This Ain’t Your Daddy’s Fuel – 2016 Marine Fuel Issues and Solutions


Recent fuel regulations present new fuel challenges in addition to the traditional issues. It is important to properly address each of these in order to ensure the best performance, reliability and economy from your engine.

All standard gasoline in the U.S. can have up to 10% ethanol (known as E10), per federal regulations. Proposed legislation would increase this amount to 15% ethanol (E15). E15 is known to be corrosive to fuel lines and components. Ethanol also suffers phase separation and causes fuel to decay faster than normal. In addition, ethanol fuels are very abrasive, being known to cause premature fuel injector failure.

Modern diesel fuels suffer similar problems. Biodiesel content is now mandated at at least 5% in #2 diesel fuel, bringing about all the aforementioned problems with ethanol to diesel. In addition, ULSD requirements have significantly reduced the amount of sulfur in diesel, which was a main lubricator, further increasing the abrasiveness of the fuel on injectors and other components. Biodiesel also condensates at a much quicker rate than traditional diesel, so problems like bacteria, algae, and fungus growth, as well as damage to injectors can occur.

It is recommended to have stored fuel tested on a regular basis. Fuel can be tested for bacteria growth, water content, cloud point, flash point, and lubricity, among others. This can be done with fuel testing kits or by sending a fuel sample to a lab. The good news is that some issues can be avoided by proper storage and handling. Other issues inherent to the fuel can be treated and prevented in the future by using Mileage Mate FCC. Mileage Mate FCC is proven by independent third-party testing to significantly increase lubricity, remove water from fuel, prevent phase separation, kill and prevent bacteria, algae, and fungus growth, and clean gums, waxes and varnishes from the fuel system. And it does this without alcohol or other harsh chemicals.
