Engine Oil and Filter Specifications
For the 2007 Infiniti M35 equipped with the 3.5L VQ35DE engine, the recommended oil grade is 5W-30. This viscosity rating ensures the engine receives proper lubrication across all temperatures, protecting vital components from wear during cold starts and under heavy loads at high speeds. The engine oil capacity is 5.0 quarts when the filter is changed, with a torque specification of 22-29 ft/lbs for the oil drain plug.
Selecting the right filter is just as critical as the oil itself. The AMSOIL Oil Filter (EA15K12-EA) is engineered to work seamlessly with synthetic oils, allowing lower restriction to keep parts lubricated while capturing small, wear-causing contaminants. If you prefer the WIX brand, the 51358 filter offers premium media that outperforms standard OEM filters, providing a reliable alternative for maintaining engine cleanliness.
Transmission and Differential Protection
The 2007 Infiniti M35 utilizes the RE5R05A automatic transmission, which requires specific fluid to ensure smooth shifting and longevity. For this vehicle, the total fill capacity is 10.9 quarts. Maintaining the transmission fluid is vital for preventing wear, sludge buildup, and temperature-related failures, especially under severe driving conditions like towing or stop-and-go traffic.
AMSOIL Signature Series Fuel-Efficient Automatic Transmission Fluid offers outstanding protection against the rigors of heavy towing and elevated temperatures. It remains fluid in sub-zero temperatures and provides reserve protection during abuse. Alternatively, the AMSOIL OE Fuel-Efficient Automatic Transmission Fluid provides a robust solution that protects against wear and promotes smooth, shudder-free shifts while resisting harmful sludge.
Regarding the transfer case and differentials, specific gear lubes are required to handle the heavy loads and stress inherent in the drivetrain. The front differential requires 1.4 pints of GL-5 80W-90 gear lube, while the rear differential requires 3 pints of GL-5 90 weight lube. For the transfer case, the capacity is 2.7 pints. AMSOIL SEVERE GEAR 80W-90 100% Synthetic Gear Lube is highly recommended for these applications, as it controls thermal runaway, reduces operating temperatures, and contains friction modifiers for limited-slip differentials.
Cooling and Brake Systems
Proper AMSOIL Passenger Car & Light Truck Antifreeze & Coolant selection is essential for protecting the cooling system metals, gaskets, and hoses from corrosion and erosion. The 2007 Infiniti M35 holds 9.4 quarts of antifreeze. This coolant features a unique poly-organic acid (OAT) formulation that exceeds original equipment manufacturer requirements and protects for up to 150,000 miles or five years. For those needing a concentrated solution that requires mixing with distilled water, AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers extended protection for heavy-duty use.
For the braking system, AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is the recommended choice. This fluid provides excellent responsiveness for ABS and traction-control systems, maintaining a stable viscosity over a wide temperature range to ensure consistent braking performance. Additionally, the hydraulic system can benefit from AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid, which reduces friction, helps seals remain soft to prevent leaks, and offers strong anti-wear protection for quiet operation.
Additional Maintenance and Storage
Beyond the standard fluids, maintaining the fuel system and preparing the vehicle for seasonal storage can significantly impact performance. AMSOIL P.i. Performance Improver Gasoline Additive is an effective solution that restores up to 14% horsepower and cleans GDI fuel injectors to 100% flow rate after just one tank of fuel. This additive also helps reduce the need for higher-octane fuel and controls pre-ignition knock.
If the vehicle is to be stored for an extended period, using AMSOIL Gasoline Stabilizer helps keep the fuel fresh for up to 12 months, preventing varnish and gum buildup. For engine protection during storage, AMSOIL Engine Fogging Oil is a highly effective rust preventive designed to protect internal components from corrosion. Furthermore, a WIX Cabin Air Filter (24479) is available to ensure clean air intake, offering improvements over standard OEM filters for better cabin air quality.
Vehicle Background
The 2007 Infiniti M35 represents a significant milestone in the brand’s history as a luxury performance sedan. Built on the Nissan FD platform, this vehicle shares its mechanical underpinnings with the Nissan Skyline GT-R in terms of the legendary VQ engine family, though it is tuned for refined daily driving rather than track aggression. The M35 is powered by the VQ35DE, a naturally aspirated 3.5-liter V6 engine that produces a smooth and linear power delivery, characteristic of Nissan’s engineering philosophy during this era. This engine is renowned for its balance of power and reliability, making the M35 a compelling choice for drivers who prioritize a high-quality driving experience without the need for turbocharging.
As a member of the Infiniti M-Class, the 2007 model offers a driving character that blends sporty handling with comfortable ride quality. It was positioned in the market to compete with other luxury sedans, offering a blend of sophistication and performance that appealed to enthusiasts and business professionals alike. The vehicle’s design emphasizes aerodynamic efficiency and a sporty stance, contributing to its reputation as a driver-focused sedan. Owners often appreciate the VQ35DE’s responsiveness and the transmission’s ability to adapt to various driving styles.
However, like any vehicle approaching significant age, the M35 can benefit from proactive maintenance to address common wear points. One common issue with the VQ35DE engine is oil consumption, particularly in higher-mileage examples. Using a high-quality synthetic motor oil formulated with enhanced anti-wear additives can help mitigate wear on piston rings and valve guides, potentially reducing consumption rates. Another frequent concern involves the engine’s cooling system, where overheating or coolant leaks can occur over time. Switching to a high-performance antifreeze that exceeds OEM specifications can help prevent corrosion and ensure consistent temperature regulation.
The automatic transmission in the M35 is generally reliable, but fluid degradation over many years can lead to shuddering or rough shifting. Regular fluid changes using a high-quality synthetic automatic transmission fluid can restore shift quality and protect internal components from wear. Additionally, the rear differential in some models may experience wear or noise, particularly if the original gear lube has not been changed frequently. Using a premium synthetic gear lube like AMSOIL SEVERE GEAR can provide the necessary protection against wear and help reduce operating temperatures, ensuring smooth power delivery to the rear wheels.
By addressing these common issues with top-tier lubricants and maintenance products, owners can extend the life of their 2007 Infiniti M35 and maintain the premium driving experience that made it a favorite. Whether commuting daily or enjoying a weekend drive, proper fluid care ensures the vehicle remains reliable and performs as intended.
