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

Gas pumps in a row


When you stop at your local Providence, RI gas station, you’ll have the choice of filling up with either premium or regular gas. What kind of gas does a MINI Cooper take? You can actually use either, but premium gasoline is recommended for MINI Cooper models. Learn more about the difference between premium and regular gas in this guide from the service team at MINI of Warwick.

Comparing Premium and Regular Gas

Let’s take a look at some of the differences between premium vs. regular gas:

  • Octane Rating: Premium gas typically has an octane level of 91 or more, while the octane level of regular unleaded gas is 87. High octane premium gas helps to keep your engine cleaner and leads to less pollution. There’s also less chance of harmful engine knocking (or pre-ignition) with premium gasoline than regular unleaded. 
  • Engine Suitability: Engines that have lower compression ratios are better equipped for regular unleaded gas as it burns faster than premium gas. Vehicles with a higher compression ratio in their engine will benefit from premium gasoline. 
  • Price: You’re sure to notice the price difference of premium gas vs. regular unleaded gas at the pumps around Newport, RI. There can be as much as a 20 to 40 cent difference between the two with the premium being the more expensive option.

Some other factors to consider when debating whether to fill up with premium or regular gasoline include:

  • Fueling up with premium gas when your vehicle doesn’t require it doesn’t improve vehicle performance or longevity.
  • Typically, vehicles that require premium gas won’t be harmed by using regular gas, however, it’s best to use premium gas if engine knocking is heard. 
  • Vehicles that utilize turbochargers may find it necessary to use premium gas. 

What Kind of Gas Does a MINI Cooper Take?

It is typically recommended that you use premium gas with an octane level of 91 or higher in your MINI Cooper. Of course, it is always best to check your owner’s manual to find out what kind of gas is right for your specific MINI Cooper model. Note that you should never use diesel fuel in your MINI as it can cause serious damage to the engine and fuel system. Here are some reasons to use premium gas in your MINI:

  • If you own a high-performance MINI Cooper, you’ll want to use premium gas in order for your engine to reach its peak performance levels.
  • Your MINI warranty may require that you use premium fuel.
  • If your MINI Cooper delivers better mileage with premium fuel, then you should feel free to use it. Many auto manufacturers claim that fuel efficiency is higher with premium vs. regular gas.
