The 2016 Jeep Grand Cherokee equipped with the 6.4-liter V8 Hemi engine delivers robust performance and towing capability, but it demands high-quality lubricants to maintain that power and longevity. Because this engine requires synthetic oil and operates under significant thermal stress, using the correct fluid specifications is critical for preventing wear and ensuring smooth operation. From the engine and filter to the transmission and differentials, every component relies on proper lubrication to function as designed. Below are the specific AMSOIL recommendations tailored for this vehicle’s 6.4L configuration.
Recommended AMSOIL Products
Selecting the right lubricants for your Grand Cherokee ensures maximum protection against the unique demands of the 6.4L Hemi engine and its associated systems. These products are designed to outperform conventional oils and fluids, offering extended service intervals and superior resistance to heat and wear.

- AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid – Ensures excellent ABS and traction-control responsiveness with a stable viscosity that resists boiling, even under severe braking conditions.
Proper lubrication extends the life of your 2016 Jeep Grand Cherokee by reducing friction and heat buildup across all mechanical systems. The 6.4L Hemi engine is a powerful unit, but it generates significant heat, especially during towing or mountain driving. The recommended motor oils feature advanced additive packages that resist thermal breakdown and oxidation, maintaining their viscosity and protective qualities for longer periods than conventional oils. By using AMSOIL synthetic motor oil, you not only protect against wear but also maintain fuel economy and engine cleanliness, ensuring your vehicle performs as the manufacturer intended for years to come. Remember that the engine requires 7.0 quarts of oil, including the filter, and a torque of 20 ft-lbs should be applied to the drain plug.
The automatic transmission in this model, typically an 8-speed 8HP70, is a sophisticated component that benefits greatly from high-quality synthetic fluid. Standard fluids can break down under heavy loads, leading to shuddering or harsh shifts. AMSOIL’s transmission fluid is engineered to handle these stresses, providing a buffer against wear and helping to keep the transmission cool. Whether you choose the Signature Series for maximum performance or the OE version for reliable value, both formulas offer superior protection against the heat and friction generated by the transmission’s operation. For the 8-speed automatic, the total fill capacity is approximately 8.8 quarts.
Beyond the powertrain, the cooling system and braking system require attention to ensure safety and reliability. The cooling system holds 16.4 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant, or the concentrated Propylene Glycol Antifreeze and Engine Coolant, which ensures that the engine stays within safe temperature ranges. This product is phosphate-, nitrate-, and silicate-free, making it safe for all modern cooling system components. Similarly, the braking system relies on DOT 3 fluid, which can absorb moisture over time and lower its boiling point. AMSOIL’s synthetic brake fluid maintains a high boiling point and stable viscosity, ensuring consistent pedal feel and responsive braking in wet or hot conditions.
The differential and transfer case systems also require specific lubricants to operate smoothly. For the transfer case, which requires fluid meeting Mopar ATF+4 specifications, AMSOIL’s multi-vehicle automatic transmission fluid serves as an excellent synthetic alternative. For the front and rear differentials, which require GL-5 rated gear lube, AMSOIL SEVERE GEAR 75W-85 provides the necessary protection. This synthetic gear lube contains friction modifiers for limited-slip differentials, helps reduce operating temperatures, and protects against rust and corrosion. Using the correct viscosity and capacity for each axle—1.7 pints for the front and varying amounts for the rear depending on the model—is essential for optimal traction and component longevity.
For air filtration, the WIX Air Filter offers premium media that improves upon original equipment manufacturer (OEM)-branded filters to protect the engine from dust and debris.
In conclusion, caring for your 2016 Jeep Grand Cherokee 6.4L involves more than just following a schedule; it involves selecting the best products available. The combination of AMSOIL synthetic motor oils, filters, transmission fluids, and other lubricants provides a comprehensive solution that addresses the specific needs of this powerful vehicle. By adhering to these recommendations, you ensure that every component of your Grand Cherokee operates with maximum efficiency, protection, and longevity. For further assistance, consult the product labels for specific application details and always verify fluid levels before and after service to ensure optimal performance.
