Premium vs. Regular Gas

It is important to know the difference between premium and regular gas, as the type of fuel you use can affect performance and efficiency on the roads in and around East Greenwich. Knowing what type of gas to use in your vehicle will also help extend the life of your engine. In this guide from the service team at BMW of Warwick, we’ll compare premium gas vs. regular to help you determine which is the better choice for your vehicle. 

The Difference Between Premium and Regular Gas

Whether to choose regular gas vs. premium is something that has already been decided by your vehicle’s manufacturer. You’ll find the recommended type of gas in your owner’s manual. One difference between premium vs. regular gas that you’re sure to notice when you stop by your local Providence-area gas station is the price. There can be as much as a 20 to 40-cent difference between premium gas vs. regular, with premium being the more expensive of the two. Take a closer look at the differences between premium gas vs. regular gas:

Premium Gas

• Premium gas has an octane level of 91 or more. 
• Vehicles with a higher compression ratio in their engines, such as the models in the new BMW inventory at BMW of Warwick, will require premium gas to perform at peak levels. 
• Opting for regular gas vs. premium won’t necessarily harm the engine, but if you start to experience knocking from the engine, you should immediately switch back to premium. Engine knocking (or pre-ignition) can damage internal components and lead to expensive repair bills.

Regular Gas

• Regular gas usually has an octane rating of 87.
• Engines that have lower compression ratios are better equipped for regular unleaded gas as it burns faster than premium gas.
• Opting for premium gas vs. regular when your vehicle doesn’t require it won’t improve vehicle performance or longevity.
