When it comes to choosing gas at the pump, you may be tempted to upgrade your fuel for your car. But the reality is, if your car is less than 10 years old, there is no need to choose premium over regular fuel. In fact, going for the upgrade is likely a waste of money. Modern cars are designed to work with the lowest grade of gasoline available. Just double-check your car’s manual to see what grade of gas it calls for. In the long run, you’ll save money.
