Most gasoline engines in the Ford F-150 require SAE 5W-30 or SAE 5W-20 engine oil meeting Ford engineering specification WSS-M2C961-A1 or updated specification WSS-M2C971-A1. Ford recommends using Motorcraft synthetic blend or full synthetic motor oil formulated to protect high-output EcoBoost turbochargers, prevent low-speed pre-ignition, and maintain full 5-year/60,000-mile powertrain warranty coverage.
