High-Quality Diesel Additives for Semi Trucks

Fuel Ox diesel additives do more than boost performance, they tackle your fleet’s biggest maintenance cost: emissions-related failures. By reducing soot emissions by over 70%, our Fuel Ox With Combustion Catalyst additive dramatically cuts down on DPF regens, EGR cooler clogs, and sensor malfunctions, the leading causes of downtime in modern diesel trucks. 

Less soot means fewer regens and cleaner exhaust systems, saving thousands in parts and labor. Plus, by lowering NOx emissions, DEF usage is reduced by up to 15%, adding even more cost savings. Whether used as a single treatment or long-term solution, Fuel Ox With Combustion Catalyst protects your engine, stabilizes fuel, and delivers cleaner combustion where it counts.

Everyday Efficiency Formulas Engineered For Truckers

For trucking companies looking for streamlined operations, Fuel Ox® OTR combines the power of our Fuel Ox® with Combustion Catalyst and Cold Charge into a single-dose additive used with every fill-up.

It’s a convenient, all-in-one solution that improves combustion efficiency, enhances power, and boosts fuel economy. During winter months, it also protects against diesel gelling, ensuring filters remain clear and fuel flows freely even in freezing temperatures.

Winter Protection with Cold Charge, Freeze Guard, Winter Max, and Heat Bomb

When temperatures drop, anti gel protection becomes critical. Fuel Ox offers anti gel products that prevent gelling and ensure reliable starts in freezing temperatures. These additives protect the fuel system by preventing wax crystals from forming in diesel fuel and clogging filters.

All of these products help diesel engines in cold climates maintain performance, mileage, and fuel efficiency without interruption.
