Should you pay more for premium gas?
(WDEF) – Should you spend the extra bucks to pump premium octane gas into your vehicle?
AAA has been putting engines to the test to find out.
Of course, some engines require premium grade gas (16%).
If that includes your vehicle, by all means, use the higher priced gas.
But what if the manufacturer simply “recommends” premium, or you have just heard that it will improve your engine’s performance.
AAA tested a Ford Mustang GT, Jeep Renegade, Mazda MX-5 Miata, Cadillac Escalade ESV, Audi A-3, and the Ford F150 XLT.
They put them through a combination of lab and on-road tests in everyday driving and under duress (towing, hauling cargo).
The premium gas was 91 octane or higher.
slight improved fuel economy (2.7% on average, Escalade improved 7.1%)
slight improved Horsepower (1.4 % on average, Mustang scored 3.2%)
But premium gas costs 20-25% more than regular.
“While many consumers assume premium gasoline will help their vehicle perform better because of the premium price, AAA’s research shows it is a waste of money for many,” said Stephanie Milani, Tennessee Public Affairs Director, AAA – The Auto Club Group.
“If your vehicle recommends regular gasoline, AAA research shows that there is no benefit to using premium gasoline; likewise, if your vehicle recommends, but does not require, premium fuel, the extra cost of premium fuel may not provide the fuel economy improvements driver are looking for.”
