The 2018 Explorer 3.5 oil capacity is a specific figure that matters for maintaining the longevity and performance of your vehicle. Understanding the exact amount of lubricant required for the 3.5-liter V6 engine ensures proper lubrication, cooling, and cleaning cycles within the system. This detailed specification is crucial for both routine maintenance and for owners who perform their own oil changes, as using the correct volume is just as important as selecting the right oil grade.
2018 Ford Explorer 3.5L Engine Specifications
The 2018 Ford Explorer utilizes a robust 3.5-liter EcoBoost V6 engine, which delivers a balance of power and efficiency for daily driving and towing. This specific powertrain configuration requires a precise volume of oil to function optimally under various temperature conditions. The engine's design incorporates advanced features that necessitate a specific fill amount to ensure all components are adequately protected during operation.
Exact Oil Capacity and Fill Procedure
For the 2018 Explorer with the 3.5L engine, the total oil capacity is generally around 6.2 quarts. However, this figure includes the oil filter, so the amount poured directly into the engine is usually closer to 5 quarts before installing the new filter. Mechanics recommend checking the dipstick multiple times during the refill process to avoid overfilling, which can lead to increased pressure and potential seal damage.
Ensure the vehicle is parked on a level surface.
Locate the oil drain plug and allow the old oil to drain completely.
Replace the drain plug and install a new, compatible oil filter.
Pour approximately 5 quarts of the recommended oil into the fill port.
Start the engine and let it run for several minutes, then turn it off.
Wait a few minutes and check the dipstick to determine the exact level.
Recommended Oil Type and Viscosity
To achieve the stated 2018 Explorer 3.5 oil capacity effectively, using the correct oil viscosity is essential. Ford typically recommends 5W-20 synthetic blend or full synthetic oil for this engine. This viscosity provides the necessary protection during cold starts and maintains stability under high-temperature conditions, ensuring the oil performs its lubricative duties without becoming too thin or too thick.
Consequences of Incorrect Oil Levels
Adding too little oil can result in insufficient lubrication, leading to increased friction, overheating, and premature engine wear. Conversely, overfilling the crankcase can cause oil to become aerated, reducing its lubricating effectiveness and potentially leading to oil leaks or damage to the crankshaft seals. Adhering to the specified capacity prevents these common and costly mistakes.
Maintenance Schedule and Tips
Regular oil changes are vital for the health of the 2018 Explorer's engine. Following the manufacturer's recommended intervals, usually every 7,500 to 10,000 miles for synthetic oil, helps maintain optimal performance. When performing maintenance, always reset the oil life tracker in the vehicle's system to ensure accurate future reminders.
