What Is The 2.7L EcoBoost Engine?

2.7L ecoboost engine longevity

The 2.7L EcoBoost is a gasoline V6 engine, first introduced in 2015 on the Ford F-150. Since its debut appearance, it has grown in popularity among several Ford and Lincoln Cars. The turbocharged engine produces an average of 315-335 horsepower and 350-400 ft-lb of torque. The 2.7L also features a higher fuel efficiency compared to other engines out there.

The engine comes in two generations, the first-gen stretching from 2015-2017, with the second being in production from 2018 to date. The second-gen 2.7L featured multiple upgrades that were aimed towards reducing friction and increasing reliability. The notable upgrades include;

  • Lightweight cams
  • High-pressure EGR system
  • Electronically-controlled turbo waste-gates

Both generations of the 2.7L EcoBoost are reliable engines. It’s incredible how they foster fuel economy without sacrificing output.

What Cars Have The 2.7L EcoBoost Engine?

The first-gen variant of the 2.7L EcoBoost is available in the following car models:

  • 2016 – 2018 Lincoln MKX
  • 2015 – 2017 Ford F-150
  • 20217 – 2020 Lincoln Continental
  • 2015 – 2018 Ford Edge Sport
  • 2017 – 2019 Ford Fusion Sport
  • 2019 – present Ford Edge ST
  • 2019 – present Lincoln Nautilus

The second-generation 2.7L EcoBoost is found in these models:

  • 2018 – present Ford F-150
  • 2021 Ford Bronco

The first-generation 2.7L engines were not that good when compared to the second-gen. Most users of the first-gen engines reported experiencing three significant problems with the engines including;

  • Oil pan leaks
  • Carbon build-up
  • Spark plugs and ignition coils

However, Ford rectified these shortcomings in the second-generation 2.7L EcoBoost engines to increase reliability. They replaced the direct injection in the first-gen engine with the port injection design to curb carbon build-up. Likewise, pan leaks were taken care of, and spark plugs were improved in design to help prevent prior-related spark-plug problems. 

What Is The 2.7L EcoBoost Engine Longevity?

The 2.7L EcoBoost longevity is around 200,000 miles. However, the engine can last longer if maintained properly. Users report achieving high numbers with the engine only after quality and timely maintenance. 

How To Increase The 2.7L EcoBoost Engine Lifespan

As previously stated, the 2.7L EcoBoost can rack up to 200,000 miles before experiencing significant problems. So what will make your engine surpass the 200,000-mile mark?

Here are some tips to increase your engine’s lifespan. 

how to extend 2.7L ecoboost engine lifespan

Perform Regular Oil Changes

The worst enemy to an engine is friction. It eats up the tiny expensive-to-replace internal parts of the engine. Therefore, you must regularly check your oil levels before starting your engine. Top up the oil if necessary. 

Again, don’t forget to watch out for oil leaks.

Check Your Filters Regularly

Make sure to inspect your air and oil filters regularly for dirt or malfunction.

Blocked air filters prevent the entry of oxygen into the engine’s combustion chamber. As a result, the engine is forced to cater to the lack of oxygen by burning more fuel, which leads to decreased efficiency in the long run. 

Oil filters should also be dirt-free. Deposits in the oil filters prevent the free flow of oil, which can be dangerous to your engine. If the filter is blocked completely, then you’re running into a big problem. 

Moreover, broken filters could be more dangerous. They let dirt find its way into the engine block and may cause harm to the engine valves. You should have your filters checked and replaced if necessary. 

Use The Recommended Fuel For Your Engine

Don’t force your engine to work with non-recommended fuels. Always be keen while at the filling station to ensure your tank is filled up with the right fuel.

Check On Your Cooling System

Overheating significantly reduces your engine’s life expectancy. To curb the problem, make sure to always check on the state of your coolant. Keep the radiator fluid at a low temperature. Replace it regularly. Again, if you have to go on a long journey, always let the engine cool down. 

Don’t Ignore Dash Signs

Your car has a way of checking the engine for possible problems. Occasionally, it will warn you that there might be a problem with either your engine, coolant system, or any other related issue. So be sure to check it out before it’s too late. 

Besides, it would be best if you didn’t wait for the dash sign to pop up. Instead, get your engine checked regularly for any underlying complications. 

Change Spark Plugs and Wires Frequently

Wires and spark plugs can become dangerous to your engine when they get too old. Therefore, it is recommended that they are changed every 30,000 miles. Now that the first-gen 2.7L EcoBoost engine experienced problems with its spark plugs, that can be a handy remedy. But, again, changing spark plugs and wires is not a costly investment in both money and time. After the replacement, you’ll notice that the engine fires consistently and also has high fuel efficiency. 


The 2.7L EcoBoost engine has been available for over five years. The newer and upgraded version released in 2018 covers up for the mistakes in the first gen, which seemed pretty competitive and reliable. Regardless of all that, you still get a minimum of 200,000 miles on the 2.7L EcoBoost, which can be more under proper maintenance. However, it could be less than that if you’re careless. 

Like all other engines, you should expect to experience problems here and there as the engine ages and accrues mileage.
