COLUMBUS, Ohio – Ohio state legislators have proposed legislation to make sure customers are filling up with the right gasoline by giving county auditors authority to test octane levels at the pump for accuracy, reports the Associated Press.

“When you pump that 93 octane gas into your car, you have no way of knowing if it's 93, 92 or 87," Rep. William Healy II (D-Canton) told the news source, adding, “We need to make sure consumers are getting what they paid for.”

Rep. Healy was joined by five Republicans and 15 Democrats of the Ohio State House to introduce the measure. He noted that nearly 6 billion gallons of gasoline are sold each year in the state.

The AP writes that Summit County is the only county in the state that gives an auditor the authority to check octane levels and shut down dispensers that register “low-quality fuel.”

Franklin County Auditor Joe Testa told the news source he has been testing fuel quality levels in the Columbus area since 2001. Since then, he says that failure rates have dropped from 15 percent in 2001 to about 3 percent to 5 percent each year since.

Testa says that if the bill becomes law, the cost to counties would likely be minimal because auditors already check dispensers for accuracy.

Meanwhile, Ohio Petroleum Marketers and Convenience Store Association General Counsel Jennifer Rhoads told the AP that the proposed legislation is “unnecessary” because many oil companies already conduct their own checks on fuel octane levels and must adhere to strict federal fuel standards.
