Industry Leading Diesel Fuel Additives to Protect Your Investment

At Fuel Ox, we believe the right diesel fuel additive isn’t just about keeping your engine clean, it’s about protecting your fuel system, improving fuel economy, and helping your equipment run efficiently. Whether you’re managing a fleet of diesel trucks or topping off the tank in your personal vehicle, our industry leading additive products offer a unique blend of performance, efficiency, and environmental responsibility.

With advanced formulas made for real-world conditions, we create additives that reduce carbon deposits, clean injectors, stabilize diesel fuel, and help improve the combustion process in all types of diesel engines and even carbureted engines.

Diesel Fuel Additives Make a Real Difference

Your engine works hard, and it needs support to stay clean, reliable, and powerful. Fuel Ox fuel additives are designed to clean out contaminants, improve air-fuel mixture burn, and keep intake valves, fuel injectors, and combustion chambers working as intended.

Drivers see the benefits of cleaner fuel burn: fewer emissions, better fuel mileage, and smoother operation. Whether it’s day-to-day use or part of your preventative maintenance plan, consistent use of quality additive packages makes sense for any gasoline or diesel setup. It’s also a simple way to save money by avoiding issues like clogged valves, stuck injectors, or premature oil changes.

Fuel Ox Combines Technology and Sustainability

We don’t believe you should choose between performance and the planet. Since 2014, Fuel Ox has offered additives that protect both. Our fuel system solutions were built for tough jobs and harsh conditions, with many products using biodegradable solvents, natural lubrication enhancers, and water dispersants that fight condensation and contaminants in your diesel fuel or gas.

From power service fleets to solo truck operators, Fuel Ox serves customers looking for long-term reliability and short-term improvement. Our manufacturer-approved blends meet or exceed EPA expectations while helping reduce pollutants in the air and extending component life.

Clean Injectors with the Right Fuel Additive

One of the biggest threats to engine efficiency is a dirty fuel injector. Over time, poor quality fuel leads to carbon and varnish buildup that throws off the air fuel mixture, causes poor combustion, and chokes out power. A high-quality fuel injector cleaner can reverse this damage and restore proper flow to your combustion chamber.

Our fuel additive lineup includes powerful detergents and solvents to keep injectors, intake valves, and components free from buildup. Unlike cheap additive products that offer surface-level fixes, ours dig deep, cleaning the entire fuel system for a complete fuel system clean. The result? Fewer regens, better mileage, more power, and cleaner exhaust.

Choosing the Best Fuel Additive for Diesel Vehicles

Not every fuel additive is created equal. Some focus on one benefit, while others try to be everything at once and fail. The best fuel additive for your diesel depends on your goals, whether it’s improvement in mileage, better cold-weather operation, or protection from contaminants. Here’s what makes Fuel Ox different:

  • Patented combustion catalyst for complete and efficient fuel burn
  • Built-in fuel stabilizer and water dispersants for long-term storage
  • Compatible with both gasoline and diesel fuel, across cars, trucks, and industrial engines
  • Helps reduce emissions, lower DEF usage, and support efficient combustion

Every fill up becomes a chance to make your engine cleaner, your fuel stretch further, and your vehicle run better. That’s the kind of light impact with heavy-duty results that just makes sense.

Ordering from Fuel Ox Is Simple and Reliable
