Understanding the specific fluid capacities and types is crucial for a proper maintenance routine. The 2016 Infiniti QX70 engine requires 5.2 quarts of 5W-30 motor oil when changing the filter, with a drain plug torque specification of 25 ft/lbs. When performing a complete transmission service, the automatic transmission fluid (ATF) for the 7-speed RE7R01A gearbox requires approximately 9.7 quarts for a total fill. The cooling system holds 10 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. For the differentials, the front unit requires 1.4 pints of 80W-90 AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube, while the rear differential requires either 3 pints of 75W-90 or 80W-90 depending on whether the vehicle is equipped with a towing package. The transfer case, if equipped, holds 2.1 pints. Properly filling these capacities ensures that all critical components are adequately lubricated for safe operation.
AMSOIL synthetic lubricants blow the doors off the highest industry standards. Whether it’s extreme temperatures, long commutes, towing, hauling, or simply extending the time between oil changes, our motor oils will keep your 2016 Infiniti QX70 protected. The AMSOIL Signature Series 5W-30 100% Synthetic Motor Oil is particularly noted for its ability to withstand the stress of the 3.7L V6 engine, reducing horsepower loss and wear by up to 75% compared to conventional oils. The AMSOIL Extended-Life options provide a robust alternative for drivers who prefer slightly shorter intervals while still enjoying synthetic benefits. For vehicles that have accumulated over 75,000 miles, the AMSOIL 5W-30 100% Synthetic High-Mileage Motor Oil is an excellent choice, featuring boosted detergents and dispersants to clean out accumulated deposits and reduce sludge formation by 67%.
The transmission system in the Infiniti QX70 operates under significant stress, particularly in stop-and-go traffic or when towing. The AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is engineered to remain fluid in sub-zero temperatures while providing reserve protection during heavy use. It withstands elevated temperatures and challenging terrain, making it ideal for drivers who push their vehicle. For those seeking a more cost-effective solution that still delivers premium performance, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid offers comparable protection against wear and sludge, promoting smooth, shudder-free shifts.
Maintenance of the drivetrain components is equally vital. The front differential benefits from the AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube, which contains friction modifiers for limited-slip applications and controls thermal runaway. The rear differential, particularly in models with a towing package, requires a high-performance synthetic AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube. This fluid helps reduce operating temperatures and extends the life of seals and equipment. The 75W-110 viscosity option is also available for drivers operating in extreme temperatures or under severe load conditions. Using a Long Life 75W-90 AMSOIL SEVERE GEAR® 75W-110 100% Synthetic Gear Lube is another viable option for those seeking maximum service life.
AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid and AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid are often overlooked but are critical for safety and vehicle control. The DOT 3 and DOT 4 100% Synthetic Brake Fluid ensures excellent responsiveness and stability, even under the intense heat generated during repeated braking. The synthetic power steering fluid reduces friction, helps seals remain soft to prevent leaks, and resists heat for a long fluid life. Together, these fluids ensure that the vehicle’s handling and stopping capabilities remain sharp throughout the vehicle’s life.
