Do Ford Ecoboost Engines Require Premium Fuel?

The technology of sustainable engines is an uprising, and the Ford Ecoboost engine launch seems like an incredible addition. This type of engine represents the perks of internal combustion technology. But it is mainly popular for its fuel efficiency, performance, and technology ensured by the premium fuel.  

Do Ford EcoBoost engines require premium fuel? Yes, it requires premium fuel when you want its peak performance. But if you’re satisfied with its regular performance, you may not require premium fuel. However, in this case, you may face issues like the reduced output of HP, knock, retarded timing, and overall lower performance. 

So, it’s important to learn about the effect of premium fuel to understand its necessity in a Ford EcoBoost engine. Let’s dive into this discussion as follows:  

Types of Ford Ecoboost Engines 

Types of Ford Ecoboost Engines 

There are three types of Ford EcoBoost engines. Which are as follows: 

Inline 3-cylinder

This is the first Ford EcoBoost engine type, also known as a straight 3-engine or inline-triple engine. It’s a 3-cylinder piston plate engine, and all three cylinders are set out in a single line along with the mutual crankshaft. 1.0L Fox, 1.5L Dragon, 1.1L Duratec Ti-VCT, etc., are some different versions of inline 3-cylinders. 

Inline 4-cylinder

Do Ford Ecoboost Engines Require Premium Fuel

Almost all cars and vehicles with four-cylinder engines set out their cylinders using the inline 4-cylinder layout. However, there’re a few exceptions, like Subaru and Porsche. 

But the majority of the manufacturers use horizontal flat-four layouts of this type. The versions of 2.0L Twin-Scroll and 2.3L are the Ford EcoBoost engines with this layout. 

V-type 6-cylinder

This type of Ford EcoBoost engine is arranged in a “V” shape. Mostly the six cylinder engine vehicles use this layout to set out the cylinders. 2.7L Nano (both the first and second generation), 3.0L Nano, 3.5L D35 first-generation, and 3.5L second generation, etc. 

Do Ford Ecoboost Engines Require Premium Fuel?

Ford EcoBoost engine manufacturers highly recommend using fuel ignition in this engine. The Ford EcoBoost engine series are pretty sensitive to their use of fuel because all the 2022 Ford mustang EcoBoost premium is turbocharged with premium gas power using direct injection of fuel. 

Hence, if you want to produce the highest rating for your engine power, you must use the highest available level of premium fuel in your engine. As we’ve mentioned earlier about the types of Ford EcoBoost engines, so here we’ll give you some insight on the fuel type those engines require: 

Premium Fuel for Inline 3-Cylinder

Ford Ecoboost Inline 3-cylinder engine requires a higher level of octane. Octane rated 87 is the regular gas, and octane rated 93 is the premium stuff. Both versions (1.0L Fox and 1.1L Duratec Ti-VCT) of Inline 3-cylinder require Octane 93. 

Octane 93 can lift the performance, reduce emission, knock, and other issues to most of the Inline 3-cylinder type engines. Only 1.5L Dragon is different because it is not particularly interested in taking Octane 93. So, it is better to try a lower-rated (octane 89) premium fuel with this engine. 

Premium Fuel for Inline 4-Cylinder

The recommended premium fuel for Inline 4-cylinder engine types is an octane rating higher than 87. It will improve the fuel economy and acceleration of your Ford EcoBoost engine. But if you run the engine with regular octane 87, it will run just fine. No enhancement in overall performance will be seen. 

Premium gas can’t make your vehicle faster, but it can make your vehicle an efficient one with less combustion, emission, energy, and issue. Therefore, it is better to go for octane 93 in the case of 2.0L and 2.3L Twin-Scroll (both versions of Inline 4-cylinder). 

Premium Fuel for V Type 6-Cylinder

For most V6 engine vehicles, premium fuel is recommended but not required. However, in the Ford EcoBoost V6 engine, octane 93 (premium fuel) is highly recommended. To reach its potential power and performance, using this specific premium fuel is a must to reach its potential power and performance. 

Is Premium Fuel Increase The Ford Ecoboost Engine Performance?

Yes, if the manufacturer recommends using premium fuel in the user manual of your Ford EcoBoost engine. Almost all the Ford EcoBoost engines suggest their users use premium fuel. Here are a few facts that cause premium fuel to increase the engine performance of the Ford EcoBoost engine:  

Less Heat and Combustion

Because premium fuels have a higher octane rating, the heat of gas resistance and combustion is lesser. Spontaneous combustion occurs due to the excessive heat inside the cylinders. 

No Knocking

Due to spontaneous combustion, a condition called “knocking” happens with the engine. But with premium fuel, your engine can resist that, and therefore there will be less chance of knocking. 

Reduced Emissions

Premium fuel can reduce CO2 emissions; therefore, your Ford vehicle engines will have fewer issues. Even the Ford EcoBoost engine manager recommends a premium fuel with a higher rating to provide the maximum output. 

Creation of Turbocharged Engine

To create turbocharged engines, premium fuel can produce higher heat and compression levels. When the Ford EcoBoost engine is turbocharged and using the premium fuel simultaneously, it can reach its potential energy level. 


A few common, typical questions about fuel usage in a Ford EcoBoost engine arise in people’s minds. Let’s guide you to the answers to those frequently asked questions to broaden your knowledge on our certain topic as follows: 

What’s the difference between premium fuel and regular fuel?

Regular fuel doesn’t have a satisfactory fuel rating, whereas the premium one has a higher number in rating. If your route is for the supreme fuel, you can get the highest octane rating. Octane as a fuel can resist “knock” and enhance your engine’s performance. Therefore, in terms of performance, premium fuel is far ahead of regular fuel.

Is it worth using premium fuel?

Yes, premium fuel is worth using because it can simultaneously offer fewer emissions and peak performance. In the case of most cars and vehicles, using premium grade fuel can improve mileage and performance, reduce the rate of CO2 emissions, etc. Premium fuel can ensure these in difficult conditions where your vehicle may need to work hard. 

What happens if I put premium gas in a regular car?

Putting premium gas in a regular car can go two ways. First, it can enhance engine performance and lessen engine emissions. Second, it can cause some serious damage internally. If the manufacturer refers to using premium fuel in a regular car in the manual. On the other hand, if there is no mention of using premium gas, the second case may happen. 


Ultimately, it boils down to your preference to choose between a regular fuel or premium fuel for your Ford EcoBoost engine. Regular fuel may cost less, but it’ll not offer premium performance. On the contrary, premium grade fuel will ensure your engine’s peak performance. 

Using premium fuel also keeps the engine away from emissions and issues. In comparison, regular fuel can have a few emissions. But neither of these two fuels will do any damage to your Ford engine. So, you should go for the one that can fill your priorities.
