Infiniti generally recommends using synthetic motor oil for its modern engines, with the exact oil type and viscosity specified in the owner’s manual and maintenance schedule for your model.
What Infiniti recommends
Infiniti’s official guidance emphasizes following the factory specifications for oil grade and viscosity. Most newer engines are designed to run on full synthetic oil or a synthetic blend, and the required viscosity depends on the engine design and operating climate. The specific grade—commonly 0W-20 or 5W-30—varies by model and region, so verifying in the owner’s manual or with a certified Infiniti service center is essential.
Oil types and viscosity
Below are the viscosity ranges you are likely to encounter in Infiniti maintenance information. The exact grade and whether synthetic is required depend on your specific model and operating conditions.
- 0W-20 synthetic: a common specification for many newer Infiniti engines, favored for fuel efficiency and cold-weather performance.
- 5W-30 synthetic: used for certain engines or climates where higher temperature stability and protection are preferred.
In all cases, verify the exact oil specification for your vehicle in the owner’s manual or by contacting a certified Infiniti service advisor.
Why Infiniti recommends synthetic oil
Synthetic oils offer better protection against viscosity breakdown, improved high-temperature stability, and easier cold-start lubrication. They also tend to hold up longer under the stresses of modern engines with turbocharging and direct injection. Infiniti's engineering and maintenance guidance aligns with using a synthetic oil that meets the required specification to protect engine reliability and fuel efficiency. If your vehicle is under warranty or a maintenance plan, using the specified synthetic oil is typically required.
Maintenance intervals and oil change frequency
Oil change intervals vary by model, driving conditions, and the type of oil used. With synthetic oil, Infiniti generally recommends longer intervals under normal driving—often around 7,500 miles (12,000 km) or more—while severe operating conditions (extreme hot/cold climates, heavy towing, frequent short trips) may require more frequent changes. Always follow the schedule printed in your owner’s manual and have oil changes performed by an authorized Infiniti dealer or a qualified technician.
Note: Some Infiniti models with older specifications or certain diesel engines may have different recommendations; always check your specific model's guidance.
Practical considerations for Infiniti owners
To ensure you meet Infiniti's recommendations, consider these steps when choosing oil and scheduling changes.
- Use oil that meets ILSAC GF-5/GF-6 specifications and Infiniti’s own requirements for your model.
- Prefer synthetic or synthetic-blend options as indicated by your model; do not mix with non-synthetic oils unless specified.
- Have oil changes performed at an authorized Infiniti service center or by a technician who follows the Infiniti maintenance guidelines to protect warranty and service history.
Following these steps helps maintain engine reliability and keeps maintenance records aligned with Infiniti's guidelines.
Summary
Infiniti generally recommends synthetic motor oil for its modern engines, with the exact grade and viscosity specified in the owner's manual. The most common viscosities are 0W-20 and 5W-30, depending on the engine and climate. Always follow the factory guidance and use the recommended oil, having changes performed by qualified technicians to ensure warranty coverage and optimal engine protection.
