Premium vs. Regular Gas

What type of gasoline should I use in my car? 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 Stamford. In this guide from the experts in the BMW of Greenwich service center, 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

More often than not, the decision between regular vs. premium gas has already been decided by your vehicle’s manufacturer. Your owner’s manual will have the recommended type of gas listed for your specific model. One difference between premium gas vs. regular you’re sure to notice at your local White Plains-area gas station is the price. There can be as much as a 20 to the 40-cent difference between the two with the premium being the more expensive option. Here are some other key differences you should look at when comparing premium gas vs. regular:

Premium Gas

• Premium gas typically has an octane level of 91 or more. 
• Vehicles with a higher compression ratio in their engine will benefit from premium gasoline. This is why BMW turbocharged engines require premium gas.
• 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 a hefty repair bill.

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.
