Isobutanol Available in 2017

Just Announced: Isobutanol to be available to marinas summer of 2017.

Better for your boat. Better for the environment.

In an effort to find relief from the challenges to fuel containing Ethanol, MTAM has been working to substitute Isobutanol for Ethanol in Maryland. This required MTAM to send a formal request for an exemption to the regulation that had prevented the splash blending of Isobutanol with fuel. The request was GRANTED! For the near future, this fuel will be available only to on-water fuel facilities, which we are hoping will give an advantage this boating season. IF YOU SELL FUEL, ask your provider about using Isobutanol this season!

We thank GEVO a manufacturer of Isobutanol for their work on this and our thanks to Delegate Herb McMillan (AACounty) for his leadership.

See Fact Sheet

Isobutanol is compatible with small engines and solves the concerns that many boaters have with ethanol blended gasoline. Here are the advantages of Marine Fuel with Isobutanol:

  • 30% higher energy content than ethanol
  • Elimination of phase separation issues
  • Reduced emissions and increased octane
  • No water solubility issues
  • Made from renewable resources

Tested and proven by the National Marine Manufacturers Association (NMMA) in collaboration with the Department of Energy and Argonne National Laboratory, Isobutanol is fully compatible with marine products and other small engines. Performance validated with Mercury, Evinrude, Johnson, Sea Doo, Volvo Penta, Honda, Yamaha, and Indmar. The manufacturers acknowledge the advantages over ethanol.

See Fact Sheet

Isobutanol has UL approval for use in fuel pumps and dispensers.  It is compatible with the standard materials of construction that are used for storage and dispensing of ethanol blends as well as clear gasoline so if you have a UL approved pump and dispenser, Isobutanol will have no issues.  For good order’s sake it is always good practice to inspect equipment, piping, and tanks for leaks so prior to switching to an Isobutanol blend, do a good inspection of your system.

Although an internal combustion engine will have no problems running with mixtures of E10 and i12.5 as demonstrated by NMMA testing, the EPA has not yet approved comingling of E10 and i12.5 in storage tanks or dispensers.  So prior to loading storage tanks with i12.5, the tank should be emptied to the lowest level possible.

Labeling of the dispenser is very similar to requirements for E10, Gevo will provide labels required by the Weights and Measures Department of the State of operation of the retailer or marina.
