SD inspectors now can check fuel octane levels

PIERRE (AP) -- South Dakota's Department of Public Safety says some of its inspectors now have devices to analyze the octane ratings of gasoline.

The agency recently said it is illegal to sell gas with an 85 octane level in South Dakota. An 85 octane level can cause an engine to run roughly. Motorists usually buy fuel with a minimum rating of 87.

Gov. Dennis Daugaard is using emergency state rules to allow sales of 85-octane gas. The Department of Public Safety is holding a hearing Friday on new fuel rules.

South Dakota's weights and measures director says the agency got two octane analyzers this week.

He says they're the size of a briefcase, and they'll allow inspectors to do spot checks of octane ratings.
