Understanding the 2019 Grand Cherokee oil capacity is essential for any owner or prospective buyer looking to maintain the peak performance of this luxury SUV. The 5.7-liter HEMI V8 engine, a cornerstone of the Grand Cherokee's capability, requires the correct volume of oil to ensure proper lubrication, cooling, and longevity. While the specifics might seem trivial, using the wrong amount or type can lead to increased friction, reduced fuel economy, and potentially severe engine damage over time.
Factory Specifications and Standard Fill
For the 2019 model year, Jeep equipped the Grand Cherokee primarily with the 3.6-liter Pentastar V6 and the 5.7-liter HEMI V8. When addressing the oil capacity for the 5.7 HEMI, the factory drain plug typically holds approximately 6.4 quarts of oil. However, this figure represents the oil remaining in the drain pan, not the total system capacity. To achieve a full system refill during an oil change, you generally need to add between 6.9 and 7.0 quarts of fresh oil to reach the correct operating level.
Variations Between Trims and Engines
It is crucial to note that oil capacity is not uniform across the entire 2019 Grand Cherokee lineup. While the 5.7-liter HEMI is the performance flagship, the base 3.6-liter Pentastar V6 utilizes a smaller oil pan and filter. Owners of the V6-powered models will find that the total oil capacity is lower, usually requiring around 5.5 to 6.0 quarts for a complete service. Always verify the specific engine configuration before purchasing supplies or filling the dipstick.
The Role of Oil Filter and Drain Plug
The difference between the oil sitting in the pan and the oil you pour into the fill port is the filter. The 2019 Grand Cherokee's oil filter has a significant capacity, holding roughly 0.5 to 0.7 quarts of oil depending on the brand and design. Consequently, when calculating how much oil to buy for an oil change, you must account for the filter's volume. A standard practice is to add 0.5 quarts more than the pan capacity to ensure the filter is primed and the system is full.
Engine Type | Oil Filter Capacity | Drain Plug Capacity | Total System Capacity
3.6L Pentastar V6 | 0.5 qt | 4.5 qt | ~5.0 qt
5.7L HEMI V8 | 0.7 qt | 6.4 qt | ~7.0 qt
Recommended Oil Specifications
Capacity is only one part of the equation; the quality and specification of the oil are equally important for the 2019 Grand Cherokee. Jeep engineers recommend using an SAE 5W-20 synthetic blend for optimal performance in most driving conditions. This viscosity provides the necessary protection during cold starts while maintaining stability at high engine temperatures. For those living in extreme climates or towing heavy loads, consulting the owner’s manual for specific weight recommendations is advised to ensure the HEMI runs smoothly.
