When it comes to filling up your car, you may have wondered whether you should be using premium gas or if regular fuel is sufficient. The main difference between the two lies in their octane ratings. Premium gas generally has a higher octane level, making it more resistant to engine knocking. However, in Chicago, most vehicles do just fine with regular gasoline, unless specified otherwise in your car’s manual.
Insure on the Spot is here to help you understand the benefits and costs of each fuel type. Call 773-202-5060 for expert advice today.
What is the Octane Difference Between Premium and Regular Gas?
The key difference between premium and regular gas is the octane rating.
- Regular Gas: Typically has an octane rating of 87.
- Premium Gas: Usually has an octane rating of 91 or higher.
Higher octane levels help fuel resist premature ignition (also called “knocking”), which can damage your engine over time. This is particularly important for high-performance or high-compression engines, often found in sports cars and luxury vehicles. Understanding this difference can help you decide if your vehicle truly requires premium fuel for optimal performance. Using premium fuel in an engine that doesn’t require it may not provide any noticeable benefit and can be an unnecessary expense. Always refer to your vehicle’s manual to determine the type of fuel recommended for your specific engine.
Should You Use Premium Gas in Your Car?
Whether you need to use premium gas depends on your vehicle’s requirements.
- Required by Manufacturer: Some vehicles, especially those with turbocharged or high-compression engines, need premium gas to avoid engine knocking.
- Unnecessary for Most Vehicles: Most Chicago drivers do not need to use premium gas. If your car’s manual doesn’t specifically require premium, using regular gasoline won’t harm your engine or hurt your performance.
By following your car manufacturer’s guidelines, you can avoid unnecessary costs without sacrificing engine performance. Regular gas is sufficient for most vehicles on the road today, making it the more economical choice for everyday drivers.
The Cost of Premium vs Regular Gas
In Illinois, premium gas typically costs more than regular gas. However, the price difference might not justify the expense unless your car requires premium. Here’s why:
- Cost Difference: Premium gas can be 20 to 40 cents more per gallon than regular gas.
- Fuel Efficiency: While premium fuel may provide better performance for certain engines, using it in a vehicle that doesn’t require it likely won’t improve fuel economy or engine longevity.
For most drivers, the extra cost of premium gas is not necessary, and opting for regular gas will save money without compromising vehicle performance. If you’re unsure about which type of fuel your car needs, consult your vehicle’s owner manual or speak to an expert.
