The 2023 Ford Bronco requires a 5W-30 full-synthetic motor oil. The exact capacity varies by engine: about 5.7 quarts for the 2.3L EcoBoost I-4 and about 6.0 quarts for the 2.7L EcoBoost V6, with the oil filter included in those figures. Always verify the latest specifications in the owner’s manual or on the under-hood label for your specific model.
Oil type and specifications
Engine options and oil implications
Whether you have the 2.3L EcoBoost or the 2.7L EcoBoost, Ford prescribes a high-quality synthetic oil of the same viscosity for normal operation. The key is to use a full-synthetic 5W-30 oil that meets Ford’s official specification for EcoBoost engines, as listed in the owner’s manual or service label. Always confirm the exact specification if Ford updates it for newer model years.
Key oil-grade and specification to verify before purchase
- Viscosity: 5W-30
- Type: Full synthetic motor oil
- Ford specification: WSS-M2C946-A or newer (or the equivalent specification listed by Ford for your vehicle)
- Engine compatibility: Suitable for both 2.3L EcoBoost and 2.7L EcoBoost engines
Using oil that does not meet Ford’s specification can affect engine performance and warranties, so follow the official spec in the manual or on the service label.
Oil capacity by engine
Below are the typical oil capacities for the Bronco, including the filter, by engine type. These figures are subject to change based on exact model configuration and any factory-installed hardware.
- 2.3L EcoBoost I-4: approximately 5.7 quarts
- 2.7L EcoBoost V6: approximately 6.0 quarts
After an oil change, fill to the full mark on the dipstick with the engine warm, then recheck to ensure accurate level alignment.
Maintenance and service reminders
Regular maintenance helps protect the Bronco’s engines and maintains warranty coverage. Here are the general guidance points to keep in mind.
- Follow the oil-life monitor in the instrument cluster to determine replacement timing.
- Under normal driving conditions, a typical interval is around 7,500 miles, but this can be shorter under severe conditions (hot climates, heavy dust, frequent short trips, or towing).
- Always use an approved drain and filter service with fresh oil, and reset the monitor after service if needed.
Summary
The 2023 Ford Bronco uses 5W-30 full-synthetic motor oil for both the 2.3L EcoBoost and the 2.7L EcoBoost engines. Oil capacity is about 5.7 quarts for the 2.3L and about 6.0 quarts for the 2.7L. Ensure the oil meets Ford’s specified standard (the exact code may be updated in the owner’s manual) and follow the recommended change intervals and service labels for best results.
