Premium vs. Regular Gas: Know the Difference

Filling up gas tank with premium 91 octane gasoline
When fueling up at gas stations in Virden, have you ever wondered about the difference between premium and regular gas? If so, you’ve come to the right place! Join Virden Mainline Motors as we compare premium vs. regular gas to help you determine what is best suited for your specific Buick, Chevrolet, GMC vehicle.

What Is Premium Gasoline?

Premium and regular gasoline actually share a number of qualities, including that they’re both produced from crude oil and both are combustible. Their biggest difference lies in the octane level, which indicates how well it combats inappropriate fuel combustion. Most premium gas has an octane level of 90 or above. Why do some Birtle drivers choose premium over regular? It helps keep your engine cleaner, leading to less pollution and better fuel-efficiency.

What Is Regular Unleaded Gasoline?

The most common type of gas, regular unleaded gasoline is the required fuel type for most vehicles on Oak Lake streets. It is more environmentally-friendly and better for your health than gas that contains lead. The octane rating for regular unleaded gas is 87.

The Difference Between Premium and Regular Gas

While the two options may seem similar, there are a few factors that set premium and regular gas apart:

  • Octane Rating: The higher the octane level, the lesser the chance of engine knocking, which can damage your vehicle. Engine knocking is sometimes called pre-ignition and is less common when using premium gas.
  • Engine Suitability: Regular unleaded gas burns quicker than premium, making it better suited for engines with low compression ratios. Engines that have high compression ratios are better suited to premium gas.
  • Price: While at the pump, you’ve probably noticed that premium gas is more expensive than regular. It can be up to 20 – 40 cents more per litre, which can add up if you do a lot of driving in Elkhorn.

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

  • If your vehicle doesn’t require premium gas, it will not boost the performance or lifespan of your vehicle.
  • If your vehicle does require premium gas, it shouldn’t do any harm if you use regular gas. However, if you do use regular unleaded and you start to hear knocking, you should make the switch to premium.
  • Vehicles with turbochargers may require premium gas – you can confirm this with your owner’s manual.
