Choosing the Correct Fuel for Today’s Engines

Published: Thursday, August 17, 2017

With changes in fuel blends over the last several years, boaters need to pay more attention than ever to the fuel they use and the fuel additives they put in their fuel tanks.

ValvTect Marine Gasoline and ValvTect Marine Diesel Fuel sold at Certified ValvTect Marine Fuel Marinas throughout the country are specially formulated for marine engines. Both fuel types contain the correct additives in the right proportions to assure boaters receive the maximum benefit from their fuel purchase. ValvTect Marine Fuels goes beyond typical “automotive” gasoline and “truck” diesel. By adding additional refinery-proven additives like stabilizers, corrosion inhibitors, moisture control, proper detergents, biocide, and other components, hardworking marine engines are kept in like-new condition and achieve the maximum performance level and fuel economy they can achieve.

ValvTect Marine Gasoline is specially formulated to protect and enhance the performance of hard working marine-grade gasoline engines. ValvTect Marine Gasoline exceeds the most stringent industry standards and goes “Beyond Top Tier” performance levels. It contains a state-of-the-art gasoline detergent that provides peak performance equivalent to improved fuel economy and performance due to the clean-up of power-robbing engine deposits. In addition to this state-of-the-art detergent package, ValvTect Marine Gasoline also contains corrosion inhibitors and moisture dispersants to help fight the effects of 10% ethanol gasoline which makes up the majority of this nation’s gasoline supply. Fuel containing extra corrosion inhibitors and moisture control is important, because ethanol can hold up to four times as much moisture as traditional gasoline. While bad fuel or phase separation can be a nuisance, it can be fairly easily solved by simply replacing the fuel. Corrosion, on the other hand, can lead to engine failure. Additionally, extra gasoline stabilizers protect engines during periods of nonuse and protects gasoline during storage for over one year. This assures boaters of easier starts and a better boating experience every time they go out.

ValvTect Marine Diesel: Diesel boaters know all too well the problems with diesel fuel such as bacteria, water, corrosion, and poor lubricity, just to name a few. Some of the increases in these problems can be traced back to the introduction of ultra-low sulfur diesel and biodiesel. The solution to these and many other problems can be overcome by using ValvTect Marine Diesel fuel.

This unique, specially formulated diesel fuel contains BioGuard biocide to help prevent bacteria. This filter plugging headache can ruin any boaters’ day. BioGuard biocide has been proven to be one of the most effective in preventing the formation of bacteria. Additionally, ValvTect Marine Diesel provides these other important benefits:

  • Lubricity improver lubricates fuel pumps and injectors to prevent pre-mature wear.
  • Diesel fuel is stabilized for over one year and can double fuel filter life.
  • Corrosion inhibitor prevents corrosion to protect the entire fuel system.
  • Moisture control disperses water to help prevent sludge and extend fuel filter life.
  • Increased cetane allows the diesel fuel to burn more completely to reduce smoke, soot, and harmful exhaust emissions.
  • Concentrated detergent cleans up injector and carbon deposits that can reduce fuel consumption as much as 6% as documented by the SAE Type II Fleet Fuel Economy Test.

To combat this problem, all Certified ValvTect Marinas must have their fuel tanks tested before they are allowed to sell ValvTect Marine Fuels and up to twice a year thereafter once they become a Certified ValvTect Marina. This testing, plus special hydroscopic fuel filters that are required to be installed on all ValvTect Marinas’ fuel pumps, helps to ensure boaters that ValvTect Marine Gasoline and ValvTect Marine Diesel are free of contamination.

When ValvTect Marine Fuels are not available in your area, add ValvTect XP+ Gasoline Treatment for gasoline or BioGuard Plus 6 for diesel to get equivalent performance as ValvTect Marine Fuel. These popular aftermarket containers are sold at most marine dealers and marinas nationwide.
