Having a sports car is something everyone dreams of. But one of the most important questions that people ask is – Why do sports cars need premium gas? Premium gas is always better than regular gas because it has a higher octane rating. This octane is, basically, the ability of the fuel for resisting the ‘knock’ which is the loud noise that comes out when the mixture of gas is incorrect. 

Hence, the answer is – YES! Some of the sports cars are designed in such a way that they will need premium gas. This high octane rating gas comes with a mix of hydrocarbons with lower combustibility than the ones present in regular gases and fuels. 

Why do sports cars need premium gas?

One of the leading causes of the engine knock is pre-ignition. Due to this knock, the engine can often produce an erratic rattling sound or a pinging sound from the hood of your car.

As mentioned above the premium gas comes with low combustion and it prevents the pre-ignition which happens even before you can start the engine. The pre-ignition can potentially damage your engine or reduce the efficiency over time. 

As sports cars are premium expensive cars, you need to make sure that you are using the best gas for them. Premium gas can protect your car’s engine from getting damaged or being inefficient over time.

Many studies have proved that using premium gas in the sports car can significantly improve performance. But you can only see the difference if your sports car comes with a high compression engine.

When a sports car comes with a high compression engine, it can get more power. With more power, the chance of detonation increases before the ignition of spark plugs (don’t want spark plugs? Here are some trucks that don’t have them).

Hence, luxury or sports cars need premium gas as that does not combust efficiently under pressure. The premium gases are available in different Octane varieties, such as Octane 95, Octane 100, and Octane 102. The higher the octane, the better the performance of the engine and you will get a better horsepower. 

Why premium gas is better?

Now that you know why you must use premium gas for sports cars, it is important to know the benefits of using premium gas.

Besides the market hype about the premium gas, there are some amazing benefits that it comes with. Here are some of the best benefits of using the premium gas in your sports car:

  • Superior quality can be good for the engine of your sports car
  • Comes with high resistance power for knocking that makes your car engine run more efficiently
  • High octane premium gas comes with fewer pollutants 
  • Can increase the performance of the engine of your sports car significantly, especially the torque and power output
  • Can effectively prevent any damage to your car’s mechanical components due to pre-ignition

Should you use premium gas for your sports car?

While some sports cars need premium gas to run, some of them are even designed to run on regular gases. In this situation, you must be wondering what you should use.

Well, you have to take a look at the user’s manual presented to you when you bought the car. The manufacturer will tell you if your car ‘requires’ premium gas or not. If the manufacturer uses the word ‘recommends’ for the premium gas, even then, it is better to use the premium gas. 

Often luxury sports cars need premium gas for running. Using a regular gas instead of the premium one can adversely affect the engine. It can even affect the result of the engine outputs, such as power and torque. According to a report, the performance of the sports car can drop anywhere between 5 percent and 10 percent if you don’t use premium gas. 

Why is premium gas so much money?

Premium gas is often significantly more expensive than regular gas, leading many drivers to wonder why they should bother paying the extra money.

There are a few reasons for the price difference.

First, premium gas typically contains a higher octane rating than regular gas, which means it can better resist engine knock.

Second, premium gas is often cleaner-burning than regular gas, helping to reduce emissions and improve fuel economy.

Finally, premium gas is typically blended with other ingredients that can help to improve engine performance.

For those looking to get the most out of their vehicle, premium gas is definitely worth the extra cost.

What happens if you put regular gas in a sports car?

The engine will likely run a bit rougher than usual, and it may knock or ping. In addition, the engine may run hotter than normal, which could lead to increased wear and tear. As a result, it’s always best to use premium gas in a sports car to ensure optimal performance.

If you use the wrong gas in some sports cars, it can void your warranty, leaving you with the repairs needed!

What happens if you use premium gas in a car that only needs regular gas?

Premium gas is a higher octane gas that some carmakers recommend or require for their vehicles. Premium gas typically costs more per gallon than regular gas.

Using premium gas in a car that doesn’t require it will generally not affect the car’s performance or fuel economy.

The car’s engine will run a little cooler on premium gas due to the higher octane level.

However, if you’re concerned about your car’s performance, it’s always best to consult your owner’s manual or speak to a qualified mechanic.


Most sports cars are designed to run only with premium gas. It is quite evident from the above explanations why your sports car needs premium gas with high octane.

If you have already bought a sports car or planning to buy one, then make sure to do a bit of research on what type of gas it requires for the best performance.

Even if you are not looking for a performance, you must choose premium gas for better longevity and durability of the engine of your sports car.
