The 2013 Infiniti G37 uses a full-synthetic engine oil with a viscosity of 5W-30 as the standard specification. In very cold climates, 0W-30 is acceptable if it meets Infiniti’s approved specs. The engine capacity is about 5.1 quarts (roughly 4.8 liters) with a new oil filter.
This article explains the exact oil type, the recommended specifications, capacity, and maintenance guidelines to help you keep the 3.7-liter V6 running smoothly.
Recommended oil type and specifications
Choosing the right oil hinges on meeting Infiniti’s viscosity and performance standards while ensuring ease of cold-start lubrication and long-term engine protection.
Viscosity options and climate considerations
Standard practice for the 2013 G37 is full-synthetic 5W-30. In very cold weather, 0W-30 is sometimes permitted if it meets the same API/ILSAC specifications; always verify against your owner’s manual or a dealer. Avoid conventional oil or lower-grade blends that don’t meet the required spec.
- Viscosity: 5W-30 is the primary recommendation; 0W-30 may be used in extremely cold climates if approved by Infiniti.
- Specifications: API SN (or newer) and ILSAC GF-5 (or newer). ACEA ratings are not required, but compatible oils that meet these specs are acceptable.
- Oil type: Full synthetic recommended for optimal protection and performance; avoid conventional oil for this engine.
Using the correct synthetic oil helps protect the VQ37VHR engine under normal and spirited driving, reduces wear, and supports fuel economy. Always consult the owner’s manual for the most current specification and any manufacturer updates.
Capacity and change intervals
Knowing the correct oil capacity and maintenance interval ensures you add the right amount and service the engine on schedule.
- Oil capacity: Approximately 5.1 quarts (about 4.8 liters) with a new filter.
- Change interval: With full synthetic oil, a typical interval is around 5,000–7,500 miles (8,000–12,000 km) under normal driving; shorter intervals (3,000–5,000 miles or 5,000–8,000 km) are advised for severe conditions or if the vehicle’s oil-life monitor indicates so.
- Monitoring: If your G37 is equipped with an oil-life monitor, follow its guidance in addition to the general schedule.
Adhering to the correct capacity and interval helps maintain oil pressure, engine cleanliness, and overall reliability. When in doubt, rely on the owner’s manual or a qualified Infiniti technician for region-specific recommendations.
Practical tips and common questions
To translate specs into everyday care, keep these points in mind: if you drive aggressively, tow, or operate in extreme heat or stop-and-go traffic, favor the shorter end of the interval and more frequent oil checks. Use a reputable synthetic brand and a compatible filter. Always confirm the exact spec with your vehicle’s documentation, as occasional service bulletins can update recommendations.
Summary
The 2013 Infiniti G37 takes a full-synthetic 5W-30 engine oil as standard, with 0W-30 acceptable in very cold climates if approved, meeting API SN and ILSAC GF-5 specifications. The engine holds about 5.1 quarts (roughly 4.8 liters) of oil with a filter, and oil changes are typically recommended every 5,000–7,500 miles under normal conditions (shorter intervals for severe driving or based on the oil-life monitor). Follow the owner’s manual for the most accurate guidance and keep up with regular maintenance to preserve engine performance.
