CLEAN FUEL PROGRAM

Protect Your Equipment from Diesel Fuel Contamination

Fuel contamination is one of the leading causes of injector failures, fuel system damage, reduced engine performance, and unplanned downtime. Modern diesel engines operate with extremely tight tolerances, making them more vulnerable than ever to water, microbial growth, sediment, and particulate contamination.

Our Clean Fuel Program is designed to help fleets, generators, heavy equipment operators, agriculture, mining, transportation, and industrial facilities maintain cleaner fuel, improve reliability, and extend equipment life.

By combining proven fuel treatment technologies such as DQTubes®, Separ Filters, Reverso fuel polishing and fuel additives, testing, and preventative maintenance practices, we help customers take control of fuel quality before contamination becomes a costly problem.

DQTube | Remove Water Directly From the Tank

Water and sediment naturally settle to the bottom of diesel fuel storage tanks, where contamination can accumulate over time. DQTubes sit directly in this problem area and absorb free water from the fuel, helping manage contamination before it can be drawn into your equipment.

Best for: Passive, ongoing water management in diesel storage tanks.

Reverso Fuel Polishing | Clean Contaminated Stored Fuel

When contamination has already built up, Reverso fuel polishing systems circulate diesel out of the tank, separate water and debris, filter fine contaminants, and return cleaner fuel to storage. This recirculating process helps restore fuel cleanliness without requiring the tank's entire fuel supply to be discarded.

Best for: Cleaning bulk fuel storage tanks with existing water, sediment or particulate contamination.

SEPAR Filters | Stop Contamination Before It Reaches Your Engine

Even with good fuel storage practices, contaminants can still travel with diesel as it leaves the tank. SEPAR fuel filtration systems separate water and particulate contamination from the fuel before it reaches critical engine and fuel-system components, providing an additional line of protection for diesel-powered equipment.

Best for: Protecting engines and fuel systems from water and particulate contamination.

4+ Fuel Additives | Treat and Protect Your Diesel Fuel

Clean fuel is only part of maintaining diesel performance. 4+ Fuel Additives are formulated to improve fuel quality, support combustion and help keep diesel fuel systems clean and performing properly. Different formulations provide targeted treatment for seasonal conditions, fuel-system cleaning and ongoing diesel fuel performance.

Best for: Ongoing fuel treatment, performance and preventative maintenance.

Shop All 4+ Fuel Additives

A complete approach to cleaner diesel fuel starts at the tank and continues all the way to the engine. DQTubes help manage water inside storage tanks, Reverso systems polish contaminated stored fuel, SEPAR filters provide protection as fuel moves toward the engine, and 4+ Fuel Additives help maintain fuel quality and fuel-system performance.
