In brief, the Infiniti G37 typically uses synthetic motor oil, with 5W-30 full synthetic being the standard grade for most climates and driving conditions.
The G37, produced from 2009 to 2013 in the United States, runs the 3.7-liter VQ37VHR engine. Using the right oil is essential for lubrication, performance, and longevity. Oil specifications can vary by model year and region, so always consult the owner's manual or a certified Infiniti technician for your exact specs. This article summarizes the current guidance for most G37s and emphasizes the standard practice across model years.
Recommended oil and viscosity
Below are the general guidelines for oil type and viscosity that apply to most Infiniti G37 models. The standard recommended grade is 5W-30 full synthetic, with alternatives noted for specific conditions.
- 5W-30 full synthetic oil (standard recommendation for most climates and driving styles).
- 0W-30 full synthetic oil (alternative for extremely cold climates; verify suitability for your year/model).
- Oil should meet API SN or newer and ILSAC GF-5 compliance.
- Choose a reputable brand and ensure the oil is labeled for gasoline engines.
Bottom line: for typical driving in temperate regions, 5W-30 full synthetic is the safest default. Always confirm the exact viscosity guidance in your manual and heed any regional service advisories or updates from Infiniti.
Oil capacity and change interval
The VQ37VHR engine in the G37 holds roughly 5.5 quarts of oil when including a new filter. Start with about 5.5 quarts and then check the dipstick after the engine has warmed up to ensure you reach the full mark.
As for maintenance timing, Infiniti generally recommends changing synthetic oil every 5,000–7,500 miles under normal driving conditions. If you frequently drive under severe conditions—short trips, heavy traffic, or extreme temperatures—consider shortening the interval to around 3,750–5,000 miles. Always refer to your owner's manual for the exact interval for your specific year and region.
Practical maintenance tips
- Use a high-quality synthetic oil that meets API SN or newer and ILSAC GF-5.
- Replace the oil filter with every oil change.
- After warming up the engine, check the oil level with the dipstick to ensure proper level.
- Keep service records and use OEM- or equivalent-quality filters and oils.
Summary
In summary, the Infiniti G37 generally takes 5W-30 synthetic motor oil (full synthetic is preferred) with an oil capacity of roughly 5.5 quarts including the filter. Use oil that meets API SN or newer and ILSAC GF-5, and adjust viscosity if you operate in unusually cold climates only after consulting your manual. Follow the recommended change interval of about 5,000–7,500 miles under normal conditions, or shorten it for severe driving scenarios. Always verify model-year specifics and regional guidance with the owner's manual or a certified Infiniti technician.
