Which F-150 engine to avoid?

When it comes to the Ford F-150, the engine choice is crucial. While the F-150 offers a range of powerful and efficient engine options, there is one engine that is generally recommended to avoid: the 3.5L EcoBoost V6.


The 3.5L EcoBoost V6 Engine


The 3.5L EcoBoost V6 engine was introduced in the F-150 lineup as a more fuel-efficient alternative to the traditional V8 engines. It promised to deliver impressive power and towing capacity while improving fuel economy. However, this engine has been plagued with a number of issues that have made it a less desirable choice for many F-150 owners.


Common Issues with the 3.5L EcoBoost V6



  • Turbocharger Failure: The turbochargers in the 3.5L EcoBoost V6 are known to fail prematurely, leading to a loss of power and increased fuel consumption. This can be a costly repair, often requiring the replacement of the entire turbocharger assembly.

  • Oil Consumption: Many owners have reported excessive oil consumption with the 3.5L EcoBoost V6, requiring frequent top-ups to maintain proper oil levels. This can be a sign of more serious engine issues.

  • Reliability Concerns: The 3.5L EcoBoost V6 has a reputation for being less reliable than other F-150 engine options, with some owners experiencing a range of issues, including misfiring, rough idling, and even complete engine failure.


These issues have led many experts and F-150 owners to recommend avoiding the 3.5L EcoBoost V6 engine in favor of other, more reliable options, such as the 5.0L V8 or the 2.7L EcoBoost V6.


Alternative Engine Options


If you're in the market for an F-150, it's generally recommended to steer clear of the 3.5L EcoBoost V6 and instead consider the following engine options:



  • 5.0L V8: The 5.0L V8 engine is a tried-and-true option that offers excellent power and reliability. It's a popular choice among F-150 owners who prioritize performance and durability.

  • 2.7L EcoBoost V6: The 2.7L EcoBoost V6 is a more reliable and efficient turbocharged option that delivers impressive power and towing capacity without the issues associated with the 3.5L EcoBoost V6.

  • 3.3L V6: The naturally aspirated 3.3L V6 engine is a solid choice for those who prioritize fuel efficiency and reliability over raw power.


Ultimately, the choice of which F-150 engine to go with will depend on your specific needs and priorities. However, it's generally recommended to avoid the 3.5L EcoBoost V6 due to its reliability concerns and potential for costly repairs.
