Oil Maintenance and Service Tips
Regular oil changes are critical for engine longevity and performance in the Infiniti QX50. Check engine oil levels every 1,000 miles using the dipstick when the engine is cold and on level ground. Full synthetic oil provides superior protection against thermal breakdown and maintains viscosity across temperature extremes.
Oil filter replacement should occur with every oil change to ensure proper filtration of contaminants. Install a new drain plug washer each time to prevent leaks, and torque the drain plug to 22-29 lb-ft specifications. Always verify the correct oil viscosity for your model year, as 2014-2017 models require 5W-30 while 2019-2025 models need 0W-20.
For severe driving conditions, including frequent short trips, stop-and-go traffic, extreme temperatures, or towing, reduce the oil change interval to every 5,000 miles. Monitor the vehicle’s maintenance reminder system, which tracks oil life based on driving conditions and alerts when service is needed.
Normal vs Severe Driving Conditions
| Driving Condition | Oil Change Interval |
|---|---|
| Normal Driving | 7,500-10,000 miles or 12 months |
| Severe Driving (City Traffic, Extreme Weather) | 5,000 miles or 6 months |
| Frequent Short Trips (Under 5 Miles) | 5,000 miles or 6 months |
| Heavy Towing or Hauling | 5,000 miles or 6 months |
FAQs

The Infiniti QX50 requires full synthetic oil. Models from 2014-2017 use SAE 5W-30 synthetic oil, while 2019-2025 models require SAE 0W-20 synthetic oil. Using the manufacturer-specified viscosity ensures optimal engine protection and performance.
How much oil does an Infiniti QX50 take?
The oil capacity varies by model year. Second-generation QX50 models (2019-2025) with the 2.0L turbo engine require 5.0 quarts with filter. First-generation models (2014-2017) with the 3.7L V6 engine need 5.1 quarts with filter.
What is the recommended oil type for an Infiniti QX50?
Full synthetic oil is required for all Infiniti QX50 models. Synthetic oil provides superior protection against wear, better performance in extreme temperatures, and longer service intervals compared to conventional oil. Always use oil meeting API SP certification standards.
What is the oil change interval for an Infiniti QX50?
The standard oil change interval is every 7,500 to 10,000 miles or 12 months, whichever comes first. For severe driving conditions including city traffic, extreme temperatures, or frequent short trips, change oil every 5,000 miles. Follow the vehicle’s maintenance reminder system for optimal timing.
Can I use 5W-30 oil in a 2019 or newer Infiniti QX50?
No, 2019-2025 Infiniti QX50 models require SAE 0W-20 synthetic oil specifically. Using incorrect viscosity can affect engine performance and may void warranty coverage. The 2.0L Variable Compression Turbo engine is engineered for 0W-20 oil.
What is the oil drain plug torque specification?
The oil drain plug should be torqued to 22-29 lb-ft (30-39 N·m). Always install a new drain plug washer when changing oil to prevent leaks. Using a torque wrench ensures proper tightness without stripping threads or damaging the oil pan.
Conclusion
The Infiniti QX50 requires specific oil specifications based on model year and engine type. First-generation models (2014-2017) with the 3.7L V6 need 5.1 quarts of 5W-30 synthetic oil, while second-generation models (2019-2025) with the 2.0L turbo require 5.0 quarts of 0W-20 synthetic oil.
Using manufacturer-approved full synthetic oil and maintaining proper service intervals ensures engine longevity and optimal performance. Replace the oil filter with every oil change and torque the drain plug to specification. Following these recommendations protects your investment and maintains the advanced engineering of the QX50’s engine technology.
