Understanding the 2020 Jeep Grand Cherokee oil capacity is essential for proper vehicle maintenance and longevity. This specific model year, part of the renowned Jeep lineup, requires the correct amount of engine oil to ensure optimal performance and to protect the sophisticated powertrain components. Filling the reservoir to the precise level prevents both the dangers of under-lubrication and the performance issues caused by overfilling.
2020 Grand Cherokee Engine Specifications and Oil Requirements
The 2020 model year offered a range of powerful engines, and the oil capacity varies significantly depending on which powertrain you own. The base models typically feature the 3.6-liter Pentastar V6, while higher trims boast the robust 5.7-liter HEMI V8 or the turbocharged 3.0-liter EcoDiesel I6. Each of these engines has a different design and displacement, which directly dictates the total volume of oil needed for the sump and filter system.
Capacity for the 3.6L Pentastar V6
For the standard 3.6-liter Pentastar V6 engine, the total oil system capacity is generally around 6.4 quarts (6.1 liters). This figure includes the oil that fills the engine block and the filter. When performing an oil change, it is recommended to add approximately 5 to 5.5 quarts of fresh oil initially, then top off slowly while monitoring the dipstick to reach the exact level. Always refer to the specific recommendations listed in your owner’s manual, as variations can occur based on the manufacturing date and options package.
Capacity for the 5.7L HEMI V8 and EcoDiesel I6
Vehicles equipped with the larger 5.7-liter HEMI V8 engine require a greater volume of oil due to the increased number of cylinders and larger oil pan. The total oil capacity for this V8 is typically around 6.8 quarts (6.4 liters). Similarly, the 3.0-liter EcoDiesel engine, known for its durability and torque, also has a larger oil system. Owners of the EcoDiesel model should expect a total capacity of roughly 7.9 quarts (7.5 liters), making it the highest capacity engine in the 2020 lineup.
The Importance of Using the Correct Oil Type
Knowing the capacity is only half the battle; selecting the proper oil viscosity and specification is equally critical for the 2020 Grand Cherokee. Jeep engineers recommend using a high-quality synthetic oil that meets the API SP standard. For most climates, a 5W-20 viscosity is ideal for the Pentastar and EcoDiesel engines, as it provides excellent cold-start protection and fuel efficiency. The HEMI V8 can also utilize 5W-20, though some owners in extreme heat may opt for a 5W-30 to maintain optimal film strength at higher temperatures.
Step-by-Step Oil Change Procedure
To accurately determine the oil capacity for your specific vehicle, you can perform a controlled oil change while measuring the fluid. Begin by warming up the engine for a few minutes to allow the old oil to flow freely, then safely lift the vehicle and secure it with jack stands. Locate the drain plug and remove the oil filter, allowing the old oil to drain completely into a catch pan. Once drained, install the new filter and add the new oil gradually. For the 5.7L HEMI, stop at around 6.5 quarts and check the level; for the 3.6L, add roughly 5 quarts before checking.
