Premium vs. Regular Gas

Many people ask us, "Will using premium gas make my car run better?"

Let's break it down and see what premium gasoline is all about.

Premium vs. Regular Gas

What is Premium Gasoline?

Gasoline comes in different grades, which are determined by their octane ratings. Regular gas has the lowest octane rating (86-87), while premium gas has the highest (91-93). Most gas stations also offer a mid-grade option that falls in between (88-90). The exact octane range can vary depending on where you live because of altitude differences.

Why Do Engines Need Different Octane Ratings?

Different engines need different octane ratings based on their design. For example, turbocharged engines usually require premium gas. There's a sticker on your gas tank filler lid that tells you the minimum octane rating your car's manufacturer recommends.

How to Choose the Right Gasoline for Your Car

To find out what kind of gasoline your engine needs, you can:

Check the Sticker: Look at the gas tank filler lid for the recommended octane rating.

Read the Owner’s Manual: It will tell you if it’s okay to use lower grades of gasoline. Some cars can adapt to lower grades, but they might lose some performance. Other engines might get damaged if you use a lower grade, which can lead to costly repairs.

Your car will run best on the grade of gasoline recommended by the manufacturer. Using a higher grade than recommended won’t give you any extra performance or better fuel economy.

Important Tips

Detergents in Gasoline: All grades of gasoline have detergents that help keep your engine clean. This means your engine will be protected no matter what grade of fuel you use.

Knocking or Pinging Sounds: If you hear knocking or pinging from your engine, take it seriously. It could mean your car needs a tune-up or other repairs. Bring your vehicle to David's Automotive Repair if you notice these sounds.
