Transmission and Differential Fluids
Transmission fluid plays a vital role in the smooth operation of the 2012 Infiniti M37, which utilizes a 7-speed automatic transmission (RE7R01A) and rear-wheel-drive differentials. The total fill capacity for the automatic transmission is 9.7 quarts. AMSOIL offers both Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid and OE formulations that withstand the rigors of heavy towing, elevated temperatures, and challenging terrain while remaining fluid in sub-zero conditions.
For the automatic transmission, drivers can select AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid to maximize performance and durability. Alternatively, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid provides reliable protection against wear and sludge while ensuring smooth, shudder-free shifts. The AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid and AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid are also versatile options that guard against leaks and promote long-term transmission health.
The rear differential requires a specific type of synthetic AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube. The rear capacity is 3 pints, and the application calls for a GL-5 rated fluid suitable for all temperatures up to 75W-90. AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube is the recommended choice, offering advanced protection against wear, controlling thermal runaway, and reducing operating temperatures. For front differentials requiring 1.4 pints, AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube provides excellent protection and includes friction modifiers for limited-slip applications. Those looking for extreme durability may consider AMSOIL SEVERE GEAR® 75W-110 100% Synthetic Gear Lube or the specialized AMSOIL 75W-90 Long Life 100% Synthetic Gear Lube for extended service life.
Cooling System and Fluids
Maintaining the correct cooling system chemistry is essential to prevent overheating and corrosion in the VQ37VHR engine. The 2012 Infiniti M37 requires a total fill of 8.9 quarts of antifreeze. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an ethylene glycol 50/50 pre-mix formulation that exceeds OEM requirements and protects all cooling system metals, gaskets, and hoses for up to 150,000 miles or 5 years.
For those who prefer a concentrated solution, AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers exceptional protection and a 100% non-toxic, phosphate-free, nitrite-free, and borate-free formula. This concentrated AMSOIL Passenger Car & Light Truck Antifreeze & Coolant must be mixed with distilled water and can provide up to 150,000 miles of protection in passenger cars.
Brake and Power Steering Systems
AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is crucial for the safety and responsiveness of the M37. The system requires a DOT 3 hydraulic brake fluid. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent ABS and traction-control responsiveness with a stable viscosity over a wide temperature range.
AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid recommendations indicate a need for a Dexron-VI type ATF or a dedicated synthetic fluid. AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid is ideal, as it helps seals remain soft to prevent leaks, resists heat for long fluid life, and ensures quiet operation with strong anti-wear protection.
Maintenance Accessories and Additives
Beyond essential fluids, several additives and accessories can enhance vehicle performance and maintenance routines. For fuel system maintenance, AMSOIL P.i.® Performance Improver Gasoline Additive can restore up to 14% horsepower and clean GDI fuel injectors to 100% flow rate. AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor provides additional lubrication to the fuel system and upper cylinders.
For seasonal storage, AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, while AMSOIL Engine Fogging Oil protects internal engine components from rust during inactivity. Cleaning and care products like AMSOIL Power Foam® Carburetor and Induction-System Cleaner maximize horsepower by removing deposits, and AMSOIL Brake and Parts Cleaner ensures brake components are free of grease and oil before reassembly.
About the Vehicle
The 2012 Infiniti M37 is a flagship luxury sedan that showcases Nissan’s engineering prowess under its premium Infiniti brand. Built on the unique D platform shared with the Infiniti Q70, the M37 is renowned for its distinctive design language and dynamic driving character. At the heart of this vehicle lies the naturally aspirated 3.7-liter VQ37VHR V6 engine, a direct evolution of the legendary VQ35 that was celebrated for its high-revving capability, smooth power delivery, and exceptional refinement.
This engine produces substantial horsepower, placing the M37 firmly in the performance sedan category alongside rivals from Germany. It offers a driving experience that balances the comfort expected of a luxury cruiser with the agile handling and responsive acceleration found in sports cars. The M37 typically features a sophisticated rear-wheel-drive layout, often paired with a 7-speed automatic transmission (RE7R01A) that contributes to its smooth and rapid acceleration. The vehicle’s interior is generally praised for its high-quality materials, ergonomic layout, and advanced technology features for its time, such as the Infiniti In-Service Navigation system and advanced safety suites.
Owners of the M37 often appreciate its versatility; it serves effectively as a daily commuter, a long-distance highway cruiser, and a spirited weekend driver. The V6 engine is known for its reliability and durability, but it does require precise maintenance to sustain its performance over time. Regular fluid changes using high-quality synthetic lubricants are key to preserving the engine’s smoothness and the transmission’s precise shifting characteristics. With a well-maintained powertrain and proper cooling system care, the 2012 Infiniti M37 remains a compelling choice for enthusiasts who value a blend of performance, comfort, and Japanese engineering quality.
