PIERRE, S.D. (AP) - South Dakota Gov. Dennis Daugaard says he's directed the Department of Public Safety to implement an emergency rule allowing the sale of 85-octane gasoline with mandatory cautionary labels while permanent rules are debated and adopted.
The emergency rules will require South Dakota retailers who choose to sell 85-octane gas to label their fuel pumps to caution consumers to check their vehicle owner's manuals to determine what grade of motor fuel is appropriate.
Octane is a measure of fuel performance, with a higher octane level indicates better performance. Many manufacturers recommend a minimum of 87 octane fuel.
Daugaard says he's asked Attorney General Marty Jackley for an official opinion on whether 85-octane fuel may be sold legally in all or any part of South Dakota..
