Industries Oppose Making 85 Octane Gas Legal in SD

Gas Pump Handle


SIOUX FALLS, S.D. (AP) – The automobile, ethanol and small engine manufacturing industries are opposing an effort that will make the sale of 85 octane gasoline legal in South Dakota.
Most modern vehicle engines require a minimum octane level of 87. Auto Alliance spokesman Dan Gage tells the Argus Leader that running lower-quality fuels reduces engine performance and can lead to damage.
Refiners dispute that. And 85 octane gas has commonly been used as a fuel for higher altitudes in western South Dakota.
The state Department of Public Safety is writing rules to clarify the legal status of 85 octane fuel and specify how it must be labeled. Government officials say mislabeled fuel has been found in several cities in eastern South Dakota. Suppliers say a constant threat of fuel shortages is the reason.
