Does Ford Fusion require synthetic oil?

The Ford Fusion does not require synthetic oil exclusively. You can use conventional oil, synthetic blend, or full synthetic as long as it meets Ford’s specifications for your engine. The best choice depends on your model year, engine type, and climate. This article explains how to determine the right oil for your Fusion and how to manage changes and intervals.

What oil your Fusion can use

This section clarifies the oil options Ford generally accepts for Fusion engines and when you might choose each option.

• Conventional motor oil: Suitable for many older engines and normal driving in moderate climates. It’s the least expensive option and can be adequate for straightforward usage with proper maintenance.


• Synthetic-blend motor oil: A mix of conventional and synthetic that offers better protection and higher temperature stability than conventional oil, while typically keeping costs down. Good for most daily drivers and a wide range of engines.


• Full synthetic motor oil: Provides maximum protection, especially for turbocharged engines (EcoBoost variants), severe climates, or high-mileage engines. Often allows longer intervals between changes when driving conditions are favorable.

Note: Always verify the exact viscosity and certification required for your Fusion by checking the owner's manual or consulting a Ford dealership. The recommended viscosity for most Fusion engines is a light-viscosity option such as 5W-20, but some engines or climates may specify different grades.

Engine-specific considerations

Delve into how oil type can vary by engine and year, and what to check before choosing.

• 2.5L and older engines: In many model years, Ford allowed conventional, synthetic blend, or full synthetic oil with a 5W-20 viscosity; turbocharged EcoBoost engines tend to benefit from synthetic oil, particularly in hot or heavy-use conditions.


• EcoBoost engines (1.6L/2.0L): Often marketed to require higher-performance oil; synthetic or synthetic-blend oil is commonly recommended to protect turbochargers and high-temperature operation.


• High-mileage or extreme conditions: If the car has high mileage or is operated in extreme cold/heat, synthetic options can help reduce wear and maintain protection.

Regardless of engine, follow the manual’s specifications for viscosity and oil quality. If you are unsure, ask your dealer or a trusted mechanic for the exact Ford specification your VIN requires.

Oil change intervals and practical tips

Before changing oil, it's important to know typical intervals and practical tips to maximize engine life.

• Change intervals: Conventional oil often has shorter recommended intervals; synthetic oils typically extend intervals. However, many factors influence interval length, including driving style, climate, and oil-monitoring systems.


• Oil monitoring: Many Fusion models have an oil life monitor or maintenance reminder; follow its guidance in addition to general interval guidelines.


• Quality and certification: Use oil that meets Ford’s specification; avoid using oil that is not certified for Ford engines, even if it’s inexpensive or claims broad compatibility.

Bottom line: The right choice balances cost, engine protection, and maintenance schedule. If in doubt, lean toward a synthetic blend or full synthetic for modern Fusion engines and turbocharged variants.

Summary

Most Ford Fusion models do not require synthetic oil exclusively; conventional or synthetic-blend oils are acceptable as long as they meet Ford’s viscosity and certification requirements. Synthetic oils are generally recommended for turbocharged EcoBoost engines, extreme climates, and high-mileage applications, and they may permit longer intervals between changes. Always consult the owner's manual or a Ford dealer to confirm the correct oil type and viscosity for your exact model year and engine.

Note: Ford discontinued the Fusion in the U.S. after 2020, but maintenance principles for oil type and intervals still apply to remaining or imported models and to other Ford engines share similar guidance.

What year to stay away from Ford Fusion?

The Ford Fusion years to avoid are primarily 2010-2012 due to widespread power steering issues. The model years 2013-2016 should also be approached with caution due to potential head gasket problems with the EcoBoost engines and transmission issues, including recalls for certain transmissions.

Years to avoid

• 2010–2012: These model years are frequently cited as the worst for the Fusion, with power steering failure being the most common complaint. The 2010 model had the highest number of complaints, followed closely by 2011 and 2012. 
• 2013–2016: These years are associated with engine issues in EcoBoost models (1.5L, 1.6L, 2.0L), primarily head gasket failure, which can lead to expensive repairs. Some models from this range also had transmission problems and were subject to recalls. 

Specific problems

• Power Steering: A major issue in the 2010-2012 models, often resulting in a complete failure. 
• Engine: Head gasket failure in 1.5L, 1.6L, and 2.0L EcoBoost engines from 2013-2016 can cause coolant leaks and overheating. 
• Transmission: Some 2013-2016 models experienced shifting problems and leaks, leading to recalls and potential replacement. 
• Rust: In snowy climates, earlier models may have a higher susceptibility to rust. 
• Hybrid Batteries: The early hybrid versions had less robust batteries compared to some competitors. 

Does Ford Fusion need synthetic oil?

Your vehicle can take conventional (regular) oil or full synthetic oil. Our service team highly recommends full synthetic oil because it better suits your Ford engine and it will last longer.

What happens if you put synthetic oil in a non-synthetic car?

Putting synthetic oil where regular oil was used will not damage the engine, as the two are compatible. However, you won't get the full benefits of synthetic oil, and you may need to change the oil more frequently depending on the engine's condition. For older engines (over 75,000 miles), conventional oil is often recommended as it flows more slowly, which can better lubricate aging parts and prevent leaks. 
Engine compatibility

• No damage: There is no harm in switching back and forth between synthetic and conventional oil because they are compatible and can be mixed.
• No need for an engine flush: You do not need to flush your engine before switching, as the new oil will mix directly with the old oil of the same weight. 

Performance and benefits

• Reduced benefits: If you put synthetic oil in an older engine that was previously using conventional oil, you may not get the full benefits of synthetic oil, such as better performance at high temperatures and longer drain intervals. 
• Potential for leaks: In older engines, the smoother flow of synthetic oil might cause leaks, as it can get past worn seals that conventional oil couldn't. 
• Increased frequency: If you switch back to conventional oil after using synthetic, you may need to change your oil more frequently. 

Engine condition and recommendations

• Older engines: If your engine has over 75,000 miles, it may be best to stick with conventional oil for better lubrication. 
• Newer engines: Newer engines are generally better equipped to handle synthetic oil, and it is a good option for a cleaner, more efficient engine. 

Conclusion

• Switching is safe for most engines, but older engines may benefit more from staying with conventional oil. 
• Consider your vehicle's age and condition when deciding which oil to use. Consult your owner's manual for the manufacturer's specific recommendations. 

Which Ford vehicles require full synthetic oil?

All in all, it's vastly superior to conventional oil in every way, and typically enjoys more than double the lifespan, saving you on the cost of oil changes each year. Almost all modern Ford vehicles should use synthetic motor oil because it protects the engine better from harm.
