Ensuring the proper lubrication of your 2022 Jeep Grand Cherokee equipped with the 5.7L V8 engine is crucial for maintaining its performance and extending its service life. This powerful engine, part of the highly regarded HEMI family, demands fluids that can handle high operating temperatures, heavy towing loads, and the demands of off-road adventures without breaking down. Using the correct viscosity and high-quality additives ensures optimal engine protection, fuel economy, and shifting smoothness across all driving conditions.
Recommended AMSOIL Products
For the 2022 Jeep Grand Cherokee 5.7L, the manufacturer specifies a 0W-20 viscosity motor oil.

Essential Fluids for the 5.7L Powertrain
Beyond engine oil, the longevity of your Grand Cherokee depends on the condition of its transmission fluid, cooling system, and differential lubricants. The 2022 model utilizes the 8HP75 automatic transmission, which operates at high temperatures and requires a fluid that resists thermal breakdown. AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid is designed to withstand the rigors of heavy towing and elevated temperatures while remaining fluid in sub-zero conditions. For those seeking a budget-friendly alternative that still meets OE standards, the OE Fuel-Efficient Automatic Transmission Fluid is an excellent choice.
The cooling system is critical for the 5.7L HEMI engine, which can run quite hot during spirited driving or towing. The recommended coolant capacity is 15 quarts. You can protect your cooling system with AMSOIL Passenger Car & Light Truck Antifreeze & Coolant, a unique poly-organic acid (OAT) formulation that protects all cooling system metals, gaskets, and hoses for up to 150,000 miles. Alternatively, the Propylene Glycol Antifreeze & Engine Coolant offers a concentrated solution that greatly surpasses standards for metallic corrosion and erosion.
Gear Lubrication and Transfer Case Care
The Grand Cherokee’s all-wheel-drive system relies on a transfer case and front and rear differentials that require specific lubrication. For the front differential (195FIA) and rear differentials (195RIA, 230RIA), AMSOIL recommends SEVERE GEAR® 75W-85 100% Synthetic Gear Lube. This advanced fluid provides protection against wear, controls thermal runaway, and helps reduce operating temperatures. It also contains friction modifiers for limited-slip applications. Note that the rear differential with an Electronic Limited Slip Differential (ELSD) requires a specific Mopar lubricant with a modifier; however, for the 195FIA and 195RIA units, the SEVERE GEAR fluid is the optimal synthetic choice.
The transfer case varies by model (MPT3015C or MPT3028C) and requires either 1.7 or 3 pints respectively. In these applications, the AMSOIL Signature Series Multi-Vehicle Automatic Transmission Fluid can be used as a high-performance alternative to handle the demands of 4WD systems. Similarly, for the front differential, the Multi-Vehicle OE Multi-Vehicle Automatic Transmission Fluid is suitable. To ensure optimal braking performance, the AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides stable viscosity over a wide temperature range, ensuring excellent ABS and traction-control responsiveness.
Maintenance and Fluid Capacities
When performing your oil change, ensure you have the correct amount of fluid on hand. The 5.7L engine requires 7.0 quarts of motor oil, including the filter replacement. After refilling, always check the oil level to ensure it is within the proper range. The torque specification for the oil drain plug is 25 ft/lbs. For the cooling system, a total capacity of 15 quarts is required. The automatic transmission (8-speed 8HP75) has a total fill capacity of 9.5 quarts. Differential capacities vary by axle, but generally require small amounts of gear lube, with front axles needing 1.3 pints and rear axles requiring between 1.9 and 2.7 pints depending on the configuration.
Additional Protection and Maintenance Products
For seasonal storage, consider using AMSOIL Gasoline Stabilizer to keep fuel fresh for up to 12 months and prevent varnish buildup. If you plan to store the vehicle for extended periods, AMSOIL Engine Fogging Oil can protect internal components from rust. To maintain fuel system cleanliness and performance, AMSOIL P.i. Performance Improver Gasoline Additive can restore up to 14% horsepower and improve fuel economy. For general vehicle care, products like the AMSOIL Synthetic Multi-Purpose Grease are excellent for chassis lubrication, resisting thermal degradation and providing outstanding low-temperature pumpability.
Vehicle Background
The 2022 Jeep Grand Cherokee represents a pinnacle of American SUV engineering, continuing a legacy that dates back to the late 1990s. As a mid-size luxury SUV, it sits firmly in a competitive market segment dominated by rivals like the Toyota 4Runner, Ford Explorer, and various European luxury offerings. The Grand Cherokee distinguishes itself by offering a balance of off-road capability, on-road comfort, and a diverse range of powertrains, from efficient four-cylinders to the legendary 5.7L HEMI V8.
Powered by the 5.7L HEMI engine, the 2022 model delivers robust power and a distinctive exhaust note that appeals to driving enthusiasts. This engine is renowned for its smooth power delivery and strong torque, making it well-suited for a wide variety of tasks, from highway cruising to towing trailers and carrying heavy loads. The vehicle’s platform, known as the SK platform, provides a rigid body structure that enhances handling dynamics while maintaining a comfortable ride quality for daily driving. Owners often appreciate the Grand Cherokee’s spacious interior, premium materials, and advanced technology features that keep it competitive in the luxury sector.
Despite its reliability reputation, the 5.7L Grand Cherokee faces a few common issues that can be mitigated with high-quality synthetic lubricants. One frequent concern is oil consumption, which can occur in high-mileage engines as seals harden or piston rings wear. Using the AMSOIL 0W-20 100% Synthetic High-Mileage Motor Oil with enhanced sealing additives can help reduce this consumption and extend engine life. Another issue is carbon buildup, particularly in direct injection engines, which can lead to rough idling and loss of power. AMSOIL P.i. Performance Improver is specifically designed to clean these injectors and restore lost horsepower. Additionally, owners may experience shuddering or harsh shifts in the automatic transmission, especially under load. This is often due to the fluid breaking down over time or overheating during towing; switching to a high-performance synthetic transmission fluid like the Signature Series Fuel-Efficient Automatic Transmission Fluid can improve shift quality and protect against wear. Finally, the cooling system can suffer from corrosion or coolant degradation over time, leading to overheating issues. A high-quality antifreeze that protects all metals in the cooling system is essential to prevent these costly failures and ensure the engine runs at optimal temperatures.
