Understanding the 2018 Jeep Cherokee oil capacity is essential for maintaining the longevity and performance of your vehicle. This specific model year, part of the Cherokee's redesign era, requires precise attention to fluid specifications to ensure optimal engine operation. The correct volume of oil not only lubricates critical moving parts but also aids in cooling and cleaning the internal components, making this a fundamental aspect of routine maintenance.
2018 Jeep Cherokee Engine Specifications
The 2018 model year offered consumers a choice of two distinct powertrains, each with its own engineering requirements. These engines dictated the specific oil capacity and type needed to function correctly. Knowing which powerplant resides under your hood is the first step in determining the exact fluid volume for your maintenance procedure.
Available Engine Options
2.4L Tigershark MultiAir2 Inline Four-Cylinder
3.2L Pentastar V6
These two engines represented the performance spectrum for the Cherokee, with the four-cylinder designed for efficiency and the V6 focused on delivering robust power. Because the oil pan and internal geometry differ significantly between these configurations, the fluid capacity is not a one-size-fits-all specification.
Oil Capacity for the 2.4L Engine
For owners of the base model equipped with the 2.4L Tigershark engine, the oil capacity falls within a specific range that is critical to track. Filling beyond this limit can lead to increased pressure and potential seal issues, while underfilling can result in inadequate lubrication. Always consult your dipstick during the refill process to ensure accuracy.
2.4L Specifications
The factory fill for the 2.4L engine is generally 5.1 quarts of oil. When performing a DIY change, it is recommended to add approximately 4.5 quarts initially, then top off slowly while monitoring the dipstick to avoid overfilling. The use of a high-quality synthetic oil is generally recommended for this modern engine to ensure proper viscosity retention.
Oil Capacity for the 3.2L Engine
The 3.2L Pentastar V6 is a larger displacement powerplant that demands a greater volume of oil to ensure all bearings and valvetrain components are adequately protected. This engine is known for its smoothness and reliability, but it requires a precise amount of fluid to maintain its high standards of performance.
3.2L Specifications
The oil capacity for the 3.2L V6 is significantly higher at 6.8 quarts. Due to the increased capacity, it is often more cost-effective to perform the oil change with a new filter and fresh oil rather than attempting to top off an older charge. This ensures the integrity of the lubricant and extends the life of the engine.
