Is the Ranger's 2.3L EcoBoost as reliable as the same engine in the Explorer and Bronco?
The 2.3L EcoBoost (G2LC) shared across the Ranger, Explorer and Bronco Sport is one of the most thoroughly developed Ford engines of the past decade. The timing chain concerns reported on early 2.0L and 3.5L EcoBoost generations are absent here. The main maintenance disciplines are straightforward: 0W-30 or 5W-30 full synthetic oil changes every 8,000 km, injector deposits on intake valves addressed with a walnut-blast cleaning at approximately 120,000 km, and a mandatory 10-speed transmission fluid drain at 100,000 km to protect the gearbox long-term.
