Do Diesel Fuel Additives Really Work? A Chemist Explains the Science
This video was first publish on Pickup Truck Plus SUV Talk
Do diesel fuel additives really work, or are they just expensive snake oil? With diesel prices remaining painfully high, improving fuel economy, reducing regens and protecting expensive emissions equipment could make a meaningful difference for diesel truck owners.
In this video, Tim Esterdahl speaks with Power Service Products chemist Jessica Crabtree about how diesel fuel additives are tested and what they can potentially do inside a modern diesel engine.
Crabtree explains how detergents can clean diesel injectors, improve combustion and reduce soot traveling through the EGR, turbocharger and diesel particulate filter. She also discusses preliminary testing involving eight 3.0-liter Duramax diesel trucks that has shown an average fuel economy improvement of approximately 15%. That field trial is still underway, and individual results can vary considerably.
The conversation also covers:
How quickly dirty diesel injectors can be cleaned
Whether additives can reduce DPF regeneration frequency
Potential reductions in DEF consumption
How additives affect the EGR and turbocharger
Why older diesel trucks may show larger improvements
The difference between laboratory testing and YouTube garage testing
A Peterbilt case study that improved from 5.9 to 8 mpg
