In partnership with the Automobile Club of Southern California’s Automotive Research Center, AAA tested 87-octane (regular) and 93-octane (premium) gasoline in vehicles designed to operate on regular-grade fuel. Each vehicle was tested on a dynamometer, which is essentially a treadmill for cars that is designed to measure horsepower, fuel economy and tailpipe emissions when using both fuel types and a variety of driving conditions. The testing found no significant increases in any category, indicating there is no advantage to using premium gasoline when it’s not required for the vehicle. The auto club also surveyed U.S. drivers to understand what type of fuel their vehicles require and the frequency at which they upgrade to premium fuel. Results for U.S. drivers reveal: • Only 16 percent own a vehicle that requires premium fuel. • In the last year, 16.5 million unnecessarily used premium-grade gasoline in their vehicle at least once. • In the last year, drivers unnecessarily used premium gasoline in their vehicle more than 270 million times. Previous AAA research found that fuel quality varies significantly among gasoline retailers and that using a gasoline that meets TOP TIER standards can result in 19 times fewer engine deposits, increase vehicle performance and improve fuel economy. “Premium gasoline is higher octane, not higher quality. There isn’t a benefit to giving your vehicle a higher octane gas than what the owner’s manual recommends,” Walter said. Are you using the wrong octane?
