Marathon Oil Co. is marketing a 90 octane unleaded non-ethanol gasoline as a recreational fuel for boats. We believe this fuel to be perfectly suited for use with 87 octane auto fuel STCs. In some locations it is one octane point higher, 91 octane. 91 octane is suitable for use with all auto fuel STCs.
90 or 91 octane may be available at the following bulk product terminals:
- Ft Lauderdale-Eisenhower
- Ft Lauderdale-Spangler
- River Rouge, Mich.
- Detroit, Mich.
- Romulus, Mich.
- Doraville, Ga.
- Powder Springs, Ga.
Pilots living near those areas should contact the terminals to find out where this “recreational fuel” is being distributed since not all Marathon stations are carrying it.
Be advised that not all gasoline service station pumps are labeled as to ethanol content. The ethanol lobby considered pump labeling to be “discriminatory” and lobbied successfully for changes to federal pump labeling laws. That’s why pumps are labeled as to ethanol content only if state law continues to require it.

The GAfuels Blog is written by three private pilots concerned about the future availability of fuels for piston-engine aircraft. They are:
- Dean Billing (Sisters, Ore.) – an expert on autogas and ethanol
- Kent Misegades (Cary, N.C.) – an aerospace engineer and aviation journalist
- Todd Petersen (Minden, Neb.) – former aerial applicator and owner of more than 150 Mogas STCs for aircraft
For a list of airports that have ethanol-free fuel and those no longer pumping it, compiled by the author’s, follow this link.
Where in NE Fl/ SE GA can 91 octane fuel be bought?
