ValvTect® Marine Diesel

We know marine engines face extraordinarily challenging environments. That’s why Sprague is proud to offer the ValvTect® marine diesel brand. ValvTect® diesel is specifically designed to counteract the challenges found in low and ultra-low sulfur diesel (ULSD) fuels—increasing lubricity, reducing moisture levels, remaining stable for up to a year, combating bacterial growth and dramatically reducing filter plugging. Increased lubrication also protects injector and fuel pump wear—further protecting equipment. 

ValvTect® with BioGuard® eliminates the need for additional fuel additives to protect marine engines, so there’s no risk of improper additive use—saving you and your customers time and money.

Compared to traditional commercial diesel, ValvTect® marine diesel fuel offers significant advantages:
  • Contains BioGuard® micro-biocide
  • Free of bacteria and algae
  • Stabilized for up to one year
  • Contains extra moisture dispersants
  • Prevents sludge and plugged fuel filters
  • Cleans-up fuel injector deposits
  • Contains extra lubricity improvers
  • Improves power, performance and fuel economy

ValvTect® Marine Gasoline

Marine engines face challenging environments and operate at much higher RPMs than traditional vehicle engines—consuming 10x more fuel per hour. Sprague is proud to offer you ValvTect® marine gasoline, which is designed specifically for marine engines. It gives your customers a smart alternative to ethanol-blended gasoline, which is susceptible to phase separation and causes corrosion. With ValvTect®, you’ll save your customers time and money—giving them more reasons to purchase marine fuel from you. 

Compared with automotive gasoline, ValvTect® offers these significant advantages:
  • Stabilized for up to 1 year
  • Contains extra moisture dispersants
