Can you use Mexican diesel in your 2008 super duty diesel truck?

Answer 1

Diesel sold outside of the United States may not meet the US standard for ultra-low sulfur diesel. Ultra low sulfur diesel contains 15 PPM of sulfur, whereas diesel sold in countries such as Mexico will most likely have upwards of 500 PPM (parts per million) of sulfur. Using this diesel in a 2008 Super Duty will quickly cause very severe and costly damage to the emissions components of the vehicle. The diesel particulate filter in particular will likely be clogged very quickly due to the excessive amounts of soot generated when using fuel containing high amounts of sulfur. The symptoms of using fuel containing high amounts of sulfur will also be immediately noticeable if the truck were to be taken in for repair, likely voiding the warranty on the vehicle.
