Bio Dee-Zol Plus

Complete Biodiesel Performance—Now with Cold-Weather Protection

Bio Dee-Zol Plus is a commercial-grade, all-purpose fuel treatment engineered specifically for higher-level biodiesel blends. It delivers the same comprehensive fuel treatment benefits as Bio Dee-Zol—including improved combustion, cetane enhancement, injector cleaning, fuel stabilization, and water management—while adding biodiesel-specific cold flow improver technology to help maintain reliable performance in colder temperatures.

Ideal for fleets, municipalities, agricultural equipment, marine operators, contractors, fuel distributors, and anyone operating higher-level biodiesel blends throughout the year, especially in climates where cold-weather operability is a concern.

Optimized for Biodiesel Blends

Biodiesel presents unique fuel challenges that differ from conventional diesel. Higher biodiesel blend levels are generally more susceptible to oxidation, deposit formation, moisture-related issues, and cold-weather operability problems.

Bio Dee-Zol Plus is formulated specifically to address these biodiesel-specific characteristics while providing year-round fuel system protection and performance.

Improves Combustion and Engine Performance

Bio Dee-Zol Plus combines cetane improvers and combustion enhancers to promote more complete fuel combustion. The result is smoother engine operation, improved engine responsiveness, reduced smoke, and better overall fuel performance.

Regular treatment can also help improve fuel economy while maintaining cleaner combustion.

Cleans and Protects the Fuel System

Detergent and dispersant technologies help remove and control biodiesel-related deposits throughout the fuel system, including injectors and combustion chambers.

Cleaner fuel system components promote improved fuel delivery, more efficient combustion, and more consistent engine performance.

Built-In Biodiesel Cold Flow Protection

Unlike conventional diesel, biodiesel blends often begin experiencing cold-weather operability problems at significantly warmer temperatures. Cold-weather performance can also vary depending on the biodiesel feedstock and blend composition.

Bio Dee-Zol Plus incorporates biodiesel-specific cold flow improver technology that helps improve low-temperature fuel flow and operability while reducing the likelihood of fuel thickening and cold-weather filter plugging. This added protection helps support more dependable winter performance without requiring a separate cold flow treatment in many applications.

Stabilizes Fuel During Storage

Bio Dee-Zol Plus also helps stabilize biodiesel blends during storage by slowing oxidation and helping manage water-related fuel issues that can contribute to fuel degradation.

Regular use helps maintain fuel quality whether the fuel is consumed quickly or stored for extended periods.

One Treatment. Multiple Benefits.

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

• Cetane improver
• Combustion improver
• Fuel stabilizer
• Detergent package
• Deposit dispersants
• Water-control technology
• Biodiesel-specific cold flow improver

The result is one convenient treatment that helps maintain biodiesel performance throughout the year.
