The 2008 Infiniti G35, powered by the VQ35DE 3.5-liter V6, uses SAE 5W-30 synthetic motor oil. The engine holds about 5.4 quarts with a filter, and Infiniti recommends a full-synthetic oil that meets current ILSAC/API specifications. Always verify the exact requirements in your owner's manual for your VIN and driving conditions.
Recommended oil type and viscosity
The following guidelines cover the essential oil type, viscosity, and certification you should look for when purchasing oil for the G35.
- Viscosity: 5W-30 is the standard recommendation for most climates and driving conditions.
- Oil type: Full-synthetic motor oil is preferred; synthetic blends are acceptable if full synthetic is unavailable.
- Certifications: Use oil that meets ILSAC GF-4/GF-5 and API service category SM or newer for best performance.
- Capacity: With filter, the engine oil capacity is about 5.4 quarts (roughly 5.1 liters); plan to add a little extra to reach the full mark after drainage.
In practice, many owners opt for reputable brands such as Mobil 1, Castrol, or Pennzoil in 5W-30 when performing regular oil changes, ensuring compatibility with the engine’s tolerances and temperature ranges.
Maintenance note: oil change intervals and checks
Proper oil management also involves knowing when to change the oil and how to monitor levels between changes.
- Change interval: Typical intervals are around every 5,000 miles (8,000 km) with synthetic oil, though some climates or driving conditions may extend to 7,500 miles (12,000 km) or more. Always follow the owner’s manual and service records.
- Dipstick check: Check oil level when the engine is cold or after it has been at rest for several minutes, ensuring the level sits between the min and max marks.
- Filter replacement: Replace the oil filter with every oil change to maintain filtration efficiency.
- Torque and hardware: Reinstall the drain plug with the specified torque and ensure no leaks after startup.
Adhering to these steps helps maintain engine protection, optimal performance, and fuel efficiency over time.
Summary
The 2008 Infiniti G35 requires SAE 5W-30 synthetic motor oil, with a capacity of roughly 5.4 quarts including the filter. Use oil that meets current ILSAC GF-4/GF-5 and API SM or newer specifications, and prefer full synthetic. Always verify exact requirements in your owner's manual or with a dealer, especially if you observe unusual driving conditions or different market specifications.
