Industry-Leading Diesel Fuel Additives

At Fuel Ox, we know what it takes to keep diesel trucks and semi trucks running at their best. Since 2014, we’ve been working with truckers who demand performance, reliability, and a return on their investment.

That’s why we offer advanced diesel fuel additive products that not only improve power and fuel economy but also protect your fuel system components from wear and buildup. Whether you’re managing a fleet or running solo, Fuel Ox has the fuel additive for diesel engines you can count on to keep your truck moving forward.

Diesel Fuel Additives Keep Your Truck Running Strong

Untreated diesel fuel can lead to hard starts, carbon buildup, injector fouling, and clogged filters, none of which you want mid-haul. Our diesel additives are engineered to fix these fuel problems by cleaning out your fuel system, improving fuel flow, and delivering added lubricity to essential fuel system components like injectors, fuel pumps, and lines.

When diesel fuel burns cleaner and more completely, your engine runs smoother, emits less smoke, and delivers better mileage. It’s a measurable benefit we’ve seen in field data and in the feedback from countless operators who rely on our additive every time they fill the tank.

Semi Truck Fuel Additives Built for Long Hauls

If you’re driving a semi, downtime equals lost revenue, and fuel problems are a major culprit. Fuel Ox’s diesel fuel additives are built to withstand the extreme demands of heavy-duty engines. Our products protect fuel system parts from wear, stabilize diesel over time, and help prevent gelling in cold weather by acting as an anti gel. For fleet managers and long-haul drivers, the benefits are clear:

  • Reduced risk of gelling and filter blockages
  • Extended life of injectors, fuel pumps, and emissions equipment
  • Fewer breakdowns and costly repairs

We’ve tested these products in real-world conditions, from sub-zero climates to dusty job sites, to ensure they deliver on every claim. No gimmicks, just proven effectiveness that helps fleets and owner-operators stay on the road.

Diesel Fuel Additives That Improve Fuel Efficiency and Lower Costs

When margins are tight, squeezing out every extra mile matters. Our diesel fuel additive technology enhances fuel economy by supporting more complete combustion and reducing wasted energy. Less friction and cleaner burn equal improved fuel mileage, lower cost per mile, and fewer repairs over time.

This isn’t just anecdotal, customers have seen improvement across a range of equipment, including tractors, construction rigs, and on-highway trucks. We know how to measure results, and we build our products to deliver.

Sustainable, American-Made Diesel Fuel Additives

Fuel Ox stands for more than just performance. We’re a U.S.-founded company driven by sustainability and innovation. Our diesel fuel additives use advanced formulations designed to improve lubrication, reduce emissions, and protect your engine, without relying on harsh solvents or chemicals that damage equipment or the environment.

We don’t just talk a big game; our products are tested, proven, and trusted by people who work in the harshest conditions. From pump durability to wear scar reduction, our formulas offer industry-leading protection for your most valuable equipment.
