How many miles per gallon does the 1.5 L EcoBoost get?

The 1.5 L EcoBoost is a compact turbocharged engine used in several Ford models, so there isn’t a single miles-per-gallon figure. In U.S. models, typical combined fuel economy sits around 29–30 mpg in common configurations, with a range from the high 20s to the low 30s depending on the exact vehicle, drivetrain, and transmission. This overview reflects EPA-tested estimates and real-world variability as of model years up to 2024.

Typical fuel economy by model and configuration

These are representative EPA ranges for widely available 1.5 L EcoBoost-powered Ford models in the United States. Values shown reflect common drivetrains (front-wheel drive with an automatic transmission). Real-world results vary with driving conditions and options.

• Escape (1.5 L EcoBoost, FWD with an 8‑speed automatic): about 27–30 mpg city and 33–34 mpg highway, roughly 29–30 mpg combined.


• Focus (1.5 L EcoBoost, various configurations): typically around 32–34 mpg combined, depending on transmission and trim.

Note: These figures are approximate EPA ranges and can differ by year, market, and exact drivetrain. For the precise rating of your specific vehicle, check the current EPA estimates or the vehicle’s window sticker.

Model-specific notes

What factors affect mpg and how to maximize it

Several factors influence the mpg you actually experience with a 1.5 L EcoBoost. Beyond the engine itself, the car’s drivetrain, tires, and how you drive play major roles. The following list highlights key influences and practical tips.

• Drivetrain and transmission: Front-wheel drive with a modern automatic tends to yield better efficiency than all-wheel drive or older transmissions.


• Tire pressure and condition: Under-inflated tires or worn tread increase rolling resistance and reduce fuel economy.


• Driving style: Smooth acceleration, steady speeds, and cruise control on highways typically improve mpg compared with aggressive, stop-and-go driving.


• Load and aerodynamics: Heavier payloads and roof racks increase air resistance and lowers mpg.


• Maintenance: Regular oil changes, clean air filters, and timely fuel-system service help preserve expected efficiency.

Keeping these factors in mind can help you approach the EPA estimates more closely in daily use.

Where to verify current ratings

EPA fuel-economy numbers are updated annually and differ by model year and configuration. For the exact, up-to-date ratings for your vehicle, consult the official database: fueleconomy.gov.

Summary

The Ford 1.5 L EcoBoost’s mpg varies by model year, drivetrain, and configuration, but most U.S. buyers encounter roughly 29–30 mpg combined in common setups, with the potential for a bit higher or lower depending on specifics. For precise numbers, always check the latest EPA ratings or the manufacturer’s window sticker for your exact vehicle.

Is a 1.5 l engine fuel-efficient?

Although 1.5-litre engines are relatively more fuel-efficient with modern technology, they generally only provide between 15 and 20 km/l. Performance Characteristics: Cars with 1 litre vs 1.5 litre engines perform differently on the road.

What is the gas mileage on the 1.5 L EcoBoost?

27 mpg city and 34 mpg highway
1.5L EcoBoost Engine – Delivers up to 27 mpg city and 34 mpg highway with front-wheel drive. 2.5L Hybrid Engine – Provides up to 42 mpg city and 36 mpg highway, making it a Ford hybrid MPG leader 2025.

Is the Ford 1.5 EcoBoost engine any good?

The 1.5L EcoBoost is generally considered a good engine, offering a strong balance of power and fuel efficiency, but it has had a significant reliability issue in some older models. While newer versions have addressed many of the problems, potential buyers should be aware of the coolant intrusion issue in earlier models (like the 2017-2019 Escape) and the need for proper maintenance.

Pros

• Balanced performance: It delivers a good mix of responsive power and fuel economy, suitable for everyday driving and small SUVs. 
• Compact design: Its small size makes it suitable for a variety of Ford models. 
• Improved reliability in newer models: Ford has addressed early issues, making newer versions more reliable. 

Cons and potential issues

• Coolant intrusion: Some early models (especially 2017-2019 Escapes and Fusions) had a problem with coolant leaking into the engine cylinders, which can cause serious damage. Ford has issued updated designs to address this in newer models. 
• Wet timing belt: This engine uses a belt-driven oil pump system that runs inside the engine, which requires diligent maintenance. Neglecting the service schedule can lead to costly repairs. 
• Maintenance is crucial: As with many modern engines, proper maintenance is key to long-term reliability. Neglecting it can lead to expensive repairs.

Recommendations

• If buying a new model: Newer 1.5L EcoBoost engines have addressed many of the previous issues and are generally considered a good choice with proper maintenance. 
• If buying a used model: Thoroughly check the service history. For models with the coolant intrusion issue, ensure the affected engine block has been replaced with an updated version. 
• Be proactive with maintenance: Follow the factory-recommended service schedule closely to avoid problems, especially concerning the oil and belt-driven systems. 

How long will the 1.5 L EcoBoost engine last?

A 1.5L EcoBoost engine can last between 150,000 and 200,000 miles on average with proper maintenance, though some owners have reported reaching over 200,000 miles. A key factor in its longevity is addressing potential issues like the known coolant intrusion and fuel injector problems, which are less likely in newer models that combine direct and port fuel injection.

Factors that influence lifespan

• Maintenance: Consistent oil changes and other scheduled maintenance are crucial for longevity. 
• Coolant leaks: A known issue is coolant intrusion, which can be costly to fix. Newer models may be less prone to this problem due to design changes. 
• Carbon buildup: Direct injection can cause carbon buildup, but this is less of an issue in newer engines that use a combination of direct and port injection. 
• Fuel injectors: Fuel injector issues can occur after 80,000 to 100,000 miles due to normal wear and tear. Ford has offered a customer service program to address these issues in certain model years. 

Tips for maximizing engine life

• Follow the recommended maintenance schedule in your owner's manual. 
• Address any warning signs or issues promptly. 
• Consider having your coolant checked and replaced according to the maintenance schedule to prevent issues associated with coolant intrusion. 
• Be aware of recalls and service programs, like the one for fuel injectors, and have them addressed if your vehicle qualifies.
