When you pull into the gas station, do you know which type of gas you should really be pumping into your vehicle? Whether it’s an antique car or a more modern model you’re looking to fuel up, the car experts at Charlotte AutoFair in Charlotte, NC, want to make sure you know the differences between the types of gasoline offered.

Nearly every gas station offers three grades of gasoline: regular, mid-grade, and premium. Before you fill up your antique car with the cheap stuff and risk damaging it, make sure it is really the best option:

• Regular: Regular, unleaded gas has the lowest level of octane, and as such, it is usually about 15 to 20 cents cheaper per gallon than the premium grade. If your vehicle’s owner manual says regular gas is all that’s needed for your car, there is no need to upgrade.
• Mid-Grade: Mid-grade gas has a higher level of octane than regular fuel, which means your engine will have a higher resistance to knocking. While very few cars require the use of this gas, if you notice your engine pinging with regular gas, upgrading may help to stop it.
• Premium: Premium gas has the highest level of octane and is often required for luxury brands or some souped-up antique cars. Using premium gas will keep your engine running as efficiently as possible, as long as your car requires this type of gasoline.

The best way to keep your vehicle’s engine running smoothly is to use the type of gasoline the owner’s manual suggests.
