Is premium gas the same as regular gas?

True or false—premium gas is the same as regular gas

Is premium gas is the same as regular gas? Ramon, Accelerate Auto Repair’s Fixed Operations Manager, has the answers. According to Ramon, premium gas has a higher octane than regular gas, making it a better option for high-performance engines. In most states, regular gas is rated at 87 octane, while premium gas is typically rated higher—at 91 or 93. Plus, premium gas may also contain additional or higher-quality additives in comparison to regular gas. However, most drivers’ cars will run perfectly fine on regular gas, and premium gas is not necessary. Here’s why!

Premium gas vs. regular gas—here's what you need to know

In luxury and performance vehicles with turbochargers or high-compression engines, premium gas has a higher resistance to engine knock, so drivers can utilize their horsepower more smoothly. Premium gas has also been known to increase fuel efficiency, which allows for better gas mileage while lowering emissions.

These benefits are primarily seen in vehicles that truly require premium gas and not necessarily in most other vehicles. Not sure whether or not you need premium gas? Your owner’s manual is a good place to start your research. See what your manufacturer recommends for your specific car make and model. 

If your owner’s manual says your vehicle doesn’t require premium gas, then don’t pay for something you don’t need! Premium gasoline costs approximately fifty cents more/gallon than regular gas and has no positive or negative effect on cars, trucks, or SUVs that can’t take advantage of it.

If you’re not sure if your car needs premium gas vs. regular gas, feel free to bring it in to Accelerate Auto Repair, and we’ll determine what makes the most sense for your vehicle.

Premium gas varies from state to state

Don’t forget! The premium gas designation varies from state to state. Pay attention when getting gas across state lines. One state may require a minimum octane rating of 91 to be considered premium gasoline, while another may only require 89 to be considered premium. Gas stations in the U.S. generally offer three octane grades—regular (usually 87 octane), mid-grade (usually 89 octane), and premium (usually 91 or 93 octane). Check the sticker on the pump to know which you are getting.
