In most cases, a 2019 Infiniti uses full synthetic motor oil. The exact viscosity depends on the model and engine, with 0W-20 being the most common specification in the U.S. but some engines requiring 0W-30 or 5W-30 in certain climates or markets. Always verify with your owner's manual or dealer.
Oil types by engine family
The following outlines typical oil recommendations by engine family to help you narrow down the right grade. Use this as a guide, then confirm on the label or in the manual.
- 2.0L turbocharged engines (including Q50 2.0t and QX50 with VC-Turbo): Typically full synthetic oil, commonly around 0W-20 or 0W-30 depending on region and climate.
- 3.0L twin-turbo V6 (Q50/Q60 3.0t): Typically full synthetic, often 0W-30; check your owner's manual for the exact grade.
- 3.5L V6 (QX60): Generally full synthetic oil; many markets specify 0W-20.
- 5.6L V8 (QX80): Usually full synthetic oil with a slightly heavier grade such as 5W-30.
Note: The exact grade is model-year-specific and engine-specific. The oil cap and the owner's manual will state the required viscosity and specification (for example, "SAE 0W-20" or "SAE 0W-30"). If you can't access the manual, contact a Infiniti dealer or service center for the precise specification for your VIN.
How to ensure you’re using the correct oil
To verify the right oil, follow these steps:
- Check the owner's manual or the maintenance section for the exact grade and API/ILSAC specifications.
- Inspect the under-hood oil cap, which often shows the required viscosity (for example, "0W-20").
- Look at the vehicle’s information label in the engine compartment for the recommended oil type and capacity.
- If in doubt, contact an Infiniti dealer with your VIN to confirm the correct oil grade.
Keeping track of the recommended oil is important for engine longevity and fuel efficiency. Always use a high-quality full synthetic motor oil that meets the OEM specification.
Summary
Bottom line: For most 2019 Infiniti models, you’ll be using full synthetic oil, with 0W-20 being a common standard and 0W-30 or 5W-30 used in some engines or climates. Always verify the exact grade for your specific model and engine in the owner’s manual or at Infiniti.
