Here's why:
* Different Fuel Formulations: Off-road diesel fuel (also known as red diesel) is not the same as on-road diesel fuel. It contains a higher concentration of sulfur and other additives that are not suitable for modern diesel engines, including the 2010 Cummins.
* Engine Damage: The high sulfur content in off-road diesel can lead to:
* Increased wear and tear on engine components: The sulfur can corrode and damage engine parts like fuel injectors, fuel lines, and the catalytic converter.
* Reduced engine performance: The buildup of sulfur deposits can clog engine components, leading to reduced power, fuel economy, and increased emissions.
* Increased maintenance costs: Frequent repairs due to off-road diesel damage can be expensive.
* Emission System Issues: The 2010 Dodge Cummins engine is equipped with a sophisticated emissions system that is designed to meet strict EPA standards. Off-road diesel can damage the emissions system components, such as the diesel particulate filter (DPF), and lead to engine malfunctions and potentially illegal emissions levels.
Conclusion:
While off-road diesel fuel may be cheaper, it is not recommended for use in a 2010 Dodge Cummins engine. Using the correct on-road diesel fuel will ensure optimal engine performance, longevity, and compliance with emissions regulations.
Note: Always consult your vehicle's owner's manual for specific fuel recommendations and maintenance guidelines.
