Premium gas provides no benefit to cars that use regular, AAA study finds – Los Angeles Times

Posted: Tuesday, September 20, 2016

Research by AAA has found that motorists wasted $2.1 billion in 2015 buying premium gasoline for cars that don’t require it.

Using tests designed to evaluate vehicle performance, fuel economy and emissions, AAA researchers said they found no benefit to using premium gasoline in a vehicle that only requires regular-grade fuel.

“Drivers see the ‘premium’ name at the pump and may assume the fuel is better for their vehicle,” said John Nielsen, AAA’s managing director of Automotive Engineering and Repair. “AAA cautions drivers that premium gasoline is higher octane, not higher quality, and urges drivers to follow the owner’s manual recommendations for their vehicle’s fuel.”

About 16.5 million U.S. drivers used premium gas despite the vehicle manufacturer’s recommendation that they use regular, AAA stated.
