Owners of a 2019 Ford Explorer need to understand the specific oil requirements for their vehicle to ensure optimal performance and longevity. Using the correct viscosity and specification is not just a matter of maintenance; it is a critical factor in the efficiency of the engine, fuel economy, and overall reliability of the SUV. This guide breaks down everything you need to know about the 2019 Ford Explorer oil type, helping you make the right choice for your specific model year and engine configuration.
Understanding the 2019 Engine Options
The 2019 model year offered a distinct difference in oil requirements depending on which engine you purchased. Ford utilized two primary powertrains that year, and confusing them can lead to improper maintenance. While the base model featured a turbocharged four-cylinder, the more powerful variants were equipped with a V6, and later in the year, a hybrid option joined the lineup. Identifying your specific engine is the first step in determining the correct oil.
The 2.3L EcoBoost Engine
For customers who opted for the standard 2.3L four-cylinder EcoBoost engine, the oil requirements were specific to balance the needs of forced induction. This engine required a high-quality synthetic oil to handle the heat and stress generated by the turbocharger. The recommended viscosity was 5W-20, which provides a balance of protection and fuel efficiency. Always look for oil that meets the Ford WSS-M2C947-A standard to ensure it contains the correct additives for the turbocharged components.
The 3.0L V6 Engine
Drivers who chose the more robust 3.0L V6 engine found that this powertrain demanded a slightly different approach. While still requiring synthetic oil, the V6 performed best with a 5W-20 viscosity rating in most conditions. However, Ford also specified that this engine met the dexos1™ Gen 2 standard, which is commonly found in many modern GM vehicles but was also approved for this Ford application. This specification ensures the oil has the necessary detergents and anti-wear properties to protect the larger and more complex V6 architecture.
Viscosity: Why 5W-20 is Standard
Across the majority of the 2019 Explorer lineup, whether equipped with the four-cylinder or the V6, the factory fill and recommended oil viscosity is 5W-20. The "5W" portion of the rating indicates the oil's cold-flow properties, meaning it remains fluid in freezing temperatures to ensure easy starts and immediate lubrication. The "20" refers to the oil's thickness at operating temperature, designed to be thin enough to improve fuel economy while still maintaining a sufficient film strength to protect moving parts under stress.
