What Kind of Gas Does a Maserati Take

Your Maserati deserves the best fuel to match its high-performance engine. Most models require premium unleaded gasoline with a minimum 91 octane rating to ensure optimal power, efficiency, and engine longevity.

When you slide behind the wheel of a Maserati, you’re not just driving a car—you’re commanding a masterpiece of Italian engineering. From the throaty growl of the exhaust to the lightning-fast acceleration, every component is tuned for performance, precision, and passion. But even the most powerful engine is only as good as the fuel it runs on. So, what kind of gas does a Maserati take? The answer isn’t just about filling up at any pump—it’s about understanding how fuel quality and octane rating directly affect your car’s performance, efficiency, and long-term health.

Maserati vehicles are built with high-performance engines that demand more from their fuel than your average sedan or SUV. These engines often feature turbocharging, high compression ratios, and advanced ignition systems—all of which require premium unleaded gasoline with a high octane rating. Using the wrong fuel can lead to engine knocking, reduced power, and even costly repairs down the road. Whether you own a sleek Ghibli, a thunderous Levante, or a track-ready MC20, using the correct fuel is essential to unlocking your Maserati’s full potential.

In this comprehensive guide, we’ll dive deep into the world of Maserati fuel requirements. We’ll explain why premium gas is non-negotiable, explore the science behind octane ratings, and offer practical tips for choosing the best fuel at the pump. You’ll also learn about ethanol blends, top-tier gasoline, and what to do if you accidentally fill up with the wrong fuel. By the end, you’ll have all the knowledge you need to keep your Maserati running like the high-performance machine it was designed to be.

Key Takeaways

• Premium unleaded gasoline is required: Maserati engines are high-compression and designed to run on premium fuel (91 octane or higher) for peak performance.
• Using lower octane fuel can cause engine knocking: Inferior fuel may lead to pre-ignition, reduced power, and potential long-term engine damage.
• Check your owner’s manual for exact specifications: Each Maserati model may have slightly different fuel requirements, so always refer to the manufacturer’s guidelines.
• Ethanol blends up to E10 are generally safe: Most Maseratis can handle gasoline with up to 10% ethanol, but avoid higher ethanol content like E15 or E85.
• Top-tier gasoline is recommended: Fuels from reputable brands with added detergents help keep your engine clean and running efficiently.
• Fuel quality impacts performance and longevity: Consistently using the right gas ensures smooth acceleration, better fuel economy, and fewer maintenance issues.
• Never use diesel or leaded fuel: These are incompatible with Maserati’s gasoline engines and can cause catastrophic damage.

Why Premium Gas Is a Must for Maserati

Let’s cut to the chase: Maserati engines are not built for regular unleaded gasoline. They’re engineered for power, precision, and performance—and that starts with the fuel. Most Maserati models, including the Quattroporte, Ghibli, Levante, and MC20, require premium unleaded gasoline with a minimum octane rating of 91. Some high-performance variants may even recommend 93 octane for optimal performance. But why is premium fuel so important?

The answer lies in the engine’s design. Maserati engines typically have high compression ratios—sometimes exceeding 10:1. In simple terms, this means the air-fuel mixture is squeezed into a much smaller space before ignition. Higher compression leads to more power and efficiency, but it also increases the risk of engine knocking (also known as pre-ignition). Knocking occurs when the fuel ignites too early in the combustion cycle, creating a knocking or pinging sound and potentially damaging internal components.

Premium gasoline has a higher octane rating, which means it’s more resistant to premature ignition. This allows the engine to operate at higher compression without knocking. When you use regular 87-octane fuel in a Maserati, the engine’s knock sensors detect the abnormal combustion and tell the engine control unit (ECU) to retard the ignition timing. While this protects the engine from damage, it also reduces power, throttle response, and fuel efficiency. Over time, consistently using low-octane fuel can lead to carbon buildup, reduced performance, and even engine wear.

For example, imagine driving your Maserati Levante on a winding mountain road. You press the accelerator to overtake another vehicle, expecting that instant surge of power. But if you’ve been using regular gas, the engine may feel sluggish and unresponsive. That’s because the ECU is holding back performance to protect the engine. With premium fuel, the engine can fire at the optimal moment, delivering the full force of its horsepower and torque.

The Science Behind Octane Ratings

To truly understand why premium gas matters, it helps to know what octane rating actually means. The octane rating measures a fuel’s ability to resist “knocking” or “pinging” during combustion. It’s not a measure of energy content—higher octane doesn’t mean more power in itself. Instead, it’s about stability under pressure.

There are two common methods for measuring octane: Research Octane Number (RON) and Motor Octane Number (MON). In the U.S., the number you see at the pump is the average of the two, known as the Anti-Knock Index (AKI) or (R+M)/2. For example, “93 octane” at a U.S. gas station means the fuel has an AKI of 93. In Europe, fuel is labeled by RON, so “95 RON” is roughly equivalent to 90–91 AKI.

Maserati recommends a minimum of 91 AKI (or 95 RON), which is why premium fuel is essential. Using 87-octane gas (the standard in the U.S.) simply doesn’t provide the resistance needed for high-compression engines. Think of it like trying to run a race in shoes that are too big—you might make it, but you won’t perform at your best.

Real-World Consequences of Using the Wrong Fuel

We’ve all been there—running low on gas, spotting a cheap station, and thinking, “Just this once.” But with a Maserati, that “just this once” could cost you. Using lower-octane fuel doesn’t always cause immediate damage, but it can lead to a cascade of issues over time.

One of the most common problems is engine knocking. While modern Maseratis have knock sensors that adjust timing to prevent damage, prolonged knocking can still cause carbon deposits to build up in the combustion chamber. These deposits can lead to hot spots, increased emissions, and reduced fuel efficiency. In severe cases, they can even cause pre-ignition that damages pistons or valves.

Another issue is reduced performance. As mentioned earlier, the ECU will retard ignition timing when it detects knocking. This means your Maserati won’t deliver the horsepower and torque it’s capable of. Acceleration will feel sluggish, and the engine may run hotter than normal. Over time, this can also increase wear on internal components like spark plugs and oxygen sensors.

There’s also the financial aspect. Premium gasoline is more expensive, but the cost of repairing engine damage from using the wrong fuel can be far greater. A single engine rebuild can cost thousands of dollars—far more than the difference in fuel prices over the life of the vehicle.

Understanding Maserati Fuel Requirements by Model

While most Maseratis share similar fuel requirements, it’s important to know that not all models are exactly the same. The manufacturer provides specific recommendations for each vehicle, and these can vary based on engine type, performance tuning, and regional fuel standards.

For example, the Maserati Ghibli with a 3.0L V6 twin-turbo engine requires premium unleaded gasoline with a minimum 91 octane. The same goes for the Quattroporte and Levante with similar engines. However, high-performance variants like the Ghibli Trofeo or Levante Trofeo, which feature more aggressive tuning and higher boost pressures, may benefit from 93-octane fuel for maximum performance.

The Maserati MC20, with its groundbreaking Nettuno V6 engine, is another case where fuel quality matters. This engine uses a pre-chamber combustion system inspired by Formula 1 technology, which demands precise fuel delivery and high-octane gasoline to function correctly. Maserati recommends 95 RON (91 AKI) or higher for the MC20, and using lower-octane fuel can disrupt the delicate combustion process.

Even the Maserati GranTurismo and GranCabrio, though older models, still require premium fuel. Their Ferrari-derived V8 and V12 engines are high-revving and high-compression, making them just as sensitive to fuel quality as newer models.

How to Find Your Maserati’s Exact Fuel Requirements

The best way to determine what kind of gas your Maserati takes is to consult the owner’s manual. This document provides detailed information about fuel type, octane rating, and any special recommendations. You can usually find it in the glove compartment or download a digital copy from the Maserati website.

Another reliable source is the fuel cap. Many Maseratis have a label on the inside of the fuel door that specifies the recommended fuel type. It might say something like “Premium Unleaded Gasoline Only – 91 Octane Minimum.” This is a quick and easy way to double-check before filling up.

If you’re unsure, you can also contact your local Maserati dealership or service center. Their technicians can provide guidance based on your specific model and year.

Regional Differences in Fuel Standards

Fuel standards vary by country, and this can affect what “premium” means in different regions. In the United States, premium gasoline is typically 91–93 AKI. In Europe, premium is often labeled as 95 RON or 98 RON. In some countries, like Mexico or parts of Asia, high-octane fuel may be less readily available or more expensive.

If you’re traveling internationally with your Maserati, it’s important to research local fuel options. In some cases, you may need to use additives or seek out specific stations that offer higher-octane fuel. Maserati vehicles are designed to adapt to different fuel qualities to some extent, but using the lowest-grade fuel available can still impact performance.

Ethanol Blends and Maserati: What You Need to Know

Ethanol is a renewable fuel made from corn, sugarcane, or other plant materials. It’s commonly blended with gasoline to reduce emissions and support domestic agriculture. In the U.S., most gasoline contains up to 10% ethanol, known as E10. Higher blends like E15 (15% ethanol) and E85 (up to 85% ethanol) are also available but are not recommended for most Maseratis.

The good news is that Maserati engines are generally compatible with E10 fuel. In fact, many modern vehicles are designed to run on ethanol blends without issue. However, ethanol has some drawbacks that are important to consider.

First, ethanol has less energy content than pure gasoline. This means E10 fuel provides slightly lower fuel economy—typically 3–4% less. For a high-performance car like a Maserati, this could mean fewer miles per gallon, especially during spirited driving.

Second, ethanol is hygroscopic, meaning it attracts moisture. Over time, this can lead to phase separation in the fuel tank, where water and ethanol separate from gasoline. This can cause corrosion, fuel system damage, and starting problems—especially in vehicles that aren’t driven frequently.

Third, ethanol can degrade certain rubber and plastic components in older fuel systems. While modern Maseratis are built with ethanol-resistant materials, older models may be more susceptible to damage.

Can You Use E15 or E85 in a Maserati?

The short answer is no. E15 and E85 are not approved for use in Maserati vehicles. These higher ethanol blends can cause serious damage to fuel lines, injectors, and engine components. E85, in particular, requires specialized flex-fuel engines designed to handle the corrosive nature of high ethanol content.

Using E15 or E85 in a Maserati could void your warranty and lead to costly repairs. If you accidentally fill up with E85, do not start the engine. Have the fuel tank drained immediately by a professional.

Tips for Using Ethanol-Blended Fuel

If you’re using E10 fuel (which is standard at most U.S. pumps), there’s no need to worry—just make sure it’s premium grade. To minimize the risks associated with ethanol, follow these tips:

– Use fuel stabilizer if your Maserati will be parked for more than a month.
– Fill up at reputable stations with high turnover to ensure fresh fuel.
– Avoid storing fuel in portable containers for long periods.
– Consider using a fuel additive designed to prevent moisture buildup.

Top-Tier Gasoline: Is It Worth It?

You may have noticed that some gas stations advertise “Top-Tier” gasoline. But what does that mean, and should you seek it out for your Maserati?

Top-Tier is a certification program created by a group of automakers—including BMW, General Motors, Honda, and Toyota—to promote higher fuel quality. To earn the Top-Tier label, gasoline must meet strict standards for detergent additives, which help keep fuel injectors, intake valves, and combustion chambers clean.

While Maserati is not an official member of the Top-Tier program, the benefits of using Top-Tier fuel apply to all high-performance engines. Cleaner fuel systems mean better fuel atomization, more efficient combustion, and reduced carbon buildup. Over time, this can improve performance, fuel economy, and engine longevity.

Which Gas Stations Offer Top-Tier Fuel?

Many major brands offer Top-Tier gasoline, including:

– Chevron
– Shell
– ExxonMobil
– Costco
– QuikTrip
– Sinclair

You can find a full list of Top-Tier retailers on the official website (toptiergas.com). When possible, choose a Top-Tier station that also offers high-octane premium fuel.

Should You Use Fuel Additives?

While Top-Tier gasoline contains sufficient detergents for most drivers, some Maserati owners choose to use aftermarket fuel additives for extra protection. Products like Techron or Sea Foam can help clean fuel injectors and remove carbon deposits.

However, additives should be used sparingly and only as needed. Overuse can lead to excessive cleaning, which may dislodge large chunks of carbon and clog fuel filters. Always follow the manufacturer’s instructions and consult your owner’s manual before using any additive.

What to Do If You Accidentally Use the Wrong Fuel

We’ve all made mistakes—maybe you were in a hurry, or the pump was mislabeled. If you accidentally fill your Maserati with regular 87-octane gas or a higher ethanol blend, don’t panic. Here’s what to do.

If You Haven’t Started the Engine

The best-case scenario is that you realize the mistake before starting the car. In this case, do not turn the key. Have the fuel tank drained by a professional technician. This will prevent any contaminated fuel from entering the engine.

If You’ve Driven a Short Distance

If you’ve only driven a few miles, the risk is lower—but still present. Modern Maseratis have sophisticated engine management systems that can compensate for lower-octane fuel to some extent. However, it’s still a good idea to have the fuel system checked.

Add a high-quality octane booster to the tank to raise the effective octane rating. Drive gently for the next few tanks, using only premium fuel. Monitor the engine for any signs of knocking or reduced performance.

If You’ve Driven Extensively on the Wrong Fuel

If you’ve driven a significant distance on regular gas, the engine may have experienced knocking or timing adjustments. In this case, schedule a diagnostic check with a Maserati service center. They can scan the ECU for error codes and inspect the engine for any damage.

In most cases, no permanent damage will occur—especially if you switch back to premium fuel quickly. But it’s always better to be safe than sorry.

Conclusion: Fuel Your Maserati Right

Your Maserati is more than just a car—it’s a symbol of performance, luxury, and Italian craftsmanship. To keep it running at its best, you need to treat it with the care it deserves. That starts with using the right fuel.

Premium unleaded gasoline with a minimum 91 octane rating is essential for all Maserati models. It ensures smooth combustion, maximum power, and long-term engine health. Avoid regular gas, high ethanol blends, and low-quality fuels. Instead, choose Top-Tier premium gasoline from reputable stations.

By following these guidelines, you’ll not only protect your investment but also enjoy the full thrill of driving a Maserati. After all, when you press the accelerator and hear that engine roar to life, you want to know it’s running on the best fuel possible.

So next time you pull up to the pump, remember: your Maserati doesn’t just take gas—it demands excellence.

Frequently Asked Questions

Can I use regular gas in my Maserati in an emergency?

While you can use regular 87-octane gas in a pinch, it’s not recommended. The engine may run, but performance will suffer, and long-term use can cause damage. Always switch back to premium fuel as soon as possible.

What happens if I use diesel in my Maserati?

Never use diesel in a Maserati. Diesel fuel will not ignite properly in a gasoline engine and can cause severe damage to fuel injectors, spark plugs, and the catalytic converter. Have the tank drained immediately if this happens.

Is 93-octane gas better than 91 for my Maserati?

Using 93-octane fuel can provide slightly better performance in high-compression or turbocharged engines, especially in hot weather or under heavy load. However, 91 octane is the minimum requirement and is sufficient for most driving conditions.

Can I use E85 flex-fuel in my Maserati?

No. Maserati vehicles are not designed for E85 or other high-ethanol blends. Using E85 can damage fuel system components and void your warranty. Stick to E10 or lower ethanol content.

Does using premium gas improve fuel economy?

Premium gas doesn’t inherently improve fuel economy, but it allows the engine to operate efficiently without timing adjustments. This can result in better mileage compared to using lower-octane fuel, which forces the ECU to reduce performance.

How often should I use a fuel additive in my Maserati?

Fuel additives are not needed regularly if you use Top-Tier gasoline. However, using a cleaner every 3,000 to 5,000 miles can help maintain fuel system health, especially if you drive in stop-and-go traffic or short trips.
