Understanding the specific lubrication needs of your vehicle is the first step toward maximizing its lifespan. For the 3.3-liter 6-cylinder Flex Fuel engine, the manufacturer specifies a 5W-20 viscosity. While conventional oils meet the baseline requirements, synthetic alternatives like AMSOIL Signature Series Motor Oil offer a significant advantage by providing a stronger film strength that resists breakdown under heat and stress. This is particularly important for the Explorer, which is often used for towing or driving in heavy stop-and-go traffic where engine temperatures can rise rapidly. Using a synthetic motor oil allows for extended drain intervals, reducing the frequency of maintenance without compromising engine protection. The recommended capacity for an oil change, including the AMSOIL Oil Filter, is 6.0 quarts. It is crucial to refill to the specified level and verify the oil level on the dipstick after the refill to ensure proper lubrication of the internal engine components.
Beyond the crankcase, the cooling system plays a vital role in managing engine temperature. The 2023 Ford Explorer requires a significant amount of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant, with capacities varying based on the rear heater configuration. Vehicles equipped with a rear heater require approximately 12.9 to 15.2 quarts depending on the specific configuration. AMSOIL’s antifreeze formulations are engineered to exceed original equipment manufacturer requirements, utilizing a unique poly-organic acid technology that protects all cooling system metals, gaskets, and hoses. The ethylene glycol pre-mix is ready to use, while the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers a more eco-friendly option that can be mixed to achieve a 50/50 ratio. Both options provide protection against corrosion and freezing for up to 5 years or 150,000 miles, significantly outlasting conventional green antifreezes.
Transmission health is equally critical for a vehicle of this size and capability. While no specific transmission fluid recommendation appears in the primary lookup for this engine code, the Explorer’s automatic transmission benefits immensely from high-quality synthetic lubricants. AMSOIL’s fuel-efficient Signature Series Automatic Transmission Fluid is designed to remain fluid in sub-zero temperatures and withstand the rigors of heavy towing and elevated operating temperatures. These fluids provide reserve protection during heavy use, helping to prevent sludge formation and ensuring smooth shifting. Whether you choose the Signature Series for maximum performance or the AMSOIL OE Automatic Transmission Fluid for standard maintenance, using a dedicated synthetic transmission fluid helps preserve the transmission’s lifespan and efficiency.
The drivetrain of the Ford Explorer also requires specialized attention. The front differential and transfer case call for a 75W-140 viscosity AMSOIL SEVERE GEAR Gear Lube, with a capacity of 1.3 pints for the front and 2.1 pints for the transfer case. The rear differential, conversely, requires a 75W-85 synthetic AMSOIL SEVERE GEAR Gear Lube with a capacity of 3.4 pints. These specific viscosities are necessary to protect the hypoid gears and bearings within the axles, especially under load. AMSOIL’s SEVERE GEAR line contains friction modifiers suitable for limited-slip applications and is formulated to control thermal runaway, a condition where the fluid degrades rapidly under heavy stress. By using these dedicated gear lubes, you ensure that the differentials operate smoothly and efficiently, regardless of the terrain or load conditions.
Braking performance should never be overlooked in a vehicle as heavy as the Explorer. The recommended AMSOIL DOT 3 and DOT 4 Brake Fluid meets DOT 3 and DOT 4 standards, and AMSOIL’s synthetic brake fluid is an ideal upgrade. It provides a stable viscosity over a wide temperature range, ensuring consistent pedal feel and responsiveness even after repeated hard stops. This stability is crucial for the anti-lock braking system (ABS) and traction control, enhancing safety during emergency maneuvers. Regularly flushing the brake system with a high-quality synthetic fluid helps prevent moisture absorption, which can lead to corrosion and reduced boiling points, ensuring the braking system remains reliable for years.
