EPA approves ValvTect BioGuard Plus 6™, the only biocide that prevents bacteria and provides six other benefits.

ValvTect BioGuard Plus 6 prevents bacteria and solves all other diesel fuel related problems - eliminates need for multiple products.


Jerry Nessenson, president of ValvTect Petroleum, announced today that ValvTect has received formal approval for the registration and sale of ValvTect BioGuard Plus 6 multifunctional biocide diesel additive from the U.S. Environmental Protection Agency (EPA) and in all 50 states. 

“Prior to the EPA’s approval of ValvTect BioGuard Plus 6, all biocides registered for use in ultra low sulfur diesel fuel were single function biocides designed to only kill or prevent bacteria. Now boaters can use BioGuard Plus 6, a single formula, multifunctional biocide that also includes a stabilizer, corrosion inhibitor, moisture dispersant, detergent, cetane improver and lubricity improver, all in one convenient container,” Nessenson said.                                                             
Ultra low sulfur diesel fuel, now required by the EPA to be sold by virtually all marinas, contains less than 15 parts per million (a 90% reduction) of sulfur and is better for the environment. However, it can cause a multitude of fuel related problems and requires more than just a biocide that only prevents bacteria.                     
Ultra low sulfur diesel fuel quickly becomes unstable and contains a high moisture content that leads to corrosion, sludge and plugged fuel filters. More importantly, the  sulfur in high sulfur diesel fuel lubricated the fuel injectors and fuel pump. The lack  of lubrication can cause expensive premature failure of injectors and fuel pumps unless the ultra low sulfur diesel is treated with a lubricity improver.                      
“To offset the multiple problems that can be caused by ultra low sulfur diesel fuel, boaters have been forced to use several products. This has been a confusing, inconvenient and expensive process. ValvTect’s BioGuard Plus 6 contains BioGuard micro-biocide and six other additional components, including a lubricity improver, all compatible and in the correct ratios, to provide boaters with the best protection at the lowest cost,” Jerry Nessenson said.                                                 
BioGuard Plus 6 is now available at West Marine and other marine supply dealers across  the US in quart containers that treat 375 gallons and one gallon containers that treat 1,500 gallons of diesel fuel.Larger container sizes are also available. For more information, visit
