What Is DX1?
DX1, formerly known as D-1280X, is a synthetic ester-based fuel reformulator designed to improve fuel efficiency, support combustion performance, and reduce harmful emissions - with historical testing spanning over three decades.
Fuel Reformulator
A synthetic ester additive that restructures combustion at a molecular level for cleaner, more complete fuel burn.
Lubrication Benefits
Creates a protective film on engine surfaces, reducing wear and extending the life of fuel-system components.
Emissions Reduction
Tested for reductions in HC, CO, NOx, particulate matter, smoke opacity, and CO₂ across multiple programs.
Decades of Research.
A Foundation of Evidence.
DX1 has been evaluated through laboratory testing, fleet studies, regulatory review, and field applications over more than three decades.
