Frequently Asked Questions
Which F-150 engine should I buy used?▼
The 5.0 V8 and 2.7 EcoBoost have the cleanest records this generation. The 3.5 EcoBoost is excellent when healthy but demands a cold-start listen for cam phaser rattle — or paperwork showing the phaser repair was already done.
Is the 10-speed transmission a problem?▼
Mostly a calibration story: harsh or clunky shifts usually respond to the accumulated software updates plus a fluid service. A truck that bangs into gear and was never updated is a cheap fix; persistent harshness after updates deserves a transmission-shop look.
