Driving the Pan-American Highway with a Modern Diesel Vehicle — Where Can I Find ULSD?
This article discusses the ULSD availability & Diesel quality along the PanAm Highway.
A few words before we begin
Modern Diesel engines require a particular type of Diesel with a very low content of sulfur. This type of Diesel is called Ultra-low-sulfur diesel (ULSD).
Most modern vehicles require ULSD and also Diesel exhaust fluid (DEF) or AdBlue as it is typically called in Europe. If your vehicle uses DEF/AdBlue it will refuse to work if you run out of it.
