Diesel Fuel Conditioner

Cleans fuel systems to reduce emissions, restore power and improve fuel economy.

The Problem

Modern diesel engines use a sophisticated fuel injection system to provide efficient engine operation. Deposit build-up in the fuel injectors affect the spray pattern contributing to poor performance, reduced fuel economy and increased emissions. Ultra-low sulfur diesel fuel often lacks the lubricity to protect critical fuel system components, which can lead to increased wear in pumps and injectors.

The Solution

BARDAHL PRO® Diesel Fuel Conditioner is a complete multi-functional diesel fuel enhancer that improves fuel system detergency, disperses water, boosts cetane, and provides additional vital lubricity. This keeps fuel systems clean, improves combustion, and reduces wear. The Engine Manufacturers Association (EMA) recommends the use of “premium” diesel fuel to get maximum performance. DFC converts regular diesel into premium-grade diesel fuel.


  • Disperses water and excess moisture
  • Converts regular diesel into premium-grade diesel fuel
  • Removes fuel injector deposits and keeps injectors clean
  • Restores injector spray patterns to improve power, performance, and fuel economy
  • Prevents deposits caused by the use of biodiesel blends
  • Increases cetane rating of fuel to improve combustion and reduce emissions
  • Enhances lubricity of fuel to protect pumps and injectors from wear
  • Protects entire fuel system from rust and corrosion
  • Suitable for use with all types of fuel injectors and safe with DPF and catalytic converters


Add to tank prior to filling up with fuel. One bottle treats up to 35 gallons. Use at every fillup. If the fuel system is dirty use CRDI Cleaner™ to quickly remove existing deposits; then use this solution to keep the fuel system clean and maintain power and performance. Dispose of any used or unused solution and container in accordance with local, state, and federal regulations.
