Regular Gas and Premium Gas Facts - Find Out if High Octane Fuel is Worth The Expense

If your car only recommends premium, the choice is yours. Like the Ford F-150 and Mazda MX-5 Miata, some cars require premium gas but don't want you to use them. AAA did some research and found that these cars had a small boost in performance and fuel economy when they ran on premium gas. Premium gas can help people who drive high-end or high-performance cars show off their cars' best features. But if your owner's manual says that "premium fuel is recommended," you can run your car on regular fuel without worrying about it. Commuters who need to get from Point A to Point B may not notice or care about how they drive. There is no right or wrong answer. Your car, your way.
