ValvTect Offers The Correct Fuel Additives For Winterizing Todays New Fuels

With changes in fuel blends over the last several years, boaters need to pay more attention than ever to the fuel additives they use on their boats at haul out time.


Ethanol gasoline blends and ultra-low sulfur diesel requires a multi-functional fuel additive to keep fuel “fresh” and protect the engine over the winter, a departure from just a few years ago when a simple single-function stabilizer would get the job done. Although most gasoline stabilizers will keep the fuel stable, they don’t provide protection from corrosion and phase separation that can ruin boaters’ engines and their next boating season.


In the case of E10 – the 10 percent ethanol blend that makes up much of the country’s fuel supply – boaters need to look for a multi-functional additive like ValvTect Ethanol Gasoline Additive  that includes a stabilizer, a corrosion inhibitor, a moisture dispersant that holds the moisture in suspension to help prevent phase separation and a detergent that will block deposits forming in the engine. 


Corrosion is the biggest concern with ethanol blends 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.


It is essentially the same situation with ultra-low sulfur diesel fuel. Less stable than the older diesel fuels, it goes “bad” more quickly, holds more water and can cause corrosion. Additives used for diesel fuel also need to be “multifunctional” like ValvTect BioGuard Plus 6 that contain a biocide that will prevent or kill bacteria, corrosion inhibitor, detergent and cetane improver.


The biggest problem for a boater choosing an additive is that there are no specifications for marine fuel additives.

“It’s kind of a ‘buyers beware’ situation,” said Marvin Griffin, President of ValvTect Petroleum Products, which supplies both marine fuel and marine fuel additives and private labels additives for engine manufacturers. “The ethanol situation created such a huge market for fuel additives that all kinds of companies came out of the woodwork,  with different products and made all kinds of unsupported claims. Most of those products were never tested to prove performance or that they would not harm engines when used over a long period of time.”


There are steps a boater can take to help decide which additive to use in their boat. They should find out if it contains the necessary components outlined above – corrosion inhibitor, moisture dispersant, stabilizer, detergent, biocide, etc. Most importantly, boaters should ask if the additive they want to use has been tested and does the testing meet ASTM specifications.


Finally, be leery of any promises made by an additive supplier that sound too good to be true, such as that the product “restores bad or phase separated fuel” or can “solve E15 problems.”

“There aren’t any additives on the market that can prevent E15 caused engine damage, restore bad fuel or safely restore ethanol-blended fuel that has phase separated,” Griffin said.  “The engine you save might be your own.”

ValvTect Ethanol Gasoline Treatment meets all ASTM specifications. Also, ValvTect Ethanol Gasoline Treatment is the ONLY product to post the actual tests and test results in ads and literature to meet the "proof of performance" boaters should require of the product they purchase.

To prove the total performance of ValvTect Ethanol Gasoline Treatment, ValvTect Petroleum authorized a series of independent laboratory tests at one of the nation’s leading petroleum laboratories. The tests proved ValvTect Ethanol Gasoline Treatment improved the stability of E10 (90% gasoline and 10% ethanol) by 186%. It received a perfect A rating to totally prevent corrosion and showed the ability to help prevent phase separation, especially during winter storage when fuel cools down. 
ValvTect’s BioGuard Plus 6 is the only diesel additive available in the United States that contains an EPA approved biocide plus stabilizer, corrosion inhibitor and water dispersant. It will prevent bacteria, stabilize diesel fuel for up to two years and prevent sludge and corrosion. BioGuard Plus 6 eliminates the need to purchase, handle and measure multiple products. All the components are compatible, are the correct ratio and less expensive than purchasing multiple products. 
“Using the correct products for winterizing can determine whether boaters have an enjoyable spring or lots of problems,” Griffin said. “Corrosion and bacteria take a long time to develop but once they do, they can ruin a boating season..
