Guide to Ultra Low Sulfur Diesel Explained
What is Ultra Low Sulfur Diesel? In 2001, the EPA created the Highway Diesel Program to reduce the amount of sulfur in diesel vehicles. It mandates a 97% reduction of sulfur oxides in diesel fuel, down to 15 ppm from a previous limit of 500 ppm. Ultra low sulfur diesel was born from this law. It went into effect in 2006 and post-2007 …
