U.S. drivers waste billions paying for premium gas, AAA says

Does it pay to pay for premium gasoline?

Travel and leisure company AAA says it does not — and that U.S. drivers waste $2.1 billion in the past 12 months by paying for premium gas when the regular kind would do just was well.

For years, energy companies have tuned their marketing to the belief that, either occasionally or frequently, springing for the pricier stuff at the pump will be a treat for your car — a cleanse of sorts, or perhaps a performance boost that saves money in the long run.

For cars designed to run on regular gasoline, AAA could find no difference between premium and regular in terms of horsepower, fuel economy, or lower tailpipe emissions.
