Heavy Duty Vehicle Performance
Enhancing performance in fuel economy, power, and acceleration.

In recent years, the diesel fuel and engine landscape have changed considerably.  Sulfur levels have been reduced globally to enable implementation of advanced exhaust treatment systems that significantly reduce vehicle emissions and enable advanced exhaust treatment systems. OEMs have turned to new generations of engine technology to improve performance and emissions, leading to injection systems with higher pressures, higher temperatures, and lower clearances.  

With the proliferation of Ultra-Low Sulfur Diesel (ULSD) and the widespread use of High-Pressure Common Rail (HPCR) injection systems, a new generation of issues can negatively impact diesel engine and fuel system performance.  Heavy-duty diesel performance additives clean and protect vital fuel-system components to help heavy-duty vehicle and equipment engines maintain design performance over the years and miles. 

Our diesel performance additives enhance performance in key areas such as fuel economy, power, and acceleration, while also helping to reduce emissions to protect the environment.  By providing vital whole engine system protection, they also minimize vehicle and equipment downtime.

Afton’s patented Greenclean® deposit-control detergent technology is the backbone of our heavy-duty diesel additives. It delivers proven performance in both on-road and off-road applications.

Afton additive solutions can be tailored to address  specific regional challenges associated with variable fuel quality issues around the world.  Combined with additional active technologies, such as cold flow improver and lubricity, our tailored solutions can meet your entire range of challenges, from fuel economy to operational robustness.

Whether you are looking to improve heavy-duty engine performance in agriculture, construction, mining or over-the-road, Afton Chemical has the solution.
