What is Premium Gasoline? 

When it comes to premium vs. regular gas, you’ll find that, while they’re both produced from combustible crude oils, premium gas is cleaner. It has a higher octane level, usually above 90, which allows it to produce less pollution and help your engine run more efficiently on Lansdale streets. 

What is Regular Unleaded Gasoline? 

As for regular unleaded gas, it has a lower octane level than premium at around 87. It’s also better for the environment than leaded gas. Finally, it’s the most common fuel available at Chalfont gas stations and can be used by the majority of engines without damaging your engine. 

The Difference Between Premium and Regular Gas

Let’s compare premium vs. regular gas in greater detail. Here are there key differences: 

  • Octane Rating: Premium has a higher octane level, is more efficient, and less likely to “knock” or “pre-ignite” your engine, which can cause damage. 
  • Engine Suitability: Regular unleaded gas is quicker burning, which allows it to work with the majority of engines that have low compression ratios. Engines with high compression ratios require premium gas. Usually, only sports cars or other high performance vehicles require premium. 
  • Price: Regular gas is much more affordable—usually 20 to 40 cents less per gallon.
