The 2006 Infiniti M35 requires 5W-30 synthetic oil, with an oil capacity of about 5.5 quarts including the filter. Use an oil that meets Infiniti/Nissan specifications and ILSAC/API standards, and verify the exact requirements in your owner’s manual.
The M35’s 3.5-liter VQ35DE engine needs a high-quality, properly viscous oil for reliable performance and protection. In most climates, 5W-30 is recommended, with full synthetic preferred. Always confirm the precise specification with the manual or a certified Infiniti technician before purchasing oil.
Oil specifications and options
Viscosity matters for temperature ranges
For most driving conditions, a 5W-30 viscosity provides good cold-start protection and stable high-temperature performance. Oils labeled for passenger cars that meet API SL/SM or higher and ILSAC GF-4 or GF-5 are typically suitable for the M35’s engine and service requirements.
- 5W-30 synthetic oil (full synthetic preferred) that meets API SL/SM or higher and ILSAC GF-4 or GF-5, compatible with Infiniti/Nissan service requirements.
- 5W-30 synthetic-blend oil as an acceptable alternative if full synthetic is unavailable, provided it also meets API/ILSAC standards.
When selecting oil, choose a reputable brand that clearly states API and ILSAC certifications, and ensure the oil meets Infiniti/Nissan service specifications. Tank capacity includes the filter change, with an approximate total of 5.5 quarts. Always verify the level after refilling with the dipstick and adjust as needed.
Capacity and maintenance notes
The engine holds about 5.5 quarts of oil with a new filter. After a change, run the engine briefly, check for leaks, and recheck the oil level on the dipstick once the oil has settled. Oil-change intervals vary by driving conditions and oil type, but typical guidance is roughly every 5,000–7,500 miles for conventional oil and up to 7,500–10,000 miles for synthetic oil, with adjustments based on the owner’s manual and vehicle usage.
Summary
For a 2006 Infiniti M35, the standard recommendation is 5W-30 synthetic oil, about 5.5 quarts with a new filter. Use oils that meet API/ILSAC specifications and Infiniti/Nissan service requirements, and follow the maintenance intervals outlined in your owner’s manual. If you’re unsure, consult an Infiniti technician or your dealership to confirm the exact specification for your vehicle.
