What is the Difference Between Regular and Premium Gas?

Filling Up Gas Tank



When you stop by a gas pump at San Antonio, you’re faced with a few choices. And if you’re trying to do what’s best for your new car, you might be wondering, “What is the difference between regular and premium gas?” While the answer will depend on a number of factors, we’ve got the information you need to make the best decision for your Aston Martin. Take a look at our regular vs. premium gas guide before you fuel up:

Regular Gasoline

Regular gasoline is the most common type of gas today. Both regular and premium are both made from crude oil, but the two differ in their octane level. Regular gasoline has an octane level of 87. Most vehicles will choose regular gasoline when they visit the station, and this versatile formulation is also well-suited to just about any vehicle.

Premium Gasoline

If regular gasoline is fine, why bother choosing premium? It goes back to octane level. While regular gasoline has an octane level of 87 on average, premium falls around 90. What does that mean for you? Premium gasoline has a higher octane level, which:

  • Prevents engine misfires or “knocks”
  • Increases fuel efficiency
  • Reduces harmful emissions

Not only does this lead to better performance, but many performance vehicles require premium gasoline to function at their peak, especially models with turbochargers. High-output engines have a higher compression ratio, which means a greater chance of preignition, and a premium formula leads to better performance overall. Check the owner’s manual to see if your Aston Martin requires premium.

Premium vs. Regular: Pros and Cons

It won’t harm your vehicle to use either regular or premium, but if you notice knocking, it’s better to move up to premium. Let’s go over the main differences:

  • Octane Rating: Higher octane levels lead to fewer engine knocks and better performance, which is where premium shines.
  • Engine Suitability: Regular gas is better suited for standard engines with low compression ratios, while engines with high compression ratio need premium.
  • Price: There’s usually a significant difference between regular vs. premium gas price, which can add up over a long Sugarland driver.

And lastly, can you mix premium and regular gas? It might not hurt your vehicle, but it won’t help. Keep it simple and stick to one formulation or the other.
