Marathon Oil Company is marketing a 90 and sometimes 91 AKI unleaded non-ethanol gasoline. This fuel perfectly suited for use with 87 octane auto fuel STCs at terminals in Florida, Michigan, or Georgia. Contact the terminals to find out where this "Recreational Fuel" is being distributed since not all Marathon stations are carrying it.
