Isobutanol and Going Ethanol Free

Why Gulf Uses Isobutanol: 

Some our fuels use an additive called ISOBUTANOL, an advanced biofuel, to replace ethanol. Isobutanol is an EPA Approved oxygenate containing 30% higher BTU than ethanol, while producing power beyond typical ethanol-based gasoline.

ISOBUTANOL is not hygroscopic which means it will not absorb nor accumulate water, nor will the fuels damage or affect gas tanks, gaskets, carburetors or injectors. Our fuels, using ISOBUIANOL, meet all engine makers requirements which means these fuels will not void engine warranties.  The National Marine Manufacturers Association has endorsed gasoline containing ISOBUTANOL as being better that using fuels containing ethanol.

Gulf fuels containing ISOBUTANOL are excellent for everyday engines and high performance engines operating is high humidity environments or any environment around water. The fuels can also be used in engines that are used only occasionally as the fuel when static will not absorb water.  Racing applications include Hydroplane drag boats, offshore racing boats, high altitude racing and snowmobiles.

Why Ethanol free better for your engine:

Ethanol-based gasoline’s present a variety of problems to engine and fuel systems as the fuel will absorb water hygroscopically and any water present in the fuel system.  Typically gasoline and water do not mix a separate upon contact.  An ethanol-based gasoline will absorb accumulated water in a fuel system.  Adding water to gasoline is not good for an engine and results in poor performance and can create mechanical issues with misfiring.  Ethanol also attacks some fuel system components like hoses, gaskets and carburetors.  Many off road engine makers discourage the long term use of ethanol-based gasoline.

Facts about Isobutanol: 

  • Isobutanol is a second generation biofuel with several qualities that resolve issues presented by traditional ethanol.
  • relatively high energy density, 98% of that of gasoline.
  • does not readily absorb water from air, preventing the corrosion of engines and pipelines.
  • can be mixed at any proportion with gasoline, meaning the fuel can "drop into" the existing petroleum infrastructure as a replacement fuel or major additive.
  • can be produced from plant matter not connected to food supplies, preventing a fuel-price/food-price relationship.
  • Fuels containing Isobutanol will not void engine warranties and are endorsed  as better fuels by many engine makers

Regulation of Isobutanol:

Our fuels containing isobutanol are approved by the Environmental Protection Agency (EPA) and the National Marine Manufacturers Association (NMMA) as being better and preffered over ethanol-based gasoline fuels. Gulf fuels that contain isobutanol are accepted for engine and running equipment warranties.  NMMA reports that the isobutanol-based gasolines are much less harmful than ethanol-based gasoline.

Our fuels that contain Isobutanol are: 

Gulf MARINE, Gulf ATV and Gulf Off Road.  Gulf also produces a fuel for the Radical Sports Cars that contains isobutanol.

Applications:

All types of off road engines for boats, generators, ATV’s, snowmobiles, as well as High performance marine craft's, power boat racing, drag boat racing and high altitude racing.

See the difference in our side by side time lapse video of the Gulf Marine Gas (Left Side, Green) and Premium E10 gas (right side, yellow). This video is compressed from 10 minutes of exposure (fan blowing over the top of the beaker). As the E10 fuel evaporates it chills the air to the dew point and droplets form on the inside of the beaker, the droplets aggrgate and fall into the E10 gas and you can see the water contamination (milky appearance) starting at the 5 minutes mark (halfway). At the 10 minute mark the fuel has saturated completely and will start to separate taking with it the ethanol and reducing the octane of teh gasoline. And what is the Gulf Marine gasoline doing? Nothing, just sits there taking in NO WATER and evaporating at a much higher temperature which is above the dew point of the atmosphere.
