Amy called home to ask if she could fill up the car with premium gas--they were out of regular and mid-grade gas at the pumps. The station was offering premium for the same price. Norm told her to go ahead and give the car "a treat." But according to one Honda dealer's website, your car doesn't need to be "treated" to premium gas if it's running smoothly. If your manual recommends using a higher grade but higher octane gas is not required, and your car or truck less than ten years old, you might be able to save money by using regular gas.
The dealership's online article explains:
Virtually every expert – even those from oil companies and auto manufacturers – say that using Regular will not harm engines, but you’ll probably not get the ‘advertised’ performance. In other words, you may add a second to the zero-to-100 km time a reviewer said you should expect from your car. Again, using Regular gas will not damage the modern engines of most of today’s cars.
