E 15 and Fuels Standard

the controversy over the use of E15

Groups like the Outdoor Power Equipment Institute and NMMA (National Marine Manufacturers Association) have issued strong warnings to consumers to pay attention to their fuels or risk severe engine damage.

Tips to Economy Fuel

Fuels Standard

which grew out of concerns about the oversupply and the belief that biofuels are good for the environment. The latest on federal standard requires that refiners use 36 million gallons of renewable fuels by 2022.

Boat owners are worried that E 15 fuel, which can damage boat engines and outboards, will become the new standard for fuel blends.

E15 fuel is a blend of 5 % gasoline and 15 % ethanol. The federal Environmental Protection Agency, in allowing its introduction into the marketplace, set standards designed to prevent problems in engines that are not equipped to handle the higher ethanol content.

The use of E 15 fuel

The use of E 15 fuel comes with many conditions, including a requirement that retail stations must provide at least one fueling position that offers gasoline containing no more than 10 % ethanol, there is concern among marine dealers that E15 will become.

The Problems of Ethanol

Bob Greco of the American Petroleum Institute said that increasing the ethanol content from 10 to 15 percent can cause problems, including fuel system component swelling, faulty check-engine lights, erratic fuel level indicators, and failure of other engine-parts that can lead to breakdowns.

Ethanol fuel attracts more moisture, and that can wreak havoc on boats. Fuel additives and maintenance help, but there are still problems, and customers don't need, the cost of maintenance.

Ethanol fuel burned in an engine producesmore than twice as much ozone as the equivalent amount of gasoline and it packs only two-thirds the energy per gallon of gasoline. As a result, boatmen get fewer miles per gallon using fuel blended with ethanol than with undiluted gasoline.

The use of E 15 fuel - Ethanol is corrosive to rubber and certain metals, so it can damage vital engine components. Ethanol also attracts and bonds with water from the air, and that water can separate out inside the tank due to phase separation.

If your boat sits for long periods between use, the moisture settles to the bottom of the fuel tank and can potentially clog in-tank pumps and fuel filters. Damage is also possible in fuel lines, gaskets, and valve seats as well as on older engines. That is the reason the US Environmental Protection Agency did not approve its use in boats, that may sit idle for long periods of time. It also is the reason that most marinas already use fuel additives in the gasoline they currently sell, with its 10 percent ethanol content. -That helps prevent issues.

Another Tank and System Problems , is that ethanol forms a brown goo when left in a fuel tank too long. That can clog fuel-system components.

Two-stroke boat engines, run hotter with an ethanol (a blend of gasoline and ethanol) blend, which accelerates the potential damage. And ethanol can wreak havoc on fuel tank useing fiberglass in older boats.

Algae-X Magnetic Fuel Conditioners

Installing Algae-X's Magnetic Fuel Conditioners and treating the fuel with AFC-705 fuel catalyst will improved the quality of the fuel and significantly enhanced engine combustion.

LG-X 500 - 1/2 in. NPT

The Algae-X system also dramatically lowered the maintenance and replacement of the costly catalytic converters by reducing the build-up of unburned fuel and soot.

"On the H. R. Morris, a 220' dredge vessel powered by four, 2,600-hp engines and corresponding generators, the soot deposits were reduced by 98% and the opacity of the exhaust smoke improved by at least 10-20%, while decreasing NOx levels. Manson vessels also carrying the Algae-X system include the Valhalla, the Valkyrie, and the tugs Cub and Pub, as well as others in Manson's fleet."

In US - Southern California, permits are required on diesel engines, and must include fuel consumption figures to calculate total NOx and emissions for each engine. Suspension of a permit could force installation of new engines on any vessel not in compliance. The Algae-X systems will allow to maintain certification of its fleet, while reducing operating and maintenance costs.

Ethanol-laced fuel (E10)

As ethanol-laced fuel becomes increasingly common, boaters are voicing concerns over potentially harmful effects on marine engines. Such fuels are commonly referred to as E10 blends, because ethanol is added as an oxygenate at ratios up to 10 percent in order to promote more complete combustion and thus reduce emissions.

Fuel components

Although there have been reports of fiberglass tanks and older fuel line components compromised by E10’s alcohol content, these are not big problems for most trailer vessels, which typically use plastic and aluminum tanks and feature systems designed for oxygenated fuels.

A more real concern is E10's affinity for water. And because Marine ethanol acts as a solvent that loosens boat tank deposits, you may suffer the double whammy of particulates and water collecting at the bottom of the boat tank and then entering the engine.

Resulting in clogged filters and poor performance. If this is a concern, a number of quality additives, including Sta-Bil®'s Marine Formula Ethanol Treatment and Stabilizer (
