Product Details

Complete Fuel Treatment for Higher-Level Biodiesel Blends

Bio Dee-Zol is a commercial-grade, all-purpose fuel treatment engineered specifically for higher-level biodiesel blends. While biodiesel offers many advantages, it also presents unique challenges—including reduced storage stability, increased moisture retention, deposit formation, and differences in combustion characteristics. Unlike conventional diesel additives, Bio Dee-Zol is formulated to address these biodiesel-specific issues while delivering the everyday performance improvements operators expect from a premium fuel treatment.

Ideal for fleets, agricultural equipment, municipalities, marine operators, fuel distributors, contractors, and anyone operating equipment on higher-level biodiesel blends, Bio Dee-Zol helps maintain cleaner fuel systems, improve engine performance, and protect fuel quality during both operation and storage.

Optimized for Biodiesel Performance

Biodiesel behaves differently than conventional diesel fuel. It is more susceptible to oxidation during storage, more likely to retain moisture, and more prone to forming deposits throughout the fuel system.

Bio Dee-Zol is specifically formulated to address these characteristics, helping maintain fuel quality while supporting reliable equipment operation and long-term fuel system health.

Improves Combustion and Engine Performance

Bio Dee-Zol combines cetane improvers and combustion enhancers to promote more complete fuel combustion. Improved combustion helps engines start easier, run smoother, produce less smoke, and deliver more consistent performance.

Regular use can also improve fuel economy and help restore engine responsiveness.

Cleans and Protects the Fuel System

Powerful detergent and dispersant technologies help remove and control biodiesel-related deposits in injectors, combustion chambers, and other critical fuel system components.

Cleaner fuel system components promote more efficient fuel delivery, improved combustion, and more reliable engine operation over time.

Stabilizes Biodiesel During Storage

Because biodiesel is naturally less stable than conventional diesel, maintaining fuel quality during storage is especially important.

Bio Dee-Zol helps stabilize biodiesel blends during storage while helping manage water-related fuel issues that can accelerate fuel degradation. Whether fuel is used daily or stored between seasons, regular treatment helps preserve fuel quality and improve long-term reliability.

One Treatment. Multiple Benefits.

Rather than relying on several individual additives, Bio Dee-Zol combines multiple performance technologies into one balanced formulation, including:

  • Cetane improver
  • Combustion improver
  • Fuel stabilizer
  • Detergent package
  • Deposit dispersants
  • Water-control technology

The result is a convenient, all-in-one treatment designed specifically for the needs of higher-level biodiesel blends.
