Maintaining the 2018 Ford Fusion requires attention to the most fundamental aspect of engine care: the oil change. This specific model, a mid-size sedan known for its refined performance and efficiency, relies on consistent lubrication to keep its turbocharged or standard engine running smoothly. Using the correct oil, whether conventional or synthetic, is vital for reducing friction and managing the heat generated by the sophisticated powertrain.
Understanding the 2018 Ford Fusion Engine Specifications
The 2018 model year offered a range of powertrains that dictated the oil change procedure. Owners could choose between a 2.5L 4-cylinder, a 1.5L EcoBoost, or a 2.0L EcoBoost engine. Each variant has specific requirements regarding oil viscosity and capacity. Generally, the recommended oil is 5W-20, which provides the necessary protection while optimizing fuel economy, a key selling point for this Fusion generation.
Step-by-Step Oil Change Procedure
Performing a DIY oil change on a 2018 Fusion involves several critical steps to ensure the job is done correctly. First, the vehicle must be lifted safely using jack stands if the undercarriage needs to be accessed, as the drain plug is located underneath the engine. It is essential to warm up the engine slightly before draining the oil, as this allows the old oil to flow more freely and carry out contaminants effectively.
Draining the Old Oil
Locating the oil drain plug and placing a catch basin underneath is the first physical step. Removing the plug allows the oil to drain completely, which usually takes a few minutes. While the oil is draining, the old gasket on the drain plug should be replaced with a new one to prevent future leaks. Additionally, the oil filter, typically located near the front of the engine, must be removed and replaced with a new one filled with fresh oil to ensure proper lubrication upon restart.
Torque Specifications and Oil Capacity
When reinstalling the drain plug, it is critical not to overtighten it, as this can strip the threads or damage the oil pan. The specified torque is usually around 15-20 ft-lbs, but checking the owner’s manual is always the best practice. The 2018 Fusion generally holds between 3.5 to 4.0 quarts of oil. Failing to add the correct amount can lead to low oil pressure or overfilling, which causes excessive pressure and potential damage to the seals.
Choosing the Right Oil and Filter
Selecting the appropriate oil filter is just as important as choosing the right oil. A high-quality filter ensures that debris and metal shavings are trapped, protecting the moving parts inside the engine. For the 2018 Fusion, looking for a filter that meets Ford’s WSS-M2C947-A or similar specification is recommended. Synthetic oil is often preferred for its superior performance in temperature extremes and longer change intervals, though conventional oil remains a cost-effective option for standard driving conditions.
Resetting the Maintenance Light
After the physical process is complete, the vehicle’s maintenance reminder system must be reset. This step is often overlooked but is crucial for keeping the car's electronic systems accurate. The process typically involves turning the ignition to the "On" position without starting the engine and pressing the accelerator pedal in a specific sequence. Refer to the owner’s manual for the exact procedure for the 2018 model, as it varies slightly between trims and years.
