Keeping your 2022 Jeep Cherokee 3.2L engine healthy requires fluids that can handle extreme temperatures, stop-and-go traffic, and the unique demands of its direct-injection system. Using the wrong lubricant can lead to premature wear, sludge buildup, and reduced fuel economy. Fortunately, there are several AMSOIL synthetic options designed specifically to exceed the requirements of this vehicle, offering superior protection whether you drive on highways or tackle rough terrain.

Selecting the right lubricant is critical because the 3.2L Pentastar engine is designed with tight tolerances and a complex cooling system. The engine oil must not only lubricate but also dissipate heat efficiently to prevent overheating, which can occur during steep climbs or when towing. Furthermore, the direct injection system makes the engine prone to carbon buildup, making the cleaning properties of these synthetic oils especially valuable.
Transmission and Cooling System Essentials
The 2022 Cherokee’s 9-speed automatic transmission is a marvel of engineering, but it requires a fluid that can handle high pressures and varying temperatures. Standard fluids can break down under stress, leading to sluggish shifts or premature wear. The AMSOIL Signature Series Fuel-Efficient ATF offers a distinct advantage here, remaining fluid even in sub-zero temperatures while protecting against the heat generated during heavy towing or off-road driving. For a total fill of the 948TE transmission, you will need approximately 6.3 quarts.
Cooling is equally vital. With a capacity of 10 quarts, the cooling system plays a massive role in the vehicle’s longevity. The AMSOIL Passenger Car & Light Truck Antifreeze is a pre-mixed 50/50 solution that eliminates the guesswork of mixing. Its unique OAT formulation ensures that metals, gaskets, and hoses are protected from corrosion without the harmful additives found in conventional coolants. For those who prefer to mix their own, the Propylene Glycol concentration offers a robust alternative with a longer service interval potential for heavy-duty use.
Maintaining Brakes and Engine Longevity
Brake fluid is often overlooked until it becomes wet or contaminated. The AMSOIL DOT 3 and DOT 4 Synthetic Brake Fluid is engineered to resist moisture absorption, which is a common cause of brake fade and corrosion in the ABS system. By maintaining a stable viscosity across a wide temperature range, it ensures consistent pedal feel and reliable stopping power, a crucial factor for a vehicle of this size.
For engine health beyond the oil change, fuel additives play a significant role. The AMSOIL P.i. Performance Improver is highly recommended for GDI engines like the 3.2L. Over time, these engines can develop carbon deposits on the intake valves, reducing horsepower and fuel efficiency. This additive helps restore injectors to 100% flow rate and can improve fuel economy by reducing the need for higher-octane fuel. It also helps control pre-ignition knock, a known issue in some direct-injection engines, ensuring the engine runs as smoothly as the day it was built.
About the Vehicle
The 2022 Jeep Cherokee remains a staple in the compact crossover segment, known for its blend of rugged capability and daily drivability. Based on the compact platform, it offers a spacious interior that belies its footprint, making it a favorite for families and outdoor enthusiasts alike. The 3.2-liter Pentastar V-6 engine, producing around 271 horsepower and 239 lb-ft of torque, provides a power delivery that feels substantial for highway merging and overtaking. This engine family is widely recognized for its smooth operation and durability, though it is not without its quirks, especially as vehicles accumulate mileage.
The Cherokee’s reputation is largely tied to its Freedom Drive I and II packages, which enhance its off-road prowess. The four-wheel-drive system, combined with available traction controls, allows it to handle light trails and snowy conditions with confidence. Unlike full-size trucks, the Cherokee strikes a balance, offering a comfortable ride on pavement while retaining enough ground clearance for unpaved paths. Its market position as an “urban adventure” vehicle appeals to drivers who want the Jeep brand’s heritage without sacrificing fuel economy or cargo space found in larger SUVs.
Owners of the 2022 Jeep Cherokee with the 3.2L engine often praise the V-6 for its smoothness and lack of turbo lag, which can be a concern in smaller turbocharged alternatives. However, like many modern direct-injection engines, this powerplant can be susceptible to specific issues over time. High-mileage owners frequently report oil consumption as a growing concern, where the engine uses more oil than normal due to wear in the piston rings or valve seals. This is a scenario where high-mileage synthetic oils, with their enhanced seal conditioners and anti-wear additives, can make a noticeable difference in maintaining compression and reducing oil top-offs.
Another common complaint involves carbon buildup on the intake valves, a direct consequence of the direct injection system. Because fuel is sprayed directly into the combustion chamber rather than over the valves, the intake ports can accumulate carbon deposits, leading to rough idling and reduced performance. While this is an inherent design characteristic, using high-quality synthetic fuels and additives designed to clean these systems can help mitigate the severity of the issue and maintain engine efficiency.
Finally, some owners have noted issues with the timing chain tensioners in higher-mileage examples, which can lead to rattling noises during cold starts. The increased viscosity stability of premium synthetic oils can help dampen these noises and provide a protective layer that reduces the wear on the tensioner components. Additionally, the 9-speed automatic transmission, while offering excellent gear ratios, can sometimes exhibit shuddering or harsh shifts, particularly in older units. Regular fluid changes with a high-quality synthetic fluid can help smooth out these shifts and extend the life of the transmission clutches. By addressing these common pain points with the right lubricants, owners can ensure their Cherokee remains a reliable companion for years to come.
Additional Care and Maintenance
Beyond the critical fluids, proper maintenance of the Cherokee involves attention to detail. For those storing their vehicle seasonally, the AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, preventing the varnish and gum buildup that can clog fuel injectors. If the vehicle is to sit for an extended period, an Engine Fogging Oil can protect internal components from rust and corrosion.
For general upkeep, the AMSOIL Synthetic Multi-Purpose Grease is ideal for chassis fittings, offering resistance to thermal degradation and water washout. When it comes to cleaning, the Power Foam® Cleaner can restore horsepower by removing carbon from the carburetor or induction systems, while the Miracle Wash waterless wash allows for spot-free cleaning that protects the paint against UV rays and salt. These products, along with the dedicated care for the engine and transmission, form a comprehensive maintenance strategy that keeps the 2022 Jeep Cherokee performing at its peak.
