Ensuring your vehicle receives the correct lubrication starts with the engine oil. The 2023 Ford Bronco’s 2.7L twin-turbo engine operates under significant thermal and mechanical stress. Selecting the right viscosity is key to maintaining oil pressure and protecting components. For this engine, a 5W-30 viscosity is specified for operation above -29°C. If you frequently drive in extreme cold where ambient temperatures drop to -22°F (-30°C) or below, a 0W-30 viscosity meeting the Ford specification WSS-M2C963-A1 may be required for improved cold starts. The engine oil capacity is 6.0 quarts when including the filter change. After refilling, it is vital to check the oil level to ensure the correct amount is present.
Among the recommended oils, AMSOIL Signature Series 5W-30 stands out as the ultimate choice for this application. It is backed by a 25,000-mile or 1-year guarantee and provides superior protection against horsepower loss and wear. For owners seeking extended service intervals without compromising protection, the Extended-Life 5W-30 offers up to 20,000 miles of protection. It also features enhanced cleaning power to maintain engine cleanliness. The OE 5W-30 is an excellent cost-effective alternative that still delivers 100% synthetic performance, fighting sludge and deposits effectively. Additionally, the High-Mileage 5W-30 is ideal for Bronco models that have surpassed 75,000 miles, offering a unique chemistry that reduces sludge and protects seals.
Matching your oil with the correct filtration is equally important. The 2023 Bronco requires a filter that can handle high volumes of contaminants and maintain low restriction to ensure proper lubrication. The AMSOIL Oil Filter provides 99% filtration efficiency at 20 microns and offers greater capacity for small contaminants than competing brands, significantly reducing engine wear. For those preferring the WIX Oil Filter, it is a compatible option that offers improvements over OEM-branded filters, ensuring reliable filtration performance.
Cooling system maintenance is crucial for the turbocharged engine of the Bronco. With a coolant capacity of 12.4 quarts, using a high-quality antifreeze is essential. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mixed formulation that exceeds original equipment requirements. It is designed to protect all cooling system metals, gaskets, and hoses for up to 150,000 miles or 5 years. For those who prefer to mix their own coolant, the concentrated AMSOIL Propylene Glycol Antifreeze is a phosphate-, nitrate-, and silicate-free option that offers protection for up to 150,000 miles and greatly surpasses standards for metallic corrosion and erosion.
Transmission fluid selection depends on the specific transmission type installed in your Bronco. The 10R60 automatic transmission requires a fluid capable of withstanding heavy towing, elevated temperatures, and challenging terrain. AMSOIL Signature Series ULV 100% Synthetic Automatic Transmission Fluid is formulated for this purpose, remaining fluid in sub-zero temperatures and providing reserve protection during heavy use. The total fill capacity is 13.1 quarts, while the initial fill requires 5.1 quarts. For manual transmissions or DCT systems, such as the MT88, AMSOIL 100% Synthetic DCT Fluid is recommended. It offers outstanding wear protection and is designed to prevent shudder, ensuring smooth operation in extreme heat and cold. The manual transmission capacity is 5.1 pints.
The drivetrain components, including the transfer case and differentials, also demand high-performance lubricants. The transfer case, particularly those with 4A mode, requires specific lubrication. For the front differential, the requirement is for SAE 80W-90 oil meeting Ford specification WSP-M2C197-A. Both the AMSOIL SEVERE GEAR® 80W-90 and 75W-90 synthetic gear lubes meet these specifications. The 80W-90 contains friction modifiers for limited-slip applications and helps control thermal runaway. The 75W-90 is another excellent choice that controls thermal runaway and reduces operating temperatures. The rear differential with electronic locking differentials (ELD) requires a 75W-85 synthetic oil. AMSOIL SEVERE GEAR® 75W-85 is the recommended synthetic lubricant for this application, providing advanced protection against wear and rust. The transfer case capacity varies depending on the mode, ranging from 2.5 to 3.2 pints, while the front differential capacities are approximately 1.7 to 1.9 pints and the rear is around 4 to 4.1 pints depending on the presence of the ELD.
AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid performance is critical for safety. The 2023 Ford Bronco recommends Motorcraft DOT 4 LV High Performance Brake Fluid. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is a suitable high-performance replacement. It provides excellent responsiveness for ABS and traction-control systems and maintains a stable viscosity over a wide temperature range, ensuring consistent braking power under various driving conditions.
For owners who plan to store their vehicles seasonally or wish to maintain peak fuel system performance, AMSOIL offers specialized additives. The AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months and protects against varnish and ethanol corrosion. The AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor lubricates the fuel system and upper cylinders, compatible with capless fuel systems. Additionally, the P.i.® AMSOIL Performance Improver Gasoline Additive is a powerful treatment that can restore up to 14% horsepower and clean GDI fuel injectors back to 100% flow rate after a single tank of fuel.
