BioGuard Plus 6™ is the only EPA-registered fuel biocide containing a multifunctional high performance diesel additive.

Microorganisms that grow in diesel fuel systems, such as bacteria, yeast and mold, are known as “bugs.” “Bugs” live in virtually all diesel fuel systems. They live in the water found in all fuel systems and eat the fuel as a nutrient source. Because some water is present in virtually all diesel fuel systems, these systems are a good environment for biological growth. The most common places for “bugs” include the fuel/water interface near tank bottoms, on storage tank walls, and in sediment. Left unchecked, “bugs” will corrode fuel systems and create slime & sludge that plugs fuel filters & fuel lines. The result of contamination is increased maintenance costs and expensive down time.

BioGuard Plus 6™ (BGDP6) in Lenoir, North Carolina

BioGuard Plus 6™ is the only EPA-registered fuel biocide containing a multifunctional high performance diesel additive. BioGuard Plus 6™ contains BioGuard to prevent microbial contamination, fuel filter plugging and other bacteria-caused problems.

BioGuard Plus 6™ is also formulated with six additional components to help prevent ULSD & biodiesel-related problems to significantly improve heavy-duty diesel engine performance. BioGuard Plus 6™ contains Diesel Guard™, which is documented to keep injectors, combustion chambers & fuel filters cleaner. It is also documented to improve fuel economy up to 7.6% in SAE Type II testing.

Introducing ValvTect BioGuard plus 6

One product that solves all diesel fuel problems! BioGuard Plus 6 is specially formulated to prevent bacteria and algae, plus all other diesel fuel-related problems.

  1. Stabilizes Up To 2 Years: Today’s low, ultra-low sulfur diesel fuel and biodiesel become unstable quickly, reduce fuel filter life and can cause filter plugging. BioGuard Plus 6 contains a diesel fuel stabilizer that keeps the fuel fresh and can double fuel filter life.
  2. Prevents Corrosion: BioGuard Plus 6 contains a rust and corrosion inhibitor to protect the entire fuel system.
  3. Lubricates Pumps & Injectors: Lower sulfur diesel fuel can cause premature wear of fuel pumps and fuel injectors. BioGuard Plus 6 contains VT 101 lubricity improver to extend fuel pump and fuel injector life.
  4. Disperses Moisture: Lower sulfur diesel and biodiesel contain high levels of moisture that can cause corrosion and sludge that can plug fuel filters. BioGuard Plus 6 contains moisture dispersant that holds moisture in suspension to help prevent corrosion, prevent sludge and extend fuel filter life.
  5. Cleans Up Injector Deposits: BioGuard Plus 6 contains Diesel Guard7 diesel detergent to clean-up carbon deposits. Clean fuel injectors can improve fuel economy up to 6%.
  6. Increases Cetane: BioGuard Plus 6 contains cetane improver. A higher cetane diesel fuel burns more completely and cleaner; results in less smoke, odor and soot; and reduces harmful exhaust emission.
