Premium vs. Regular Gas: What’s the Difference?

If you’ve ever wondered what the difference is between premium and regular gasoline, then you’ll enjoy our online guide comparing premium vs. regular gasoline. Learning more about both can help you choose the right type for your vehicle. You can also learn more service tips and tricks with our service team at Hello Mazda of Valencia.

What is Premium Gasoline?

Premium gasoline has a higher octane level than regular gasoline. While both share a number of similarities, such as the fact that both are produced from crude oil and are combustible, they vary in octane level. Most premium gasoline has an octane level of 90 or above. This helps keep your engine cleaner, leading to less pollution.

What is Regular Unleaded Gasoline?

Regular gas, or unleaded gas, is the most common type of gasoline. This is better for the environment and better for your health than gasoline that contains lead. The octane level for regular gas is 87. 

The Difference Between Premium and Regular Gas

While the two options may seem similar, there are a few factors that set each apart: 

• Octane Rating: The higher the octane level, the less chance there is of engine knocking, which can damage your vehicle. Also called pre-ignition, this occurrence is less common with premium gasoline. 
• Engine Suitability: Regular unleaded gas burns faster than premium gas, which makes it more suited for engines that have low compression ratios. Engines with high compression ratios will benefit from premium gasoline. 
• Price: Premium gas can be as much as 20 to 40 cents more per gallon than regular unleaded gas, which can add up if you are frequently driving through Sylmar. 

Before deciding whether premium vs. regular gas is right for you, keep the following tips in mind:

• If your car does not require premium gas, it won’t boost the performance or the longevity of the vehicle. 
• If your vehicle requires premium gas, using regular gas typically will not harm the vehicle. If you hear knocking when you use regular unleaded gas, it is best to switch to premium gasoline. 
• It may be necessary to use premium gas in vehicles that utilize turbochargers.
