A new AAA study reveals why you shouldn't buy premium gas

The average price in MI on December 11 was 26.2% - $2.513 a gallon for regular and $3.171 for premium, according to. That means filling up a 20 gallon tank would cost an additional $10 when using premium fuel. The state average declined 2 cents during the past week.

AAA tested six vehicles: a 3.5L Ecoboost Ford F-150, 6.2L V8 Cadillac Escalade, 5.0L Ford Mustang V8; and four-cylinder engines in a 2.0L Mazda MX-5 Miata, 1.8L Audi A3 and 1.4L Jeep Renegade.

"Based on AAA's testing, vehicles that only recommend premium gasoline can't take full advantage of higher octane fuel and, as a result, the benefit that comes from upgrading to premium gasoline may not offset its high cost".

The answer: It makes a little difference in performance and fuel economy but not much. However, according to new research by AAA, using more expensive premium gas on vehicles that don't require it is just throwing money away.

You may think it's better than "Regular" gasoline because, well, it is called "Premium" and it costs more.

Ohio's gas prices were down 5.7 cents since last week's average. "AAA already proved that there is no benefit to using premium gasoline in cars created to run on regular".

In a study released a year ago, AAA found consumers wasted almost $2.1 billion fueling vehicles that neither recommended or required premium gasoline. Individual drivers - particularly if their driving style can be described as "spirited" - may find an improvement in vehicle driving performance for off-the-line acceleration, highway passing, hill-climbing when loaded with luggage, or towing a trailer; and may determine that their personal driving benefits from the use of premium gasoline.

The national average price for a gallon of gasoline dropped two cents on the week to $2.46, according to a new report Monday from AAA. Higher levels of octane allow engines to run at higher compression ratios without knocking. The story could obviously be different in vehicles that require premium, but in many cases these are high-performance cars where owners are happy to pay up for a boost in horsepower.
