes on - a regeneration is all that is required to fix the temporary sulfur poisoning. Owners need to call Edge at 1-888-360-3343 and make sure they order the correct model for their truck. https://edgeproducts.com/
It is important to note that I do NOT make any commission for the sale of Edge products, and I have no connection whatsoever to the Edge company. My ONLY interest is in helping owners of late model pickups cope with problems they experience using Mexican LSD.
The trucks which have the most problems are GM products. I have a 2015 Duramax powered Silverado myself, so I know from direct experience that limp mode can happen, and it takes specialised equipment to run a Service Regeneration, followed by a Reductant (DEF) Quality Test to get the vehicle out of limp mode.
In the past ten days I have assisted 3 separate owners of GM pickups, two with 2012 model year, and one with 2013 model year, deal with speed limitation issues after the POOR QUALITY DEF warning light came on and speed limitation messages were being displayed.
Mexican LSD is a VERY SERIOUS PROBLEM for all Duramax powered pickups 2012 through 2016, and possibly the 2015 Ford, per the information above. Dodge pickups with the Cummins engine appear to have no problems other than the occasional engine light on, and DEF consumption up to 3 times the normal amount. (The Dodge emissions system uses increasing amounts of DEF to compensate for the decrease in efficiency of the SCR as it becomes sulfur poisoned).
If Pemex can't get it's act together and begin producing ULSD, hopefully in 2017 when foreign oil companies can begin importing their own fuel in to Mexico there will be service stations carrying ULSD all across Mexico. Can't wait for an Esso or Shell station down the street carrying ULSD from the USA or Canada.
