Do Audis Need Premium Gas? [Breakdown By Model] (2024)

When it comes to fueling your Audi, the question "Do Audis need premium gas?" often arises. As a renowned German automotive brand, Audi is known for high-end performance and unmatched AWD systems across models.

But does this advanced engineering mean you need to use premium gasoline?

It's a common assumption that Audis with turbochargers require premium fuel. However, the specific fuel requirement varies based on model and year.

While many turbocharged Audis are optimized for a premium to ensure peak performance and efficiency, some may operate fine on regular gasoline.

For example, turbocharged models like the A4 2.0 liter are designed to deliver optimal performance with premium fuel.

Using regular could result in diminished performance. On the other hand, some naturally aspirated Audis can run effectively on regular gas.

Ultimately, it's essential to consult your vehicle's manual to determine the right fuel type. This ensures your specific Audi model gets the fuel it needs for longevity and ideal operation.

Referencing your manual provides tailored guidance on whether your Audi needs premium gasoline.

Below, we have listed each Audi vehicle that has a turbo and needs premium fuel:

• Audi S6
• Audi RS 6 Avant
• Audi A4
• Audi A5
• Audi RS 3
• Audi S4
• Audi RS 7

In addition, we will highlight each Audi that requires premium fuel. Without further ado, let's get into it!

Audi Models That Thrive On Premium Fuel

Audi vehicles all come equipped with what is called direct injection technology.

This means that the gas and air mixture will be directly injected into the combustion chamber of each cylinder in the engine.

This will help the motor burn much more efficiently, which is why premium fuel is necessary.

Audi vehicles are made to run on premium gasoline because of their direct-injection technology and turbocharged engines.

Without using premium fuel, you can damage your Audi's engine and even cause severe damage if you don't fill up with regular gas when recommended.

Let's look at each Audi model that needs premium fuel and its features.

Audi S6

The Audi S6 is a fun sedan that offers a smooth ride and some sneaky power.

Older models have a 5.2-liter V10 engine that will get you from 0-60 in just 3.9 seconds. Newer models come equipped with a V8 engine. Some of the features of this vehicle include:

• Quattro all-wheel drive, check!
• 425 horsepower engine, check!
• Top speed of 155 mph, check!
• Premium fuel is necessary, yes!

Audi RS 6 Avant

The Audi RS 6 is a mighty wagon that can run on premium fuel.

What's New with 2023 Audi Models?

Audi's 2023 models continue the tradition of high performance and luxury the brand is known for.

One thing to note for Audi A3, A4, and A5 2023 models is their fuel recommendations.

Like their predecessors, these cars are optimized for premium gas to ensure the best performance and efficiency.

Using premium fuel with a higher octane rating helps prevent engine knocking and maintain the engine's longevity.

So, if you're thinking about getting a new 2023 Audi model, remember that filling up premium gas is the best choice for keeping your car running at its peak.

Octane Requirements Clarified

The term "octane rating" may seem intricate, but it straightforwardly assesses a fuel's capacity to withstand engine knocking or pinging, a phenomenon that can inflict long-term damage on your engine.

A fuel with a higher octane rating can endure more heat and pressure within the engine, deeming it more appropriate for high-performance vehicles, including various Audi models.

As you encounter different fuel options at gas stations, such as 87, 89, or 91 octane, keep in mind that a higher number indicates enhanced resistance to knocking.

While 91 octane fuel is a general recommendation for the majority of Audi vehicles, particularly those equipped with turbochargers, it is imperative to acknowledge that octane rating requirements can fluctuate.

Each Audi model and production year might have distinct octane needs to ensure optimal engine performance and longevity.

Always consult your vehicle's manual to determine the precise octane requirement for your specific Audi model, guaranteeing the maintenance of its peak performance and durability.

The Difference Between 87 and 91 Octane

If you're at the gas station and wondering whether to choose 87 or 91 octane for your Audi, here's a simple breakdown.

The numbers represent the fuel's octane rating, which measures its resistance to engine knocking.

Lower octane fuel like 87 is more likely to cause knocking, especially in high-performance cars like Audis.

On the other hand, 91 octane fuel is better suited for these vehicles, as it can handle higher temperatures and pressure in the engine without knocking.

So, it's generally a good idea for your Audi to use the higher octane option of 91 to protect your engine and ensure optimal performance.

FAQs

Is it OK to put regular gas in a premium car?

For most cars, you can get away with using regular gas.

This may work just fine for your car, but it's still best to use what your vehicle was designed for.

If you want to use regular gas, that's your call.

If you do happen to put regular gas in a premium car, drive the car until empty, and then at the next fill-up, put in premium gas!

What happens if I put regular gas in my Audi?

If you've accidentally put regular gas in your luxury Audi and have wondered what it did to the engine, we are here to tell you that it won't hurt your car!

As discussed above, run the Audi until the vehicle is completely out of gas and fill it back up with premium gas.

However, if it isn't a high-performance Audi, regular gas or premium gas is a complete preference.

Can I put 93 gas in my Audi?

You can put 93 Octane in your Audi if you want. It will work just as well and be more expensive than using premium-grade and regular-grade fuel.

However, keep in mind it isn't necessary to use 93 octane gas unless you have a high-performing Audi such as the R8.

This is simply because the other Audi models don't need this type of high-grade fuel to perform at their best.

Do all luxury cars require premium gas?

The answer to this question is no. Luxury cars and high-performance vehicles are designed to run on premium fuel, but you can certainly use regular if you choose!

Read what your owner's manual says about which octane type is suggested for your car's best results.

Most of the time, regular or premium fuel will not affect your performance, especially with newer, more advanced engines.

Of course, it's always best to follow the manufacturer's manual, but for most cars, it is safe to use either.

Can I use regular gas in a BMW?

It is best to use premium gas for most BMWs, but it isn't essential to the vehicle. However, you usually get better performance if you stick with premium fuel.

If you have a BMW requiring premium gas, do not put regular in the tank.

For most BMWs, this is easy to remember because those models usually say right on the trunk or fill-up door what octane level of fuel to use.

This octane number relates directly to your engine type and is listed on your owner's manual.

In some cases, the fuel type is even printed directly on the vehicle itself. Audi has similar labeling for their premium fuel recommendations.

Does premium gas really make a difference?

The short answer is yes; it does make a difference.

Whether you think it does or not, the EPA recommends that drivers use premium-grade fuel because of its increased octane rating.

The higher the octane rating, the better fuel burn and combustion efficiency are in your car.

Yes, you will spend more money on premium gas.

However, you will save a ton in the long run because your fuel efficiency and overall performance will improve your car, helping the engine run healthier.

Final Thoughts: Is Premium Fuel A Must?

It is important to always check the owner's manual for the best fuel for your Audi.

Audi offers several high-performing cars that will run at their best burning premium fuel.

It may be intriguing to buy the cheaper fuel, but premium fuel will be healthier for your Audi engine in the long run.
