Ford F-150 Engines Ranked: Best and Worst Engines to Buy

Engine generation is one of the most important details to check when comparing used Ford F-150s. Two trucks can have the same engine displacement while using substantially different versions of that engine. The 3.5L EcoBoost is a good example. The second-generation version arrived for 2017 with important revisions, including changes to the timing system and the addition of port injection alongside direct injection. For newer used trucks, the 2018+ 2.7L EcoBoost, second-generation 3.5L EcoBoost, and 5.0L Coyote V8 each suit a different type of buyer. The 2.7L offers a useful balance of performance and efficiency for everyday use and moderate towing. The 3.5L provides stronger low-rpm torque when towing and heavier work are priorities. The naturally aspirated 5.0L appeals to buyers who want V8 performance without a turbocharged induction system.

Older F-150s require more careful selection. The 2004–2010 5.4L Triton 3-valve deserves particular attention to cold-start noise, timing components, cam phasers, spark-plug service, and oil-change history. Early 3.5L EcoBoost trucks also warrant closer inspection for first-generation trouble areas. If you’re buying used, don’t choose an F-150 from the engine’s reputation alone. Confirm the exact engine and generation, review maintenance records, listen to a genuine cold start, check how the truck was previously used, and consider a pre-purchase inspection before buying a higher-mileage example.
