The 2018 Ford Explorer is one of the most popular midsize SUVs thanks to its strong engine options, towing capability, and comfortable daily driving performance. Whether your Explorer is equipped with the reliable 3.5L V6, fuel-efficient 2.3L EcoBoost, or powerful 3.5L EcoBoost, using the correct engine oil is essential for protecting the engine and maximizing long-term reliability.
Choosing the proper oil viscosity helps reduce internal engine wear, improve fuel economy, maintain turbocharger protection on EcoBoost models, and prevent sludge buildup. Regular oil changes also help extend engine life and maintain smoother engine performance in both hot and cold weather conditions.
2018 Ford Explorer Oil Type
The recommended oil type for the 2018 Ford Explorer depends on the engine option installed in the vehicle. Most models commonly use SAE 5W-30 full synthetic engine oil, which offers excellent lubrication, engine cleanliness, and temperature protection.
Ford recommends using oils that meet Ford specification WSS-M2C946-A or newer standards. Full synthetic oil is strongly recommended for EcoBoost engines because turbocharged engines operate at higher temperatures and require superior oil stability.
Best Overall Choice: Full synthetic SAE 5W-30 engine oil provides the best combination of wear protection, fuel efficiency, turbocharger protection, and long-term engine cleanliness for the 2018 Ford Explorer.
2018 Ford Explorer Oil Capacity
Oil capacity varies depending on the engine installed in your Ford Explorer. Always verify the oil level using the dipstick after refilling because capacities may vary slightly based on oil filter replacement and engine configuration.
Important: EcoBoost engines should always use high-quality synthetic oil because turbocharged engines generate higher operating temperatures than naturally aspirated engines.
