Premium vs. Regular Gas

When you stop at gas stations around Orland Park, you’ll see the option for both premium and regular gas. So, what’s the difference between premium and regular gas? Both are petroleum-based formulas that fuel your car effectively, but premium gas has a higher octane rating. The octane rating refers to how well the formula resists engine knocking or pre-ignition, which can be a problem for performance and luxury cars. Find out what that means for you and your vehicle, and get more tips from The Garage at Bettenhausen in Tinley Park!

Premium vs. Regular Gas: What is Regular Gas?

What’s the difference between premium and regular gasoline? Let’s start with regular. Regular was once the only option available. And in the past, it even contained lead that would burn along with the gas! Now, you’ll only find “unleaded” gasoline around Oak Forest with an octane rating of around 87. 

Premium vs. Regular Gas: What is Premium Gas?

Premium gasoline is the more refined option of the two. It typically has an octane rating of around 90 or higher, which means it works better for engines with a higher compression ratio – like turbo and supercharged models. Any vehicle can use premium gas, but if your car doesn’t require it, you won’t see any additional performance benefits.

Should I Choose Regular or Premium Gas?

• Octane rating: If your car has a turbocharged or supercharged engine, using regular gas might cause engine knocking. This can damage the engine over time.
• Engine type: If your engine has a high compression ratio, this means it will perform at its best with premium gas. Check your owner’s manual to see what fuel type is recommended.
• Price: Premium is priced higher than regular gas – usually around 20 to 40 cents extra per gallon. If your car does not need premium, you can save yourself the extra money and stick with regular.
