Maintaining the 2015 Ford Explorer is essential for ensuring its longevity and performance, and understanding the specifics of the oil change procedure is a fundamental aspect of this care. This large mid-size SUV, equipped with either a 3.5-liter EcoBoost V6 or a 3.3-liter V6 engine, relies on consistent lubrication to keep its complex powertrain running smoothly. Using the correct oil, whether it is conventional, synthetic blend, or full synthetic, directly impacts fuel efficiency, engine longevity, and the overall driving experience in this capable vehicle.
Understanding Your 2015 Explorer's Oil Requirements
Before beginning any maintenance, it is critical to identify the specific engine configuration in your 2015 Ford Explorer. The recommended oil specifications vary significantly between the standard V6 and the more powerful EcoBoost variants. For the base 3.3L V6, Ford typically specifies 5W-20 motor oil, a lighter viscosity that helps optimize fuel economy. In contrast, the 3.5L EcoBoost engine often requires 5W-30 oil to provide the necessary protection under higher stress and performance conditions. Always refer to the vehicle’s placard, usually located on the driver’s side door jamb, to confirm the exact oil weight and capacity for your specific model year and engine.
Selecting the Right Oil and Filter
Choosing the correct oil filter is just as important as selecting the right viscosity. A high-quality filter ensures that contaminants are trapped effectively, protecting the precision-machined components of the 2015 Explorer’s engine. When purchasing supplies, look for filters that meet Ford’s specifications, often denoted by the Motorcraft brand for OEM-equivalent quality. If you opt for a synthetic blend or full synthetic oil, ensure the product meets the API SN or SM service standards. Using an incorrect filter can lead to reduced filtration efficiency or even improper sealing, which can cause serious engine damage over time.
Step-by-Step Oil Change Procedure
Performing an oil change on the 2015 Explorer involves several key steps that require attention to detail. First, the vehicle must be warmed up to allow the old oil to flow more freely, though it should be cool enough to touch safely before draining. You will need to lift the front of the SUV using a jack and secure it with jack stands, as the oil drain plug is located underneath the engine. It is also advisable to place a large catch pan directly beneath the plug, as the oil can drain quickly and at a significant volume, often ranging from 5 to 6 quarts depending on the engine.
Locate the oil drain plug and remove it carefully, allowing the oil to drain completely.
Replace the drain washer if it is damaged or deformed, then reinstall the plug securely.
Remove the old oil filter using the appropriate filter wrench.
Before installing the new filter, apply a small amount of fresh oil to the gasket.
Fill the engine with the manufacturer-specified amount and type of new oil.
Torque Specifications and Capacities
Following the manufacturer’s torque specifications is non-negotiable when servicing the 2015 Ford Explorer. Over-tightening the oil drain plug or the oil filter can strip the threads or damage the sealing surfaces, leading to expensive leaks. Conversely, under-tightening can result in catastrophic oil loss while driving. Consulting a torque wrench is highly recommended for this task. The following table outlines the general capacities and torque figures for the common engine options found in the 2015 model year.
