What is Premium Gasoline?

Both premium and regular gas share several factors. They are both produced from crude oil, and both types of gas are combustible. But, when comparing premium vs. regular gas, you’ll find they have different octane levels. Typically, premium gasoline around South Riding will have an octane level at or above 90. That is why premium gasoline aids in keeping your engine cleaner than regular gas, which helps reduce air pollution.

What is Unleaded Gasoline?

Unleaded gasoline is the most common gas type in the Centerville area. It is better for our health and the environment than gasoline which contains lead. Its octane rating is usually about 87 but standards vary around the country. The octane level rates its combustion level.

The Difference Between Premium vs. Regular Gas

There are a few things that vary between premium gas vs. regular. Learn more about the difference between premium vs. regular gas below.

  • Octane Rating: The higher the octane level in gasoline, the less chance there is of engine knocking, which can cause damage to your vehicle. This is why most Mercedes-Benz models require premium gasoline.
  • Engine Suitability: Regular unleaded gasoline burns faster than premium, so it’s more suited for engines with low compression ratios.
  • Price: Premium vs. regular gas prices can vary as much as 20 to 40 cents more per gallon than regular at Ashburn gas pumps.

Keep the following tips in mind when deciding between premium vs. regular gas:

  • If your car doesn’t require premium gas, using it probably won’t boost performance or the lifespan of your car.
  • If your vehicle requires premium vs. regular gas, using regular will not usually harm your vehicle, but it is best to follow the auto manufacturer’s recommendations. If you hear knocking when you use regular gas, the service team at Mercedes-Benz of Chantilly recommends switching to premium gasoline to see if the knocking stops.
  • Premium gas vs. regular is typically best for vehicles with a turbocharged engine.
