Mazda models that require premium fuel
Most Mazda models can run on regular gasoline, but some require premium fuel. Premium fuel is generally recommended for Mazda models with upgraded engines or trim levels. It's important to note that using the wrong grade of gasoline usually won't damage your vehicle. However, using lower-grade fuel in a car that requires premium fuel may result in faster wear and tear.

Mazda models that can use both regular and premium fuel
The type of fuel you use in your Mazda can have a significant impact on your vehicle's performance, fuel economy, and long-term health. Mazda owners need to be especially mindful of this because these vehicles come with a variety of engine types and specifications, each with its own fuel needs and recommendations.
Most Mazda models can run with regular gasoline, but some can also use premium fuel for a possible increase in horsepower and efficiency. The 2020 and 2021 Mazda3 Sedan, for example, can use regular fuel for all trim levels, but the 2021 2.5 Turbo and 2021 2.5 Turbo Premium Plus trims require premium fuel. Similarly, all models of the 2020 Mazda6 can use regular fuel, but the Grand Touring, Grand Touring Reserve, and Limited trims require premium fuel.
The Mazda CX-9, Mazda CX-30, and Mazda MX-5 Miata are other models that can use both regular and premium fuel. The Mazda CX-9 can run efficiently on unleaded or E10 fuel with a RON of 91 or higher, but it can also use premium unleaded with a RON of 95 or higher to optimise performance. The Mazda CX-30 can run on unleaded or E10 with 91 RON or higher, but the e-Skyactiv X 2.0 2.0L I4 petrol AWD model should use premium unleaded with 95 RON or higher. The Mazda MX-5 Miata has a minimum requirement of regular fuel, but Mazda recommends premium fuel.
When in doubt, you can always refer to your owner's manual, which will provide the most up-to-date and reliable information on your vehicle's fuel needs.

The impact of fuel on a Mazda's performance
The type of fuel used in a Mazda vehicle can have a significant impact on its performance, fuel economy, and long-term health. Mazda produces a range of vehicles with different engines, each with its own fuel requirements. For example, the Mazda CX-90 3.3L In-line 6-cylinder e-Skyactiv G model requires unleaded fuel with a minimum Research Octane Number (RON) of 95, while the e-Skyactiv D model requires diesel.
Most Mazda models do not require premium fuel, but some vehicles may only achieve their best performance using a higher octane fuel, typically with a minimum RON of 91. Premium fuel is advisable for cars with turbo engines, and it can also enhance the performance of other models. However, for cars that do not require or recommend premium fuel, using it will not provide any benefits, and regular fuel will work just fine.
Mazda's SKYACTIV technology and cylinder deactivation technology are designed to boost fuel efficiency and performance, and the company's PHEV systems combine the benefits of electric and traditional power. The electric vehicles are designed for zero-emission driving without compromising performance.
To ensure your Mazda runs at peak performance, regular maintenance is essential. Dirty air filters, clogged fuel injectors, and worn-out spark plugs can reduce engine efficiency and cause higher fuel consumption. High fuel consumption can be a frustrating and costly issue that may indicate potential mechanical problems.

The impact of fuel on a Mazda's long-term health
The type of fuel used in a Mazda car can have a significant impact on its long-term health. Mazda vehicles come with a variety of engine types and specifications, each with its own fuel needs and recommendations.
Most Mazda models can run on regular gasoline, but some upgraded models may require premium gas. For example, the 2021 Mazda3 Sedan with the 2.5 Turbo and 2.5 Turbo Premium Plus trim levels requires premium fuel. Similarly, the 2020 Mazda6 Grand Touring, Grand Touring Reserve, and Limited trims also require premium fuel.
The octane rating of the fuel is an important consideration. In most states, the octane rating for regular gas is 87, while premium gas has a higher rating of 91 or 93. A higher octane rating allows the fuel to withstand higher compression and reduces the chance of engine detonation occurring at the wrong time. Using a lower-grade fuel in a car that requires premium fuel may lead to increased wear and tear over time.
Mazda owners should refer to their owner's manual or look for a sticker inside their car's fuel door to determine the recommended fuel type and octane rating for their specific model. For example, the Mazda CX-9 is recommended to use unleaded or E10 fuels with a Research Octane Number (RON) of 91 or higher. The Mazda MX-30 M Hybrid can also run efficiently on unleaded or E10 fuel with a RON of 91 or higher.
In summary, the choice of fuel can have a significant impact on the long-term health of a Mazda vehicle. While most models can run on regular gasoline, certain upgraded models may require premium fuel. It is important for Mazda owners to refer to their owner's manual or seek guidance from a certified Mazda technician to ensure they are using the correct type of fuel and octane rating for their specific model.

How to check which fuel your Mazda needs
The type of fuel you use in your Mazda car is important. Using the right fuel can keep your car running smoothly and extend its lifespan. The wrong fuel can cause engine damage.
To check which fuel your Mazda needs, start by consulting the owner's manual. This will give you the most up-to-date and reliable information. If you don't have the manual, you can visit a Mazda service centre, which can advise on the best fuel for your vehicle.
You can also look inside your car's fuel door for a sticker that tells you if your car needs regular or premium gasoline. If you're in Australia, look for the RON (Research Octane Number) rating, which is a key measure for a petrol's octane rating. The higher the octane rating, the slower the fuel will combust. This is important for engines that require higher compression and heat endurance.
Most Mazda cars do not require premium fuel. However, some models, such as the Mazda CX-50, CX-5, and Mazda3 Sedan, will perform optimally with higher octane fuel. If your manual states that your Mazda's engine can take 87 octane fuel but will perform better with 91 or 93 octane, you can use either fuel type.
If you're unsure, you can try regular and premium gas to see if you notice a difference in performance. If you don't notice a difference, regular fuel is a safer choice.
