Semi Truck Fuel Additives That Keep You on the Road

At Fuel Ox, we understand the importance of protecting your engine, improving your fuel system, and stretching every fill up. Our semi truck fuel additives are crafted with high-performance ingredients that support better fuel economy and help reduce wear on essential components.

With regular use, these diesel fuel additives support peak performance in heavy duty trucks while also protecting against contamination and wear inside your tank. Whether you’re battling cold weather or hauling long distances, these additives help maintain consistent engine performance.

Fuel Ox® OTR Improves Fuel Efficiency and Reduces Emissions

Fuel Ox® OTR is one of our most reliable solutions for improving fuel economy in diesel engines. Designed to treat up to 120 gallons of diesel per dose, it promotes more complete combustion which means better mileage, cleaner injectors, and reduced diesel particulate filter build-up.

By lowering the combustion temperature, it enhances lubricity and helps reduce deposits inside the injectors and fuel filters. This helps maintain cleaner fuel lines and protects the entire fuel system.

Perfect for diesel engines in all fleets, Fuel Ox® OTR is a powerful fuel additive that supports overall engine performance and offers benefits similar to a fuel stabilizer. With better combustion and less soot, it’s easier on fuel system components like fuel pumps and injectors, helping prevent wear and boosting performance.

Fuel Ox® Cold Charge OTR Is a Must for Cold Weather Driving

When temperatures drop, diesel gelling becomes a threat to fuel flow. Fuel Ox® Cold Charge OTR provides anti gel protection specifically designed for winter conditions. Diesel fuel can thicken and stop flowing properly, damaging your filter or reducing mpg during cold starts.

This diesel additive also enhances combustion to help fuel burn cleaner and more efficiently. As a result, you reduce deposits in your injectors and protect the entire fuel system, from the tank to the fuel filters. Cold Charge OTR delivers vehicular power across long distances, keeping your truck ready to handle the heat of the job even when the outside air says otherwise.

Fuel Ox® Freeze Guard OTR Offers an Extra Layer of Winter Protection

Fuel Ox® Freeze Guard OTR was built for the bitter cold. It is designed to treat up to 120 gallons of diesel and lower the cold filter plugging point. This protects against fuel gelling, which is a common cause of failure in cold weather conditions. By keeping the fuel flowing smoothly through fuel system components like pumps and injectors, Freeze Guard prevents costly downtime caused by blockages or poor combustion.

It delivers the protection that diesel vehicles need when temperatures plummet. Freeze Guard supports the performance of diesel additives like Fuel Ox® Cold Charge but adds a layer of defense ideal for extreme conditions. For drivers who depend on every drop of fuel during winter, it’s a smart investment for maintaining consistent power and better mileage.
